China's new labor-intensive energy companies to re-take the old path of low-price competition

Chinese energy companies to guard against advances of the new development, re-take the "dummies" export old, "laptop battery grab the market, lost the future"
Text / "Outlook" Newsweek reporters Wang Pan and Wu Tao Sun Ga intern

"Export price less than $ 1,100 in electric bicycle, lithium battery imports accounted for $ 1,000 costs." A new person in charge of energy companies face the "Outlook" Newsweek, filled with emotion that the surface appears to be technology dominant new industry, or labor-intensive to go deep down, low-cost competition, "dummies," the old road.

Reporter at the just concluded 108th Canton Fair that, at present China's booming energy industry around the new, electric cars, solar PV, the new exhibition hall full of energy lighting and other products. However, they conceal the appearance of the brilliant deep concerns: many companies lack core technology, not brand awareness and other reasons, product homogeneity serious, canon BP-512 battery and soon sank into a low-level redundant construction and haphazard open play "price war" vicious competition being.

The photovoltaic industry, for example, presented "one high and one low", "ends out" phenomenon. High solar cell production, installed capacity is very low. In the first producer of solar cells in China, installed capacity is less than ten percent of production; the production of solar cells in China are mostly to be exported, while the main raw materials are imported. How to prevent new industry to "grab the market, lost the future", is timely and relevant departments should become a hot issue of regulation. canon BP-511 battery

No "heart" of the high-tech products

This year's trade with electric vehicles, LED, solar photovoltaic panels for the representative of the new energy industry is undoubtedly the most beautiful in the industry. In this regard, the Chinese Chamber of Commerce and Minerals and Chemicals Association of Electrical and responsible person to the "Outlook" Newsweek said, in addition to the newly created small enterprises, a large number of traditional manufacturing industries in transition to new energy, new energy industry in China is caused by "explosive" important reason for growth.

The rapid increase in international market demand, but also to promote the cause of the solar energy industry booming. New Energy Co., Ltd. Zhejiang Juli pay, general manager of domestic sales of light told our reporter in early 2009, Juli Juli Group was formed a new Energy Co., Ltd., mainly engaged in the current solar modules and project export business, the company's goals by 2015 annual sales of more than ten billion yuan. This is good business for two years,
Canon Camcorder battery
the component in short supply, and now sales have reached 20 billion, at the current rate, less than 2015 target to complete more than ten billion.

However, the front line of indications from the market due to low entry barriers, lack of core technology, new energy industry in China has clearly showed low-level redundant construction, rely on open play "price war" to fight the vicious competition in the export situation.

In the Canton Fair, the Jinan Qingqi Motorcycle Co., Ltd. Deputy General Manager Cao Xincheng reporter pointed to the recent launch of several businesses, said electric vehicles, cost less than $ 1,100, of which imports accounted for the cost of lithium batteries $ 1000 or so, "even the bone cracks (water) are drained."

In his view, the main reason for this situation is that most enterprises do not have to master the core technology of lithium batteries, poor product design, panasonic NV-GS10 Battery "rushed into the market many are blind to each other that price, the results also sold 1,200 last year worth of products, earlier this year dropped to 900 dollars, 700 dollars and now someone shouted, planing and other costs to the battery is basically. "

Embarrassing situation of electric vehicles in the new energy industry are also common in other areas. Accept the "Outlook" Newsweek interview, Golden Sun Electronic Technology Co., Ltd. Quanzhou, president of sales and marketing, said the high birthday to photovoltaic panels, for example, the cut-throat competition and rising costs of basic low-end products are now struggling in cost, high end products can only be maintained up to 10% of the profits. Engaged in the manufacture of new energy lamp beads Haiduomingli ten years manager of New Energy Co., Ltd. Wu Huan said that corporate profits are now less than 10%, mainly due to the homogenization of the product competition is too fierce. panasonic VDR-M50 Battery

"More seriously, the low level of competition, imitation and copy, and also allows the industry at a standstill, progress in production design capacity is weak. Many companies before entering the Hangdang transition, also found that the industry did not, as thought, began to consider restructuring do anything else. "Wu Huan of the reporter stressed.

Zhejiang Baolite respondents Sales Manager New Energy Co., Ltd. increased sharply Lim said the new energy industry is a capital and technology have been "double-intensive" industries, a result, many Chinese enterprises only spent a lot of capital to build the production line, but the lack of the ability to master core technologies and panasonic SDR-H20 battery personnel, which led to the development of crisis-ridden industry.

European and American markets "dependency syndrome"

This session of the Canton Fair from indications that China enterprises to actively join the new energy industry, on the one hand the support and guidance of national policy, on the other hand is subject to government subsidies in Europe and America and other developed countries through the effect of the formation of the market. However, the lack of fully developed in the domestic market situation, with Europe and the United States on related industries in China's rapidly growing trade friction measures, how to avoid the market in these countries highly dependent on our business has been hit hard, cause for concern.

High birthday said that at present most of the new energy industry,panasonic CGR-D16S battery export-oriented enterprises. On the one hand, people in developed countries such as Europe and the United awareness of energy conservation and government subsidies, consumers are more willing to buy energy-saving products; the other hand, although the future of the domestic market has great potential, but energy prices to be higher than the average product prices Many consumers tend to choose cheaper and more traditional products, the domestic market development is still some way off.

With electric cars, for example, Cao Xincheng said that the domestic market, the main use of lead-acid batteries of electric cars, pollution, recycling is difficult, and the use of new energy lithium battery more environmentally friendly electric cars though, but the price nearly a thousand dollars easily in the domestic basic there is no market, only exports to the European and American markets, as these markets given the high government subsidies, "Next year the EU to cut subsidies that I heard, that our industry would be a great impact." panasonic CGR-D08 battery

Fu Liang told the reporter, the development of solar PV panels are not very good domestic market, many companies turned to export development, "now 95% of the domestic component factory for export, and foreign markets if the change, the domestic manufacturers to death a large area. "

Such concerns are enterprises may gradually become a reality. Science and Technology Development Co., Ltd. Jiangsu Yadi Qu Tengfei anxiously Area Manager of the correspondents said, "The lack of national standards, domestic enterprises are in accordance with European standards or specifications to imitate huh production in Taiwan by other countries, market discipline is obvious, but also 'abducted' by our own technical standards setting space, the long-term view, the risks are not small. "

Reflect the number of enterprises, since 2009, by the economic downturn and the recovery of domestic employment and other factors, some countries for the protection of the domestic market, has begun to reject China's new energy products. Fu Liang said that at present some countries have begun to solar panels for the Chinese anti-dumping cases. By Lim added, the international financial crisis, European and American demand for new energy sources and policies are changing,panasonic NV-DS30 battery the United States by the end of October for the survey of 301 out of clean energy is an example, "superimposed under a variety of factors, not excluding the United States do not want to China to seize the commanding heights of the consideration of new energy industries. "

Deep low-end value chain

The photovoltaic industry, for example, a business manager for the correspondents on China's new energy industry in an awkward position.

China is developing rapidly, but not in the value chain, the international financial crisis, the potential risks explicit. In recent years, China's PV industry is often subject to the upper reaches of the silicon material, equipment, industrial chain link in the vacant phenomenon. At the same time of rising prices, upstream firms control the power of strong, often making it cost more than 50% of the entire component.

Basic grasp of polysilicon materials manufacturers in the hands of a dozen countries. Since polysilicon supply and demand gap has always existed,panasonic PV-BP17 battery the high-end materials prices remain high, a huge investment, prompting many companies around them into polysilicon production. According to incomplete statistics, as of the end of 2007, China's under construction and preparation of polysilicon production capacity to 116,720 tons, more than 100 billion investment.

According to the current 10 tons of Chinese / MWp calculation, the amount of silicon solar cells corresponding to about the 11GMWp. But China is still in the low-end silicon technology, backward technology, energy consumption ratio was higher than the world advanced level, while there are some pollution, competition, rapid technological development, the domestic PV market is active, these are potential risks.

From 2006 the cost of the international value chain distribution, battery technology, system installation and components package is part of higher added value. However, component packaging technology and equipment is relatively simple, small investment, quick start, low risk, while labor-intensive aspect of the limited profit margin, its future must be compressed space, it is difficult to become a strategic link in the value chain, but it fit China's relatively low labor cost advantage, and therefore attracted a large number of Chinese companies to enter, greatly lowered the profit of China in this aspect. From 2007 the whole industry chain, China's business is focused on the battery / components and silicon ingots / wafers links, panasonic VW-VBD210 battery sales revenue accounted for 90% of the entire PV industry.

Of course, the domestic production of solar cells has made great achievements or ,2006-2007, in succession a total of 10 Chinese PV companies in the overseas market. Technical level and the international equivalent, but still remains in the introduction, digestion and absorption levels, independent research and development capability is weak.

System integration, the domestic market, many manufacturers, is still the forefront of foreign firms, China's technology is not inferior to foreign countries, China's most independent and 100 ~ 150KW PV system and network system controller / inverter is the basic to achieve national self-development and manufacturing.

Thus, at present the majority of our vendors have failed to grasp the value chain, independent innovation capability is weak. This low-end value chain of China's industry position, as the international financial crisis, making the potential risks become a reality. Polysilicon prices due to cycle, there fell, making the stock decline in value of many companies suffered huge losses, and financing difficulties. Meanwhile, the effects of changing cycle most certainly those of non-strategic areas. According to statistics, since the fourth quarter of 2008, panasonic CGA-DU21 battery China already has about 350 components of corporate bankruptcies, now only 50 or so.

Total investment of 5.0 billion high-performance crystalline silicon solar cell project settled in Tianchang

November 12, from east slope of Tianchang Mayor of Yang and the new president of Sun Liangxin Yuji Yang Holdings Co., Ltd. laptop battery signed a total investment of 5.0 billion high-performance crystalline silicon solar cell project hi down Anhui forever. Tianchang municipal people's congresses, governments, CPPCC leadership, municipal departments responsible comrades, the new holding company responsible Yuji Yang attended the signing ceremony. The signing marks the success of the project will be everlasting in the photovoltaic industry toward specialization, clustering, the direction of base leaps and bounds, creating hundreds of billions in everlasting photovoltaic industry base has laid a solid foundation.

Yuji Yang Holdings Co., Ltd. is committed to the new field of new energy research and development of new technologies, the development of solar cell production equipment and production and the production of solar panels has Yancheng in Jiangsu Province and the MSC, canon CV-11 battery Guangxi Xing, Qingdao, Shandong, Fujian Xiapu, Jeju South Korea to invest in photovoltaic and other solar panel production base.

Tianchang municipal government attach great importance to the cooperation of the holding company Ji Yang, project negotiations during the municipal government site visit to discuss the main leaders on many occasions to invite businessmen to day long field trips. Merchants moved in good faith, with good investment environment and preferential policies to attract customers, contributed to the successful introduction of the project, the project contract from the talks to a lot of time just for a month. The construction of production capacity in Anhui Tianchang 1920MW efficient crystalline silicon solar cell production lines total investment of 50 billion yuan, covers an area of about 700 acres, will be built in the everlasting large-scale, low-cost, high efficiency solar panel production base and technology, canon BP-608 battery equipment, photovoltaic research and development center and a college. The project will be a start before the end of December 2010, put into operation by the end of August 2011, the year after production output up to 50 billion. Second, the three projects were in June 2012 and put into operation before the end of October 2013. All three projects will achieve an annual production output value of 200 billion, revenue of about 8 billion, while solar panels on the core products led the simultaneous development of downstream industries, canon ZR-CV battery economic development zone in Tianchang planning, construction area of 3,000 acres or more The solar photovoltaic industry base, to achieve annual output value of hundreds of billions more.Guard against "overdraft" of development

Lack of core technology, the blind rely on the market - for these two drawbacks, a number of business executives interviewed believe that the current situation of China's new energy industry is booming, that the general right of existing support policies, but should be improved, especially in the standard development, industry consolidation and other aspects of the order to strengthen macro control to avoid the energy industries in the new experience "played up early, catch the late set."

First, we should accelerate the improvement of the standards of new energy industry and policy support oriented, making the domestic market and international market effective docking, to avoid being manipulated by others. Caoxin Cheng said, with electric cars, for example, there is no clear national standards, and related cars quite a mixed bag, the relevant departments should be developed as soon as possible based on the experience of Europe and America, the introduction of the standards in line with our actual needs, so that there is a road to follow the development of enterprises . canon NB-2LH battery

Second, by planning to avoid a new round of low-level redundant construction, and guide enterprises to strengthen the existing brand building. Lin Fu Zeng said, the existing situation indicates that China's solar photovoltaic panels and other new energy industry, the phenomenon of widespread excess capacity in the future if another round of project "launched repeated", the consequences will be very serious. Therefore, the state should be in market access, support policies, etc. to raise the threshold, so that technology has the ability, brand companies have joined in order to protect the industry's sustainable development.

Again, improve the industrial chain, strengthen self-discipline. Quteng Fei said that the State shall strengthen the guiding role of industrial associations and chambers of commerce, so that the new energy industry as early as possible from the current vicious "price war" situation,canon NB-2L battery "price war is serious because the homogenization of electric vehicle products. Deal with this situation, the state should Getting businesses to go its own way, have their own design, has its own characteristics. "

Guozhen Peng admitted that, from the perspective of industry chain, the development of an industry, not only by the core components of the production level of restrictions, the various components of the overall finished product is also affected by the upstream material, accessories, and other downstream constraints, the relevant departments should encourage existing businesses extension of up and down the chain to avoid becoming global "factory", re-take the labor-intensive industries of the old road. canon DM-MV30 battery

Optimistic about the prospects for lithium-ion battery plant in China and Australia GALAXY Resources

Emerging lithium manufacturer - based in Perth Australia GALAXY Resources shares up Laptop Battery today, because there are rumors that the company plans to set up factories in China, production is widely used in rechargeable lithium battery.
Lithium batteries are widely used in mobile phones and hybrid vehicles and electric vehicles, etc., there are great prospects for development. Engage in the production of lithium in China can more easily enter dell laptop battery the Chinese market, saved many of middle-mitigation and transportation costs.
GALAXY Resources has been the site of China’s factory in the Jiangsu Yangtze River International Chemical Industrial Park (Yangtze River International Chemical Industrial Park), the Industrial Park, Zhangjiagang only 500 meters distance. GALAXY Resources CEO Iggy Tan said that the lithium ore from Australia can be easily transported to the plant through the Yangtze River. He disclosed that the plant design capacity was 17,000 tons for lithium. As the supporting facilitiesLatitude D620 around the build-up very well with a number of lithium battery-related industries, the lithium can be easily used to make lithium-ion battery.
Iggy Tan said that the factory will be completed and put into production for the Chinese Li-ion battery industry with a great convenience, consumers will be able to buy cheaper to lithium batteries. He said: “Once the large-scale industrialization of production, price of lithium batteries will come down.”
It is, 312-0386 Resources is the first into Yangtze River International Chemical Industrial Park of the Australian company. Yangtze River International Chemical Industrial Park is located in Zhangjiagang Free Trade Zone, the planning area of 43 square kilometers, is a comprehensive large-scale chemical industry, where there are already some Japanese touch, and Dow Chemical, including dozens of the world’s leading chemical companies settled.

According to foreign media reports, IBM PC764 and the Japanese semiconductor processing enterprises of Applied Chemistry, Tokyo (TOK) jointly announced a joint development of highly efficient solar energy technology, clean energy to reduce production costs.
This is the big technology companies to enter the emerging field of photovoltaic solar energy products the latest action, photovoltaic solar energy in sunlight into electricity at the same time, will not release pollutants. IBM will contribute to battery manufacturers in the technology, while TOK will provide their own in the semiconductor and LCD panel technology coating.
The two companies aim to develop thin-film solar modules will enable the doubling of the efficiency of technology. IBM saidTD175R & D departments, they are not in the solar module production business to cooperate, but we hope in the next 2-3 years will be technology licensing to manufacturers. He said that they have in the negotiations photovoltaic manufacturers.
The two companies will cooperate in the development of 15% of sunlight into power a new type of copper indium gallium selenide solar energy (CIGS) cells, CIGS cells can only be translated into the current 6-12% of the light. Is estimated that 90% of Latitude D820 the photovoltaic solar energy devices to the use of silicon into solar energy, this technology is higher than the efficiency of CIGS, the sun more than 20% conversion rate. However, these cells than thin-film photovoltaic cells thick, limiting the scope of application, at the same time in recent years due to the price of silicon up, is also higher than the cost of thin-film photovoltaic cells.

The use of batteries in parallel on the pros and cons

The use of batteries in parallel on the pros and cons
A long period of time, whether it is domestic or foreign, but also whether or Laptop Battery system, communications system, people are accustomed to using two sets of batteries in parallel with a UPS or a supporting the use of communications equipment. Do not know because the force of habit or because of other reasons, the use of this parallel approach has become the designers and users must follow a principle, but I believe that is totally unnecessary, as long as the users in accordance with the sony battery the use of manufacturer maintenance manual for the dell laptop battery, and only a set of batteries will be enough, not only sufficient, but this group the effect of battery life (such as: battery stability, reliability, balance, in particular battery life, etc.) than with the use of two batteries VGP-BPS2A ,PCGA-BP2V in parallel when the situation is much better. Especially for VRLA batteries is particularly so. So, why the author advocates a positive (or even do not) it would not be appropriate to use batteries in parallel, which parallel the advantages and disadvantages of using it?

First of all, let’s look at the characteristicsInspiron 5100 of parallel circuit. In parallel circuit, the voltage equivalent to the total voltage of the shunt. In other words, plus two sets of batteries in parallel in each group on the dell battery charge voltage and charge voltage equal to the total, that is, U total = U1 = U2. According to I = U / R formula, after the calculation should be able to tell, I1 ≠ I2 (because the two sets of battery internal resistance is certainly not the same, that is, 6T473, in the case of U1 = U2 certainly come I1 ≠ I2 of the results). This means that the size of in the same charging voltage, the two sets of parallel use of the battery pack, which each group received is not the same as the charge current, and resistance of its large charge current small, the internal resistance of the charging of small Current large. In this way, the charge current may be caused by a small group of cells that are often less than the state of chargeInspiron 630m, with the passage of time, this group of cells may be due to the long-term loss of power and more to increase the sulfate resistance, the resistance the greater the charge current is more small, as the result of such a vicious circle caused by the battery life for this group significantly reduced. But only a set of batteries with such a situation does not exist. This point, it illustrates the use of single battery pack is far better than the results of parallel use. Therefore, the authors suggest that users can use a Inspiron 500m battery of equipment to meet the needs of the case, absolutely do not use the use of two Inspiron 640m in parallel, otherwise it will shorten the battery life, increased use of cost, will reduce the battery performance, should not waste money and manpower to do such things. If the large power equipment, with two sets of parallel battery power still can not meet the equipment needs, and the use of more than 2 groups, such as the 3 groups, 4 group, or even more groups to use the battery in parallel, it is no more need , two parallel Y9943 use has resulted in many negative, more of the parallel battery use even more complex, more detrimental to the. In this case, we must choose equipment to meet the power needs of large-capacity battery models can be had, if the 12V series of large-capacity battery is not standard, you can choose the battery 2V series, 2V series of batteries, all kinds of large-capacity all of it can be said that how much you need to be able to make much, as far as I know, currently has the largest battery of 2V series can achieve the 6000Ah, our company can provide the largest to 300Ah.

Of course, the designers and users to improve the reliability of standby power supply to consider this point is understandable, for fear the event of AC power failure, the two sets of batteries GD761 ,KD476 , TD347 in a group can not have another power supply when a set of batteries to that, even though dry matter that is also the value of a waste of resources. If it is from this perspective and consider the use of RC107in parallel, and the author in favor of a maximum of only two sets of battery used in parallel, if more than 2 parallel groups is detrimental to the move. If the non-use of 2 batteries in parallel can not be the case, we should also follow the following principles: First, the use of batteries in parallel must be the same manufacturers, and is the same model, with specifications of the battery; Second, the use of parallel the old and the new state of the hp battery must be consistent; The third is the factory of the same batch at the same time; The fourth is to install at the same time.

Thin-film silicon solar cell transportation system DEZn

At present, commercial production of thin-film silicon solar cells are mainly classified into Laptop Battery amorphous silicon (a-Si) thin film and amorphous / microcrystalline silicon (a-Si / μc-Si) thin-film stack. First of all, its production laptop battery process in the manufacture of glass substrates on Transparent Conductive Oxide (TCO), and then through the PE CVD method of deposition of p-, i-type and n-type films, the last to do the back electrode by sputtering. Preparation of the current industrialization TCO sputtering method (Sputter) and chemical vapor deposition (dell laptop battery), were formed on glass substrates in ZnO: Al or ZnO thin film. Chemical Vapor Deposition of raw materials used diethylzinc (DEZn), its reaction with water to generate ZnO and C2H6.
DEZn is a colorless liquid chemicals, the density of 1198kg/m3, with spontaneous combustion, and water reactive, toxic and other special hazards. DEZn spontaneous combustion in the air to generate Z n O powder, C O2 and H2O, easily lead to burns. Violent reaction occurred with water to produce ZnO powder and C2H6 gas. ZnO on which aquatic organisms are highly toxic, the aquatic environment will have a long-term adverse effects. ZnO powder is also easily lead Latitude D610 to transmission equipment and plug the pipeline. DEZn chemical stability is very low, at 70 ℃ or above begins to decompose at 120 ℃ higher than the decomposition products Inspiron E1505 battery , Inspiron E1705 battery , including Zn, C2H6, C2H4 and H2, etc., would lead to overheating of the explosion vessel. Therefore, it is necessary from the engineering design, operation and maintenance and emergency response312-0068 measures taken to prevent the accident.
DEZn transportation system in the design, first of all an analysis of harm should, through the intrinsically safe design, the elimination of potential safety problems. Secondly, the use of hands to prevent the accident monitoring. Finally, the use of mitigation measures to reduce the consequences of the accident. DEZn for the special nature of the security control system design, process control and purity control technology has taken special measures to realize the material within the 6Y270 cylinder DEZn, security for equipment transported to TCO.
Safety control system valve SS316L pipeline materials, XPS M140 battery and pressure testing and helium leak detection to ensure the integrity of the machinery. DEZn cylinder and control panel placed in the explosion-proof ventilation cabinet shell to prevent leakage to the outside environment. High-temperature cabinet set up a shell and flame detector detectors, fire warning issued in a timely1X793 manner, and to cut off the supply of DEZn. Dry powder fire-fighting equipment for a timely counter shell fire fight. The use of automatic valve to ensure that when the fire broke out with factory isolated ventilation system to prevent the spread of fire along the duct.
Process control, through the regulator nitrogen, the cylinder in a smooth delivery DEZn to the use of equipment. Pressure sensors can monitor pressure conveying system. Electronic scale to monitor weight cylinders to ensure a continuous supply of DEZn. Equipment using pneumatic C1295 valves, to achieve fully automatic operation through PLC.
Purity control system S S316L stainless steel material, and polished by electrolysis. Process valves are valve and connected to VCR. Also taken into account to prevent the decomposition of DEZ n particles caused by congestion. Operation of the site should be equipped with suitable personal protective equipment (PPE) and emergency response equipment and escape routes clearly marked. DEZn operation requires the preparation of and strictly follow the Standard Operating Procedure (SOP), has been done to confirm each step.
DEZn water due to severe reactions occurred, as well as Inspiron 1100 spontaneous combustion in the air, to detect and cut off the source of leakage is to prevent the fire to expand the means of the most fundamental. The solution for the fire station is mainly isolated from contact with air DEZn, are commonly used dry powder fire extinguishing agent, vermiculite, Latitude D520 battery , Latitude D600 battery sand, perlite, etc., prohibiting the use of Halon fire extinguishers, water, foam fire extinguishing agent.
