Foldable Battery News

The U.S. Rensselaer Polytechnic Institute researchers have recently developed a new type of collapsible battery, refreshing.

The battery is the same shape as the paper can be bent, cut with scissors or molded into any shape that people in need. To do the battery acid material is a full sheet of paper, paper with embedded carbon nanotubes. Carbon nanotubes to form electrodes, paper and serve as a diaphragm, electrolyte, so the current can flow. Although this battery is only a few centimeters square, but the researchers believe they tend to be used in the electronics industry and other needs of the smaller, lighter power supply areas.

Rensselaer Polytechnic Institute bio-and interdisciplinary research center, Robert Professor Hom Haat said that this unique place where the battery is that it is an integrated device, rather than a combination of several components.

The researchers believe that the future of this battery can be combined with solar cells to generate solar energy to prepare for contingencies electrical stored. You can even put the battery upgrade, made of motor-home form, if necessary, to reserve the necessary driving force and motivation to offer.

Although these foldable battery to people who are looking for a new power source provides a guideline, but some experts pointed out that, since carbon nanotubes are very expensive, new battery market outlook is to be studied.

Silica Crisis

Silica Crisis

China Sunergy into Laptop battery solar cell production capacity litigation crisis can not be honored

Explosion of silicon solar energy industry is expected crisis casio battery.

Robust in much of the domestic solar energy industry, when suddenly heard discordant voices. Recently there have been media reports in May of this year has just been listed on Nasdaq and Power Electric (Nanjing) PV Co., Ltd. (CSUN), its stock price declines, U.S. investors send China Sunergy court.

China Sunergy face litigation in the U.S. behind China’s solar energy industry, the collective madness behind the enormous hidden – in the casio np-100 battery , casio np-20 battery industry revealed that more than half of solar cell production capacity (700 MW) due to shortage of silicon materials can not be honored, of raw materials in various solar energy companies suffered a widespread tight bottleneck.

Silicon material enterprise losses caused by high prices casio np-30 battery.

China Sunergy head of the Ting-show may not think of their own solar halo behind it so quickly cast a shadow. Two months after landing the Nasdaq, the stock losses due to the company announcement issued a slump. In two months, the company has suffered a U.S. investor litigation.

Some media reports with casio np-40 battery , casio np-l7 battery, September 7, an investor will China Sunergy to court on the grounds that China Sunergy in his book, there is the registration fraud and false statements, allegedly for its “measured by production capacity, is a a leading solar cell manufacturers, “was strong growth in sales revenue, and claimed that it had to ensure adequate supply of polysilicon. The report also said that China Sunergy and corporate executives, chairman of Ting-Xiu Jian-Hua Zhao, Qi Shao-feng, ZHANG Feng-ming and other individuals were named as defendants.

Proceedings from China Sunergy in a paper bulletin, China Sunergy August 24 this year, issued a public notice that its second-quarter net profit from last year’s 1.84 million U.S. dollars per share American Depositary Shares (ADS) 9-US points to a net loss of 3.54 million U.S. dollars a share, 14 cents. Shares fell from 16.7 U.S. dollars per share of around 5 U.S. dollars.

The insider to the “China Times” reporter revealed that in China Sunergy CFO Qishao peak after, CEO has also been left by the former vice president of NEC Corporation Allen took over (in Chinese known as Run-Sheng Wang dell inspiron 630m battery , dell inspiron 640m battery).

“’s Loss was largely due to the price of raw material procurement to be a little higher than other companies, while former members of the company is relatively overstaffed.” China Sunergy an anonymous person in charge of the World Solar Energy Conference held recently to accept the “China when the newspaper, “an interview, said:” Because we have no long-term and stable raw material suppliers. ”

As the main raw material for solar cells, polycrystalline silicon and monocrystalline silicon have been in short supply, the global solar energy companies are facing raw material shortage. The person in charge of raw materials in 2001 from 30 U.S. dollars / kg or so, rose to the current 300 U.S. dollars / kg. with dell inspiron 600m battery

, “The company’s cost pressures are significant, not only that, even if the price is so high it is difficult to buy raw materials. Because we are facing this problem.” The person in charge further stated.

700 MW of capacity can not be honored

“2006 China solar energy companies production capacity has reached 1,200 megawatts, but actual production is only 500 megawatts.” According to the disclosure of the above-mentioned person in charge of domestic solar cell production capacity, more than half of the reasons for the supply of silicon material in a shutdown state dell inspiron 500m battery , dell inspiron 510m battery.

Obviously not just China Sunergy encountered a bottleneck, solar companies are more or less the existence of such conditions. Even the first overseas listing of domestic solar PV companies – Suntech, he was unable to avoid.

“Suntech also true that there is problem of the shortage of silicon materials, because our capacity expansion more severe.” Suntech Marketing Director Wu Hongyan accept the “China Times” reporter, said: “But we have with other companies have not, we have a stable supplier dell inspiron 1520 battery. ”

It is understood that by the end of July this year, Suntech with the world’s ten largest suppliers of silicon, the United States New York Stock Exchange Main Board-listed MEMC signed a silicon supply contract. The two sides agreed, MEMC will be in the next 10 years, providing value to Suntech over 5 billion to 60 billion dollars in solar-grade silicon.

“Suntech’s total supply of silicon material, the long-term contracts accounted about 70% of the ratio of 30% of the other.” Wu Hongyan, said last year, Suntech’s output is 320 megawatts, ranked third in the world. Nevertheless, Suntech also failed to go full steam ahead last year, its actual production capacity dell inspiron 1521 battery has reached 480 MW.

By contrast, other companies do not have such good luck. Newspaper reporters in an interview with the World Solar Congress a number of solar companies, solar companies have said the pieces of silicon materials has been a headache.

“Silicon is expected to be around 2010 the problem can be resolved dell inspiron 1721 battery.” China Merchants Securities analyst Wang Sheng told the “China Times” reporter, “the face of huge market demand, many companies are actively to increase production.”

It is understood that this year, China has launched several companies threatened to polysilicon project. Daqo Group, Jiangsu, Sichuan, Tong Wei Group, Shaanxi Nonferrous Metal Group dell inspiron 6400 battery , Jiang Xi Sewei LDK will be launched thousands of tons of the size of polysilicon, particularly among the most eye-catching Jiang Xi Sewei LDK. The company said it will invest 12 billion yuan to develop 15 thousand tons polysilicon project.

“Today’s technology dell inspiron 1720 battery , primarily in the hands of Europe and the United States, China has yet to master the polysilicon production technology.” Wang Sheng said, “Although part of the silicon material to produce a little polysilicon manufacturers, but the amount is very small. They mainly use Russian technology, but the Russian technology and techniques vary widely in Europe and America. ”

“Once the technical success, raw material problems will get through.” China Sunergy person in charge of the case of the above-mentioned prospects of China’s solar energy dell inspiron 6000 battery business development prospects.

Zinc market

Zinc market microstructure and price changes in the relationship between the

(1) inventory and price changes fujitsu fpcbp101 , fujitsu fpcbp102

According to the law of the past, inventory and price changes in a negative correlation. The latest statistics show that, LME zinc stocks of 88,475 tons, stocks are still relatively high in recent months and canceled warrants 4125. Inventory increase is not sustained substantial, but the price collapse of Type drop should be understood as the surplus for 2008 ahead of the market to digest.

(2) positions and price changes fujitsu fpcbp101ap , fujitsu fpcbp102ap

Since mid-October 2007 has been a dramatic drop in zinc 30%, mainly due to the new short approach, a substantial increase in positions 17500 hand (+11.4%). Short position except, of course, the zinc price decline is mainly because the supply of zinc concentrate significant increase in the market to see an empty result.

(3) inventory increase or decrease in the water up with the quote change

Inventory and bids for both the spot in order to reflect the supply fujitsu Esprimo Mobile V5515 Battery and demand indicators, but is usually between the two negative correlation.

Changes in these three areas would be more direct impact on prices in 2008 to determine the trend of zinc prices also will be based on these data, specific judgments, after all, the market is rapidly changing.

4. The state of zinc is not a price adjustment of tariffs, the key to fujitsu Esprimo Mobile V5535 Battery

In the end of 2007, there has been speculation 0 # zinc 5% of the export tax rebate was abolished in 2008, replaced by a 5-10% export duty levied, making Shanghai zinc futures continuous explosion-down in the past, China’s refined zinc exports statistics analysis, we believe that short-term export policy adjustments may put pressure on domestic zinc city fujitsu Esprimo Mobile V5555 Battery, but the long-term zinc price will be supported.

The Gel batteries

Gel batteries are lead-acid Sony np-qm71d batteries in a development category, the easiest way is to add a gelling agent in sulfuric acid to sulfuric acid into a colloidal electro-hydraulic. Electro-hydraulic battery was generally known as colloidal gel batteries.

Broadly speaking, the conventional lead-acid Jvc bn-vm200 batteries gel batteries difference lies not only in gel-like electro-hydraulic changed.

For example, non-condensing water-based gel, from the electrochemical classification structure and properties to see the same gel batteries. Another example is the knot in the grid attached to polymer materials, commonly known as the ceramic grid, can also be regarded as the application of characteristics of gel battery for Samsung sb-l160 . Recent laboratory plates have been added to a targeted formulations coupling agent, greatly increased the utilization of electrode active material’s response, according to non-public information that can be achieved 70wh/kg weight ratio of energy levels, which are at the present stage of industrialization of industrial practice and to be examples of the application of gel Nikon en-el8 batteries.

Gel batteries and the distinction between conventional lead-acid Jvc bn-vf808 batteries, from the original understanding of the electrolyte gel, and further developed to electrolyte-based electrochemical properties of the structure, as well as grid and the active material in the application and popularization. Its most important features are: cost of using a smaller industry, along the existing 150-year-old lead-acid akku industry, ways to create better battery, its discharge curve straight, knee high, in particular the specific energy than the specific power conventional lead-acid batteries at 20% or more life than conventional lead-acid Fujifilm np-120 batteries generally about twice as long, high temperature and low temperature properties are much better.
