Scientists develop new types of carbon nanotubes a tenfold increase in battery life
As smart phones in the functional aspects of the advances, battery life, and life has become increasingly unable to meet the needs of users. Smart phone users have complained that the mobile power capacity as a child, like the rapid consumption of candy. Currently, a new rechargeable batteries in portable electronic products manufacturing technology to solve this problem to bring the dawn of the new manufacturing technology created by the battery power to build ten times the current battery.
MIT scientists have discovered large end of the battery electrodes containing carbon nanotubes can be more than the current lithium Xucun power. Scientists in the lab using multi-cathode cell with carbon nanotubes, using lithium battery anode manufacture of titanium oxide. This battery charging efficiency and storage capacity than most high-end lithium batteries better. With carbon nanotubes in order to verify the performance of the battery service life, scientists developed a new battery with carbon nanotubes 1000 charge-discharge experiments. After 1000 the results of charging and discharging, the battery with carbon nanotubes within the material properties change very little battery power did build unabated. This also shows that carbon nanotubes than the lithium batteries have a longer life.
For the use of smart phones and other portable electronic products, users, this is good news. But this battery with carbon nanotubes is still only at the laboratory research and development stage. Constraints of this new popularity is largely due to the battery, the battery is made with carbon nanotubes in the electrode substrate before the batteries need to dissolve in two different soaking liquid, and this process is extremely time consuming. MIT professor of chemical engineering major Paula - Hammond (Paula Hammond) claimed that her research team are currently working to find a solution to this problem. Currently the most viable solution proposed for the substrate with carbon nanotubes by spray to replace the irreplaceable material in the cell lysate in the soaking time-consuming process.
Believe that this battery is made with carbon nanotubes in the near future can be listed, then the use of smart phone users will no longer need enough power for mobile phones and other problems bother.
Three quarters of German solar cells offer the industry's first match that the two sides
Although both sides offer solar cell factory in the third quarter and second quarter remained fairly flat, but by the euro's benefits, the solar market spread, the German first-line solar cell factory has resorted to in the third quarter of the battery price per watt expected to price 1.1 euros, converted into dollars, and the two sides offer very close to the industry, may be 2004 since the rapid growth of the PV industry, first to see "close quote," still waiting for the market shockwaves.
Depreciation of the euro and by July 1, Kusakabe German solar subsidy rates cut not clarified the impact of the German market in addition to the module industry in the third quarter under notice will cut 10% of the price, recently, a line of German solar-cell factory also reposition itself in the third quarter will be lower price strategy.
Solar industry said that although the plant for the front-line solar-cell factory, but usually the price level is not high-priced range, the current price per watt of battery about 1.2 euros, but in the third quarter came to an estimated ~ 1.1 euros offer an average reduction of 8 %.
The German front-line factory price decline is not, but 1 to 1.1 euros converted into U.S. dollars about $ 1.23 - $ 1.35, in fact, offer has been with the first quarter of Taiwan-based industry spot market price $ 1.35 per watt, rather, may be the sun in 2004 Since the rapid growth of the optoelectronics industry, European solar industry representative quoted rare so close to Asian businesses, particularly the two sides is almost equal to the price of solar cell industry.
Solar industry said that the European system operators benefit from the euro because of the impact, so the price is relatively competitive, but rather because of limited cross industry pressure on the euro, the price cuts have not been able to make it past the the most competitive price advantage resulting passivation, no doubt for the two sides still sit on the sidelines shockwaves through the industry.
Germany under the cut subsidies, the supply chain does move outside the seemingly passive price-competitive Asian district? Solar industry that this trend is no doubt, because the German industry is also a way to reduce production capacity in Europe, and actively the production lines to Asia, and a considerable proportion of the industry from mainland China for OEM production, currently appears to be benefiting from exchange rate fluctuations, resorted to low-cost strategy.
European system of solar energy systems plant frankly, as German factory price has always been more than two sides industry is high, orders will flow to Asia, in the third quarter if the German factory price down to and cross industry rather, it will make a lot of European Department of the module and system Factory can not accept, the flow of orders expected in Europe will also have changed.
Department of solar-cell factory in Europe, including Germany Q-Cells, Solarworld, Schottensolar, Schottsolar, etc. In fact, many industry-based layout to vertical integration, while Taiwan-based battery factory, most of the professional factory including Motech, Yu Jing, solar and other new, continental vertical integrated plant, including Suntech, Yingli, Trina Solar, Solarfun, JA and so on.
