Lithium Battery and Hybrid cars

Lithium Battery and Hybrid cars

The New York Mercantile Exchange, August crude oil futures prices for delivery in July 3 145 U.S. dollars a barrel, the highest recorded. In this week, OPEC weekly average oil prices to new highs. In fact, for some time, high oil prices and the resulting series of political and economic and social issues deeply hurt the car manufacturer. In the United States, the three auto makers have cut production of large pickup trucks, SUV, increase energy-saving small cars or crossovers. However, changing the structure of existing products, while car manufacturers have already "obvious": before you have to master the technology of alternative energy vehicles.

"Battery is the core issue." General Motors R & D lab materials laboratory director Mark? Sheet Mubarak said. Have been successful experiences with a certain market hybrid car, the battery technology in deciding the fate of the car key. It is understood that currently includes the Toyota Prius (configuration parameters Gallery) models, including hybrid vehicles use nickel-metal hydride batteries. And the battery technology itself has limitations. Remove the price factors, on the one hand, the decision by the material limits the size of storage capacity, lack of capacity Ni-MH battery life, on the other hand, it can not be extrapolated charging.

Li-ion battery is a high voltage, charge and discharge, long life, fast charging, self-discharge rate, wide operating temperature range, etc., have become the most cars and parts enterprises and the main direction of choice. Data show that, compared to nickel-metal hydride batteries, hybrid electric vehicles using lithium batteries can make the weight decreased by 40% to 50% and the volume reduced by 20% to 30%, energy efficiency has improved to some extent. Optimistic forecast said that in the near future, the vehicle will decrease the cost of lithium batteries to nickel-metal hydride battery 2 / 3.

Chinese stainless steel market on October 9 Nickel-based product pricing plunge

Chinese stainless steel market on October 9 run remains in the doldrums, the market traded good, pessimistic atmosphere filled the air, nickel stainless steel products fell sharply quotes, 200 series, 400 series also showed downward trend.

London Metal Exchange LME nickel 9 October opened at 13,800 U.S. dollars / ton, closing at 13,200 U.S. dollars / ton, 228 tons less inventory, total inventory is 55,032 tons. Shanghai No. 1 electrolytic nickel market on October 9 prices continue to decline, in the 113,000 to 117,000 yuan / ton, the average price of 115,000 yuan / ton, down 7,750 yuan / ton; 1 reported that 115,000 to 117,000 Jinchuan Nickel yuan / ton, the average price of 116,000 yuan / ton, down 7,750 yuan / ton. October 9 nickel price continued to fall, and the amplitude is relatively large, the spread of market pessimism, the overall trend showed sluggish operation. Futures market and the whole face of the recent financial market prices, the central bank, exchange, etc. have "Sword", or cut, or forced to lighten up, or raising margin and so on, in order to stabilize markets and resolve risks. Can be stabilized to some extent market interest rates, commodity prices have weakened in the short term decline in the likelihood. However, if there is no follow-up to the introduction of the economic rescue plan, I do not rule out possible further decline in commodity markets.

Chinese stainless steel market on October 9 extending over the last few trading days of the downward trend, and the decrease in the expansion. Market pessimism filled the air, although the decline in nickel prices has narrowed the previous session, but the 9th London nickel and both the domestic spot price of nickel fell sharply, the stainless steel market under great pressure, especially nickel stainless steel, the more resources, demand poor circumstances, the offer is substantially reduced, Wuxi, Foshan, 300 series stainless steel offer the market fell sharply, part of the specification much more than the previous trading day decline, 304,309 S, 310S spared, sales of 304 products fell 1,000 to 1,700 yuan / ton. A huge sell-off spot market, traders generally expect to sell low-cost, mitigate the latter may again bring down the economic losses. Wuxi Steel 4 mm 304/NO.1 mainstream market transaction prices in the 21,500 yuan / ton, down 1,000 yuan / ton; Foshan 304/2B TISCO 2 mm market transaction price in the mainstream of 22,900 yuan / ton, down 1,000 yuan / ton. 200 lines, the product pricing in the falling nickel, stainless steel pressure to crack down on market downturn, the traders are not optimistic about the market, Foshan market transaction price of 200, Department of confusion again, some traders offer lower. Department of respect across the board 400 is lowered turnover remains at low, decline more obvious, but the rate of decline is not too much. Wuxi market down 430 base price of cold roll, big offer concentrated in the 11,400 yuan / ton, medium and small household purchase is concentrated in the 11,200 yuan / ton to 11,400 yuan / ton, Foshan market, the overall trend of 400 lines down across the board decline in the basic 100 yuan / ton. 11,200 compared to pre-yuan / ton to 11,600 yuan / ton, taking into account the sharp decline in nickel-based stainless steel, or will make further converting 400 series, 400 series outlook is worrisome.

200 line, the Wuxi market mainstream Lianzhong 201/2B plate bending 1.0 mm quoted 14,100 yuan / ton, down 100 yuan / ton, Wuxi market OurGame 201/NO.1 4 mm offer for mainstream flat-panel 14,200 yuan / ton, down 100 yuan / t; Foshan market Lianzhong 201/2B plate bending 1.0 mm quoted 15,600 yuan / ton, Foshan market Lianzhong 201/NO.1 4 ~ 5 mm coil 1.0 mm quoted at 13,600 yuan / ton, down 200 yuan / ton. 300 line, the Wuxi Zhang Pu production 304/2B plate 2.0 mm reported 21,000 yuan / ton, down 800 yuan / ton, Po new capacity 2.0 mm reported 21,000 yuan / ton, down 800 yuan / ton, TISCO 304/NO.1 Flat 5 mm reported 20,600 yuan / ton, down 700 yuan / ton, Zhang Pu reported 20,500 yuan / ton, down 700 yuan / ton, Foshan 304/2B TISCO coil 2.0 mm reported 22,900 yuan / ton, down 1,000 yuan / ton Zhang Pu reported 23,200 yuan / ton, down 1,000 yuan / ton, Jiuquan 304/NO.1 Coil 4 mm reported 22,500 yuan / ton, down 300 yuan / ton, Bao Steel Coil 4 mm reported 304/NO.1 22,800 yuan / ton, down 300 yuan / ton. 400 line, the Wuxi 430/2B TISCO 2.0 mm coil mainstream quoted 11,400 yuan / ton, Po is the new 2.0 mm major purchase 11,400 yuan / ton, down 100 yuan / ton, 430/No.1 Taiyuan Iron and Steel plate 4 mm Mainstream offer for 10,300 yuan / ton, down 200 yuan / ton; Foshan 430/2B TISCO 2.0 mm coil mainstream offer 11,500 yuan / ton; Foshan 430/2B coil 2.0 mm Zhang Pu mainstream offer 11,600 yuan / ton, down 100 yuan / ton.

USB 3.0 is certainly not a bad technology, only the support and implementation is currently still lacking. Then the next standard will be officially endorsed by any mainboard chipset, the manufacturers have to turn to the finished product special chips, which now make in notebooks USB 3.0 executable.

One of the most distinctive features in the new U series from Asus is the very fact that it relies on USB 3.0, which also had to be resolved through additional chips, as Intel does not support this innately. In addition to the U-series models will also have the N and NX series of USB 3.0 support.

Whether Intel, AMD to make every effort to reduce the power consumption of the hardware platform, and now laptops are unable to obtain all-weather 8-hour battery life, the key crux of the problem lies in lithium battery technology limitations, it is difficult to provide a high enough capacity. Two years ago, fuel cells, once is quite strong, but now attributed to silent, of course, fuel cells can provide longer battery life, but it's inconvenient to use, and the high cost of sales in consumables way, it is difficult to obtain broad market recognition, development of high-capacity lithium battery technology has become the industry consensus.

Stanford University announced today that one of their team in the field of lithium batteries was a revolutionary breakthrough, the research team has successfully developed a silicon nanowire technology, you can increase the capacity of lithium batteries 10 times, if you use this new type of battery , notebook computer battery life performance increase from the current two hours to 20 hours or more! Developers believe that this technology is not similar to the type lithium polymer technology improvements, but rather bring about revolutionary progress!

We know that the capacity of lithium-ion battery(Dell Battery , dell C1295 , dell D5318 ,dell GD761 , dell GK479 , dell KD186 , dell KD476 ) anode from the lithium ion can attach the number of decisions, attached greater the number of lithium-ion battery capacity of the greater! In the charging process, with the positively charged anode of lithium-ion will be absorbed by silicon material, making expansion of silicon material; in the work of discharge, lithium-ion will be released from the silicon to make silicon material shrinkage occurs - this expansion and contraction will lead to repeated silicon to become powder, resulting in diminishing the capacity of the battery. Stanford research results to solve this problem, they used nano-technology is made of silicon nanowires as the anode, and in the absorption of lithium ions can be expanded four times, while in the discharge process would not lead to powdering, or broken, which means not only to ensure that the battery capacity increase 10 times, and can significantly extend battery life.

The research team did not say when it will push the commercialization of this technology, according to Stanford's entrepreneurial culture, the research team can use the research results of the establishment of enterprises, by way of technology licensing operation, if the silicon nanowire lithium batteries can be really involved in commercialization, it will completely solve the shortage of digital devices, battery life, short life problem - then your laptop could easily rely on batteries to work 20 hours or more, so that the battery mode, the hardware performance do not have to drop too low; UMPC, smart phone, etc. handheld devices can also be obtained rapidly.

Rongshida polymer lithium battery

June 27, Guangzhou, sanyo battery there were two mobile phone explosion; Not long ago, close to Hefei, Luan also taken place with the mobile phone explosion – but perhaps shortly after, with the production of polymer lithium batteries in Hefei in the market control of the voice this kind of tragedy will not be repeated.

How to carry cell phones to explode it? Battery expert – Rongshida Li Jianguo, general manager of the new energy company told reporters that the current mobile phone batteries on the market, almost all lithium batteries, can be divided into liquid lithium sanyo db-l20 battery, lithium-polymer two categories, and more than 90% of the battery is liquid lithium, and the use of steel and aluminum shell. This liquid lithium batteries in over-charging, high temperature, collision and other extreme cases, might lead to short-circuit, once the short circuit, battery cell will be inside the organic electrolyte electrolysis and produce gas, and in severe break through the shell, exploded.

It is understood that production of polymer Rongshida is developing lithium batteries, the sanyo db-l40 battery using the flexible packaging, even if the internally generated gas, will only expand, or earlier breakthrough in the shell, avoiding the fierce explosion, thus more secure. “At present, Ministry of Information Industry is developing uniform standards for mobile phone batteries.” Hefei Economic and Trade Commission official said, with the introduction of battery standards, Hefei safety of batteries will produce in the market, “pre-emptive.”

TD mobile phone battery manufacturers is still plagued by problems caused by increasing power consumption application of multi -

In a recent TD-SCDMA Forum, relevant meetings sony battery, TCL Group, Industrial Technology Research Institute, vice president of Wang Kai-Long said the current development of TD terminals have to face many challenges, including TD mobile phone battery is still the key point.

He said, since the majority of 3G phones will be multimedia phone, and TD technology itself has the corresponding requirements for power sony np-bg1 battery, so power-hungry will make TD terminal batteries seem difficult to sustain, the battery power is a major problem.

Previously, TD mobile phone battery has been very concerned about the operators and users of the problem, once there is news that the technical difficulties TD mobile phone batteries have been basically solved.

According to the requirements of the relevant operators acer aspire 3000 battery, TD-SCDMA handsets in 2008 will enable videophone, mobile TV, location services, mobile Internet, 3C interconnection functions.
