“The Nikkei IBM Laptop Battery Automotive Technology” and “Nikkei Electronics” in May 21, 2004 Yokohama Harbor in the future (Minato-Mirai) Pan Pacific Hotel in the automotive technology integrated seminar “Automotive Technology Day 2004″.


In order to Truck6 “capacitors and lithium-ion rechargeable Laptop Battery,” how about the hp battery and others? As the theme group meeting, the six companies on the rechargeable batteries for hybrid delivered a speech. Among them, the Asahi Glass, Nissan Motor and Yuasa (YUASA), Asahi Kasei Electronics introduced the electric double layer capacitors, lithium-ion rechargeable battery, as well as set capacitors and lithium-ion rechargeable batteries in both the characteristics of a new type of battery.

Asahi Glass Research Institute of AUC central component responsible Kezhi Ikeda said: “To charge the battery(f4809a, f4812a, 319411-001, dell presario 2100 battery, dell presario 2500 battery) in the hybrid using electric double layer capacitors, 1 Law (1F) capacity of at least ¥ 1 costs, future costs need to be Act further ¥ 0.5 to 1. ” Specifically, in addition to lower material costs, but also through the use of high-voltage single-cell design to increase the electrostatic capacity. In addition, by improving the battery pack and the module structure to the success of lower production costs, a method to achieve capacity only cost ¥ 0.5.


In fact, the company re-development of electrode and electrolyte, the successful trial of the voltage from +2.7 V to +3.0 V battery unit. In this way, then the original 1450 law, the diameter of 40mm, high 120mm electrostatic capacity of the battery unit to the 2000 Act. In addition, the end of the year in 2005 to IBM ThinkPad T40 Battery develop the same size, the battery unit 2500 Act.


This cell structure can reduce the cost of production is used in the electrodes do not need to lead the cylinder-shaped unit. The company said that this structure not only can reduce costs, but also can reduce the electrode part of the resistance and to increase the size of the battery(pcga-bp2nx, pcga-bp2ny and a1012, m8244 and gk479, fk890) cell use efficiency.

Lithium-ion rechargeable battery output power density higher

The reason why is committed to the development of lithium-ion rechargeable batteries, Nissan explained that: “lithium-ion rechargeable battery is not only the high energy density and power density can also be based on the existing over increased” (Nissan Institute of Materials Research Horie as a researcher, director of the wise).

Lithium-ion rechargeable battery, such as in graphite intercalation compounds of layered structure of lithium-ion storage and release, that is known as “Intercalation (insert)” the phenomenon to storage. Lead-acid batteries and nickel-metal hydride rechargeable batteries, such as the original battery is a IBM ThinkPad T41 Battery chemical reaction occurs through the replacement of the electrode into other compounds, so decided to use a specific storage materials. As for the case of lithium-ion rechargeable battery(346970-001, hstnn-db02, hstnn-ib04, hstnn-ub02, hp pavilion zv6000 battery, hp presario r3000 battery, hp pavilion zv5000 battery), can store and release lithium ion electrode materials and electrode structures are very common, with the future conduct of research and development, performance is expected to further improve.


For lithium-ion batteries, after one point of view: the use of low ionic conductivity of the electrolyte it is difficult to increase power density. In fact, even the low lithium ion conductivity of the electrolyte, if the increased electrode surface area, reducing the electrode gap, but also improve the power density. Lithium-ion battery as a result of the adoption of the “Insert” phenomenon to storage, so the size of the electrode of the battery than the original expansion of the small. Therefore, the electrode surface area is easy to expand, the electrode gap can be reduced even further.


The best case is: Nissan Motor has successfully developed the original output power up to lithium-ion IBM ThinkPad T42 Battery 1.5 times higher than the slim battery unit, and started in the fuel cell vehicle “X-trail FCV” is equipped with.


AQSIQ random sampling shows that the battery is only 78 percent pass rate
Today, the increasingly widespread use of batteries, increasing consumption, in addition to electronic watches, electric toys, remote controls, walkman, radios, tape recorders, electric shavers and other electrical appliances are commonly used, but also emerged, such as remote keyless entry car key , laser wand instructions, computer power and other new types of pen input devices. This morning, AQSIQ announced battery product samples showed that 32 of the 59 kinds of production products, 46 kinds of qualified products sample only 78 percent pass rate.

The size of the discharge capacity of the scale is battery(acer IBM ThinkPad T43 Battery, acer travelmate 4000 battery, acer travelmate 3000 battery) life. Spot checks of the 10 kinds of products in the discharge capacity of the project failed. According to inspection personnel, as required, the battery must be the production date and shelf-life, Chinese Make the site, plus or minus polarity warning descriptions in Chinese; national mercury limit the provisions of the battery cell must have a mercury content on the logo. But the checks found that some of these are not batteries.

This morning, the AQSIQ has also published on the charger to carry out spot checks of product quality results, Beijing, Guangdong, Fujian, Zhejiang, Shandong, five provinces and municipalities, 21 of the 21 kinds of production products, 16 kinds of qualified, product sampling a pass rate of 76.2%.

Spot checks found that a number of product identification marking and the use of non-standard. Wiring, connections and power supply as well as the structure of failure, and some bolt length is too long, too thick and some thin plug, as well as products that plug into the plug from the edge do not meet standards. Found for the problem of spot checks, the AQSIQ said that the production facilities, production equipment, testing equipment and means of production conditions can not businesses, will be ordered to IBM ThinkPad R50 Battery reform, strict review, fail, and will not be to allow production and marketing-pa3356u-1brs, pa3356u-2brs, pa3356u-3brs, toshiba satellite a50 battery, toshiba tecra a3x battery, toshiba tecra a9 battery and other more hot batteries.
