Rechargeable notebook batteries could explode
With simple maintenance procedures, notebook battery the cost of re-work cost only one-eighth of the purchase of new batteries. Yesterday, the reporter visited the Zhongguancun learned the insider sales. Professionals to remind consumers that this kind of “core exchange” battery There is a certain security risk.
Vote in the country and in the sea of electronic markets, to engage in second-hand notebook business transactions are that they can provide such as “for the core” of maintenance services. IBM600E as an example to the original battery, “for the core” cost about 300-400 yuan, and its process is very simple, just have a basic spot welding equipment and technology can be completed. In the repair site, the repair personnel to break open the original battery, will the old batteries (similar to common rechargeable batteries) out, and then as it will be in accordance with the new batteries will be followed by spot welding to connect the success of the whole when there is no more than 30 minutes. “In fact, most of the laptop dell battery, dell inspiron e1505 battery can not recharge batteries as a result of aging are caused by the battery as long as the control board did not let the bad, the maintenance of nearly 100% success rate.” The businessmen explained that the business also revealed that At present, batteries are in circulation are from the South to buy large quantities. Electronic market in the South, “for the core,” has long been no secret, just before the beginning of this year a large number of emerging electronic markets in Beijing, but also popular. “In the ‘Blue Express’ where to buy a piece of the price of a new battery at least 1,000 yuan more than that many clients are it’s cheaper to come.”
“Blue Express” the technical staff, told reporters that private “for the core,” there is a big security risk, some testing batteries without charge even after the bursting of short-circuit phenomenon, ranging from damage to the host, then re-explosion .
A staff member confirmed that the purchase of new 600E battery takes about 2,400 yuan. The difference between the prices, “Blue Express” the Propaganda Department of the Miss Yu said, IBM has its own pricing strategy worldwide, the company did not modify the permissions, and whether the choice to repair the battery is the client’s freedom.
Ni-MH battery manufacturer to achieve domestic production of key materials
863 plans was included in the first article of our Ni-MH battery plate production line by the end of October in Beijing Airport Development Zone, completed and put into production, thus one of these products accounted for 80 percent of China’s market share.
Ni-MH battery production of materials for nickel and rare earth metal, it features excellent environmental protection and small, and characteristics of high-energy, since the 80’s has been widely used in mobile phones, portable computers, mobile messaging products. Into the 90’s, with the nickel-metal hydride battery production technology, its service life can be further improved, as a vehicle to replace the fuel the engine of choice for electric vehicles, power storage device. Therefore, the nickel-metal hydride batteries and related materials by Ministry of Science and Technology in China during the Ninth Five-Year Plan as a key development project of the top ten.
In order to fully exploit the advantages of our resources to address the effects of Ni-MH battery production of key materials for nickel-plated steel punching in China, and Beijing to jointly develop metallurgical engineering and technology research centers and Shenzhen Guang-Yuan Industrial Co., Ltd. jointly developed a new success with self-knowledge 14-high mill property and ultra-thin strip production line for electroplating, the use of domestic steel production, such as Baoshan Iron and Steel’s raw materials, can be successfully rolled completely comparable to foreign products and nickel-plated steel punch. It is reported that the establishment of two joint co-operation with the Beijing-Canton Airport Metal Materials Co., Ltd. has been far from an annual production capacity of 3,000 tons and 1,000 tons of ultra-thin strip punching capacity of nickel-plated steel to meet domestic demand for 80% of the market.
Ni-MH battery pack and test related materials and technology through the identification of integration
Recently, the China Nonferrous Metals Industry Association of the Beijing Institute of Technology experts, national high-tech new energy storage materials engineering and development centers to complete the “nickel-metal hydride hp batteries, battery packs and related materials and technology integration test” project conducted to identify scientific and technological achievements.
Experts believe that: the preparation of this project in the alloy, electrode surface modification, additives modified, letters straight into the battery, the battery residual capacity of sorting into groups, the design of new catalysts, EV, HEV battery power with the new structural design and preparation, the battery internal pressure and heat control, battery life, rapid assessment, rapid welding rectangular battery for use exclusively with the key technical aspects of closure, have made major innovative technological breakthrough and the first in China to develop a very successful film for automated test line, automatic assembly line for cylindrical battery , computer-controlled battery into detection equipment.
The project R & D batteries, battery testing organizations by the State authority detection, the main performance indicators have reached international advanced level, some of which performance indicators have reached international advanced level. With the hybrid electric vehicle is about the industrialization of the demand for high-power nickel-hydrogen batteries will also be facing a huge new market. This project will upgrade China’s automobile industry and the Ni-MH battery industry play an important role in the take-off.
With “Lightning paste”, the phone will bid farewell to the battery?
Held a few days ago, the fourth “Challenge Cup” Chinese students start their own business plan competition, the 2003 Department of Chemistry, Fudan University, the doctoral students involved in the design of rock-way one-time ultra-thin battery “Lightning paste” project won a gold medal. Experts believe that this project is expected to solve the problem of mobile phone users — the biggest problem with the battery performance issues.
“Lightning paste” is a one-time nano-high-energy ultra-thin cell phone battery is a thin sticky trap shape, When will it be affixed to the back of the battery plates, it immediately calls. This ultra-thin printed battery contains energy, and continued for 34-38 hours of standby time, not only to meet temporary emergency, but also as a mobile back-up battery. Experts believe that, with the “Lightning paste” technology, it is possible to replace bulky complete mobile phone 367759-001 battery, hp hstnn-ib09 battery.
“Lightning paste” scientific and technological innovation in the Fudan University, funded by special funds to complete the technology development, and technical patents, and its market prospect has aroused the concern of experts and investors.
