li-polymer battery 4850mah Manufacturers

Against the background of increasingly depleted oil resources and environmental pollution, electric vehicles have entered a period of rapid development. However, due to the high cost, short battery cycle life, short range and other problems of electric vehicles, further large-scale promotion of electric vehicles is also restricted.

The power recovery decision-making consultation salon co sponsored by the Beijing Association for Science and Technology and the Literature and Information Center of the Chinese Academy of Sciences was held in Beijing Green Space Center yesterday. Fei Weiyang, academician of the Chinese Academy of Sciences, pointed out that in recent years, the key technology of pure electric drive has made great progress, and the core technology of electric vehicles represented by lithium ion has made a major breakthrough. However, the massive application of lithium batteries will also lead to the retirement of a large number of lithium batteries. Therefore, it is necessary to strengthen the research and development of advanced technologies for lithium battery recycling to achieve safe and efficient disassembly and overall recovery of valuable metals and prevent secondary pollution.

Is there any special reason for the use of aluminum foil and copper foil for the current collection of positive and negative electrodes? Is there any problem with using it in reverse?

The differences between li polymer prismatic batteries and cylindrical batteries in application fields mainly stem from their structural characteristics and performance characteristics.
