li ion battery pack Manufacturers

Lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate (LiFePO4) as the cathode material and carbon as the cathode material. The rated voltage of the single battery is 3.2V, and the charging cut-off voltage is 3.6V~3.65V.

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.

There are two basic processes of internal short circuit of battery caused by metal foreign matters, as shown in Figure 1. In the first case, large metal particles directly pierce the diaphragm, causing a short circuit between the positive and negative electrodes, which is a physical short circuit.
