The battery manufacturing process is mainly divided into two technical routes: lamination process and winding process. At present, the main technical direction of Chinese battery enterprises is mainly around winding, but with the progress of lamination technology, a large number of battery enterprises begin to enter the lamination field.

There are no absolutely safe batteries in the world, only risks that are not fully identified and prevented. Make full use of the people-oriented product safety development concept. Although the preventive measures are insufficient, the safety risks can be controlled.

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.
