The lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate (LiFePO4) as the negative electrode material and carbon as the negative electrode material. During the charging process, part of the lithium ions of the lithium iron phosphate will escape, pass through the electrolyte to the cathode, and intercalate the cathode carbon species.

According to the foreign media The Verge, batteries sometimes explode. Those explosion videos are scary, but scientists and startups have been working hard to build safer batteries. They are improving the battery design and testing new materials, hoping to solve the safety problem once and for all. But every method seems to have a trap, and the most practical solution at present may be the most boring. There are three strategies to improve battery: avoid using flammable liquid as solid battery; Make the battery module fireproof; Modify the existing functional characteristics of the battery slightly. At least as far as batteries are concerned, this change may come

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.

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.

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.
