Are lithium iron phosphate batteries safe?

Lithium iron phosphate battery is a kind of lithium battery. At present, BYD E6, BAIC EV160, Tengshi and some other electric vehicle processing companies use it as the power source for cars. At present, the thermal stability of lithium iron phosphate batteries is the best among automotive lithium batteries. The safety of lithium iron phosphate batteries is second to none in lithium batteries, and because of this, it has also become one of the most important categories of electric vehicle batteries. When the battery temperature is 500-600°C, the internal chemical composition begins to be analyzed, and the internal chemical composition of the lithium cobalt oxide battery belonging to the same lithium battery is already in an unstable state at 180-250°C. In other words, among lithium batteries, the safety of lithium iron phosphate batteries is second to none. Because of this, it has become one of the most important categories of electric vehicle batteries. The P-O bond in the lithium iron phosphate crystal is stable and difficult to analyze. Even at high temperature or overcharge, it will not collapse and generate heat or form strong oxidizing substances in the same structure as lithium cobalt oxide, so it has good safety. A report pointed out that in the actual operation, a small part of the samples were found to burn, but no explosion occurred. In the overcharge test, a high voltage charge that was several times higher than the self-discharge voltage was used, and it was found that there was still Explosion phenomenon.
