Why implement lithium iron phosphate batteries?
Improvements in safety performance
The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat like lithium cobalt oxide or form strong oxidizing substances, so it has good safety. A report pointed out that in the actual operation, a small number of samples were found to be burning in the acupuncture or short-circuit experiments, but no explosion occurred. In the overcharge experiment, a high voltage charging that was many times higher than the self-discharge voltage was used, and it was found that there were still explosion phenomenon. Even so, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries.
