Advantages of lithium iron phosphate battery 1. Improvement of 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 of acupuncture or short circuit experiments, a small part of the samples were found to burn, but no explosion occurred. In the overcharge experiment, high voltage charging that was several times higher than the self-discharge voltage was used, and it was found that there were still Explosion phenomenon. Nevertheless, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries. 2. Improved lifespan The cycle life of a long-life lead-acid battery is about 300 times, and the highest is 500 times, while the cycle life of a lithium iron phosphate…
