Improvement of safety performance of 10kwh LiFePO4 battery china
The P-O bond in lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat or form strong oxidizing substances like lithium cobalt oxide, so it has good safety. Some reports pointed out that in the actual operation, a small part of the samples were found to burn in acupuncture or short-circuit experiments, but no explosion occurred. In the overcharge experiment, a high voltage charge that was several times higher than the self-discharge voltage was used, and it was found that there were still some samples. explosion phenomenon. Even so, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries.

Improvement of lifespan
Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as the positive electrode material.
The cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the cycle life of lithium iron phosphate power batteries can reach more than 2000 times, and the standard charge (5 hour rate) can reach 2000 times. Lead-acid batteries of the same quality are "new for half a year, old for half a year, and maintained for half a year", which is 1 to 1.5 years at most, while a 10kwh LiFePO4 battery china is used under the same conditions, and its theoretical life will reach 7 to 8 years. Considering comprehensively, the performance-price ratio is theoretically more than 4 times that of lead-acid batteries. High current discharge can quickly charge and discharge high current 2C. Under the special charger, the battery can be fully charged within 40 minutes after charging at 1.5C, and the starting current can reach 2C, while lead-acid batteries do not have this performance.
