Lithium iron phosphate batteries have poor performance at low temperatures. The life of a single lithium iron phosphate battery is long, about 2,000 times, but the life of a lithium iron phosphate battery is short, generally about 500 times.
Lithium iron phosphate batteries have poor electrical conductivity and slow diffusion of lithium ions. When charged and discharged at high times, the actual specific capacity is low.
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the positive electrode material.
The lifespan of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the lifespan of lithium iron phosphate batteries reaches more than 2,000 times when used with standard batteries. When charging (5 hours rate), it can reach 2000 times.
The P-O bond in lithium iron phosphate crystal is stable and not easy to decompose, even at high temperatures or overload, it will not collapse and generate heat nor will it form strong oxidizing substances like lithium cobalt oxide. good security.
It has been reported that in actual operation, a small number of samples burned during acupuncture or short circuit experiments, but there were no explosion incidents in the experience of overcharging, a battery that has far exceeded. its own discharge voltage has been used several times. After high voltage charging, it was found that there was still an explosion. Despite this, its overcharge safety has been significantly improved compared to ordinary liquid electrolyte, lithium and cobalt oxide batteries.
