Lithium iron phosphate battery refers to lithium ion battery with lithium iron phosphate as positive electrode material. The anode materials of lithium ion battery mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, lithium iron phosphate and so on. At present, lithium cobalt oxide is the anode material used in most lithium ion batteries.
Safety improvements made by lithium iron phosphate battery manufacturers: the p-o bond in lithium iron phosphate crystals is stable and difficult to be decomposed. Even at high temperature or over charge, it will not 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 of acupuncture or short circuit experiment, a small part of samples were found to have combustion phenomenon, but there was no explosion event. However, in the overcharge experiment, a high voltage charge that was several times higher than its own discharge voltage was used, and explosion phenomenon was still found. Nevertheless, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt battery.
Life improvement of lithium iron phosphate battery manufacturers: lithium iron phosphate battery refers to lithium ion battery with lithium iron phosphate as the positive electrode material. Long life lead-acid battery cycle life of 300 times or so, the highest is 500 times, and lithium iron phosphate power battery cycle life of more than 2000 times, the standard charge (5 hours rate) use, can reach 2000 times. Lead-acid battery of the same quality is "new half year, old half year, maintenance and maintenance of half a year", the most is 1~1.5 years, and lithium iron phosphate battery in the same condition, the theoretical life will reach 7~8 years. Overall, the performance price is more than 4 times of the theoretical lead-acid battery. Large current discharge can be large current 2C quick charge and discharge, in the special charger, 1.5C charge can make the battery full within 40 minutes, starting current up to 2C, but lead-acid batteries do not have this performance.
