The LiFePO4 battery has the advantages of high working voltage, large energy density, long cycle life, good safety performance, small self-discharge rate, and no memory effect. ① The working voltage is high. The operating voltage of the lithium cobaltate lithium ion battery is 3.6V, the operating voltage of the lithium manganate lithium ion battery is 3.7V, the operating voltage of the lithium iron phosphate battery pack is 3.2V, and the operating voltage of the nickel-hydrogen and nickel-cadmium batteries is only 1.2V. ② High energy density. The theoretical energy density of the lithium battery pack cathode material can reach more than 200W · h / kg. In practical applications, due to irreversible capacity loss, the energy density is usually lower than this value, but it can reach 140W · h / kg, which is still nickel-cadmium. 3 times the battery and 1.5 times the NiMH battery. ③Long cycle life. At present, the lithium battery pack can be cycled more than 1,0...
