Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in the vast majority of lithium-ion batteries. In terms of material principle, lithium iron phosphate is also an intercalation and deintercalation process, which is exactly the same as lithium cobaltate and lithium manganate. Lithium iron phosphate battery is a lithium ion secondary battery, one of the main uses is for power batteries, which has great advantages over NI-MH and Ni-Cd batteries. The charge and discharge efficiency of lithium iron phosphate batteries is high, and the charge and discharge efficiency can reach more than 90% under the rate discharge condition, while the lead-acid battery is about 80%....

The decommissioned lithium iron phosphate batteries and the batteries after the cascade use that do not have the value of cascade use will eventually enter the dismantling and recycling stage. The difference between a lithium iron phosphate battery and a ternary material battery is that it does not contain heavy metals, and the main recovery is Li, P, and Fe. The added value of recycled products is low. Need to develop a low-cost recovery route, there are mainly two recovery methods, fire method and wet method. 1. Fire recovery process The traditional fire method generally burns the electrode sheet at a high temperature to burn off the carbon and organic matter in the electrode sheet. The remaining incombustible ash is finally screened to obtain fine powder materials containing metals and metal oxides. The process is simple, but the treatment process is long, and the comprehensive recovery rate of valuable metals is low. The improved fire recovery technology is to remov...

Lithium iron phosphate batteries are used to make lithium-ion secondary batteries. Nowadays, the primary direction is power lithium-ion batteries, which have great advantages compared to NI-H and Ni-Cd batteries. Seven advantages of lithium iron phosphate power lithium ion battery: 1. Super long life. The life of a long-life lead-acid battery is about 300 cycles, up to 500 cycles. Lead-acid batteries of the same quality are new for half a year, old for half a year, repaired and maintained for half a year, that is, more than 1.5 years, while lithium iron phosphate batteries can be used for 7-8 years under the same conditions. Overall, the cost performance is more than 4 times that of lead-acid batteries. 2. Safe to use. Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganate. Lithium cobalt oxide and lithium manganese oxide will explode in a violent collision, posing a threat to consumers' lives, while lithium iron ...
