Recycling method of cathode material for decommissioned lithium iron phosphate batteryLithium-ion power battery cathode materials include lithium cobaltate, lithium manganate, lithium nickelate, lithium iron phosphate and ternary materials.

Lithium battery is a kind of positive and negative material made of lithium metal or lithium alloy. Lithium batteries are widely used in mobile phones, computers, mobile devices and other electronic products. With the continuous replacement of electronic products, the number of scrapped lithium batteries is increasing. The larger the size, the waste lithium batteries contain some metal materials, all of which have high recycling value.

The main purpose of recycling lithium batteries is to extract metals from cathode materials.

JB Straubel, CEO of Redwood materials and former chief technology officer of Tesla, said at a hearing in the US Senate that his company has recovered about 6gwh of discarded lithium-ion batteries every year.

The purpose of waste lithium battery recycling is to effectively solve the environmental problems caused by the rapid development of lithium batteries, produce significant environmental benefits, and realize the resource recovery of valuable components in waste lithium batteries, so as to produce significant social and economic benefits.
