How to dispose of lithium-ion battery recycling?

The recycling process of waste lithium-ion batteries mainly includes pretreatment, secondary treatment and advanced treatment. Since part of the electricity still remains in the used battery, the pretreatment process includes deep discharge process, crushing, and physical sorting; the purpose of secondary treatment is to achieve complete separation of positive and negative active materials from the substrate. Heat treatment methods and organic solvent dissolution methods are commonly used. , lye dissolution method and electrolysis method to achieve complete separation of the two;

Advanced treatment mainly includes two processes of leaching and separation and purification to extract valuable metal materials; according to the classification of extraction process, battery recycling methods can be mainly divided into three categories: dry recycling, wet recycling and biological recycling.

Lithium-ion battery recycling program

Dry recovery refers to the direct recovery of materials or valuable metals without media such as solutions. Among them, the main methods used for dry recycling are physical sorting and high-temperature pyrolysis. The physical sorting method refers to the dismantling and separation of the battery, and the battery components such as electrode actives, current collectors and battery shells are crushed, sieved, magnetically separated, pulverized and classified to obtain valuable high-content substances. Prepare for the subsequent chemical leaching process;

A lithium battery recycling process, comprising the following steps:

a. First, discharge the lithium battery;

b. Disassemble the lithium battery after the discharge treatment in a;

c. Drain the internal electrolyte of the disassembled lithium battery in b;

d. The lithium battery in c is sent to the sorting and recycling device for crushing and recycling;

The recovery device includes a main body, a motor, a rotating plate, a pulverizing device, a feeding port, a sealing device, a sorting device, a U-shaped groove, a rack, a moving block, a gear, a rotating roller, a filter plate, a pulverizing knife, a drive Mechanism; discharge treatment prevents the waste lithium battery from exploding when it is broken, and improves the safety of lithium battery recycling; the crushing device enables the battery to be screened during crushing, so that the metal powder adhered to the metal can be separated, The battery recycling efficiency is improved; the sealing device can make the battery in a vacuum state during crushing, which improves the security of crushing; further improves the effect of battery recycling.
