Abstract

The invention discloses a waste power battery single body full-component recovery system which comprises a single body discharge system, a crushing system, an electrolyte recovery system, a diaphragmrecovery system, a cracking system, a tail gas purification system and a separation system. Electrolyte, diaphragm paper, battery powder and metal materials in batteries can be recovered in a full-component manner. The waste power batteries are subjected to working procedures of discharge, crushing, electrolyte recovery, diaphragm paper recovery, cracking, separation and the like to obtain final products. All the working procedures of the whole system are connected in a head and tail manner, continuous production can be achieved, material circulation is reduced, and labor and consumption costare reduced remarkably. The batteries can be recovered in a full-component manner. The batteries are crushed after being discharged, and the technology is safe and reliable. After diaphragms and the electrolyte in battery crushed materials are removed, then the cracking technology is adopted for treating the battery crushed materials, the cracking reaction is easier, the problem of material bonding caused by diaphragm melting is effectively avoided, and powder of positive and negative anodes of the batteries are separated more thoroughly.

Description

technical field [0001] The invention relates to the field of lithium battery recovery systems, in particular to a recovery system for all components of waste power battery monomers. Background technique [0002] Since 2017, the average energy density of battery packs for pure electric passenger vehicle products in the Chinese market has increased significantly every year, reaching an overall high level of 144.07Wh / kg by 2019. In addition, the report of the China Electric Vehicle 100 "Power Battery Lifecycle Assets Operation Management" project report shows that after 2018, my country's new energy vehicle power batteries will enter a large-scale scrapping period, and it is estimated that the amount of scrapping will reach 480,900 tons in 2023. A large number of waste power lithium batteries are produced. Since the waste batteries contain the valuable metal nickel-cobalt-manganese-lithium, they have great recycling value. [0003] The waste power battery monomer is composed of...
