How to recycling retired lithium batteries？
Release Time：2022-11-17 Source：Battery Recycling Machine Share：
Power lithium-ion battery life is usually 8-10 years, these lithium-ion batteries after 10 years of use will face the problem of decommissioning. Starting from the promotion and popularization of new energy vehicles in 2013, a large number of power batteries will be retired after 2021. How to these retired lithium batteries recycling, how can we exhaust the resources to use them? The retired power battery still has 80% of the battery storage capacity, and this electricity cannot support the use of new energy vehicles. This kind of retired power battery will usually be used in two forms of resource utilization, namely, secondary use and dismantling and crushing to recover valuable metals.
Power battery professional dismantling recycling sorting system equipment processing process
The charged lithium battery is dismantled by oxygen depleted crushing under inert gas protection, closed air discharge, oxygen depleted thermal volatilization, magnetic wind selection and other processes to sort out iron, plastic shell, stainless steel, copper, aluminum, plastic film, volatile electrolytic gas into the combustion system for combustion treatment, the separated pole piece is sent into the cracking system, various waste gases and gas into the combustion system for heating, after cracking the pole piece is cooled, friction de-powdering, screening, specific gravity sorting, dust removal, etc. The waste lithium battery professional disassembly and recycling sorting process separates the pole powder, copper particles and aluminum particles, and the combustion exhaust gas is discharged through cooling, alkali spraying, water spraying and aerosol separation.
Power battery professional disassembly recycling sorting system equipment disassembly equipment for new energy power batteries containing copper and aluminum metal, positive and negative active materials, plastic diaphragm can achieve resource recovery, to achieve the industrialization of waste power batteries, lithium-ion battery processing standardization, industrialization, improve the recycling rate of retired lithium batteries, reduce the environmental pollution caused by not dealing with batteries, incorrect treatment of retired batteries. Practical new energy power battery disassembly and sorting equipment for power batteries, retired lithium batteries, new energy lithium-ion battery positive and negative material utilization rate improvement, copper and aluminum metal and plastic diaphragm sorting rate is also hit to 99%. A complete set of power battery disassembly and sorting equipment processing process equipment flow line to achieve sustainable development of new energy power batteries, so the waste retired lithium-ion battery disassembly crushing separation sorting recovery of new energy power battery in the positive and negative piece of metal utilization prospects are promising.
