Lithium-ion battery disassembly and recycling technology and progress
The extensive use of lithium-ion batteries has generated more and more lithium-ion battery waste,and how to deal with this lithium-ion battery waste in an environmentally friendly,safe and cost-effective manner has become a hot issue in the field.This paper took the hazards and resource utilization value of waste lithium-ion batteries as the background,focused on the process of dismantling and recycling of waste lithium-ion batteries,which included pre-treatment,mainstream recycling methods,metal separation,recovery and recycling,based on the relevant technical principles,It focused on summarizing the progress of academic achievement on the process of recycling of waste lithium-ion batteries mainly by wet recycling in recent years,and analyzed the advantages and shortcomings of each method in the process,followed by a brief introduction to physical recycling and fire recycling.Finally,based on the existing recycling status quo,the future outlook of lithium-ion batteries was made,and reasonable development directions were suggested such as the establishment of a large-scale pretreatment production line,the reuse of recycled materials in adjacent fields and the reuse of chemical reagents.
