废旧锂离子电池磷酸铁锂正极材料直接再生的研究现状
Research status of direct regeneration of spent lithium iron phosphate batteries
摘要
Abstract
In recent years,the recycling and treatment of waste lithium ion batteries and lithium iron phosphate(LFP)cathode materials in the field of new energy have attracted widespread attention.In addition to reducing the pollution of harmful components in waste batteries to the environment,the regeneration of battery materials is also crucial for resource utilization and economic benefits.This ar-ticle reviews the research progress of LFP direct regeneration methods such as solid-phase method,hy-drothermal method,eutectic method,and electrochemical regeneration method.At the same time,it introduces a groundbreaking new LFP regeneration technology.Finally,this article briefly introduces the commercialization process of direct recycling of waste lithium ion battery materials,discusses the advantages and disadvantages of LFP direct regeneration method,and some challenges encountered in the current regeneration process.It also looks forward to the future development of this field,lay-ing a good foundation for further realizing the industrial production of LFP battery recycling.关键词
