废旧磷酸铁锂电池正极材料直接修复再生研究进展
Research progress on direct remediation and regeneration of cathode materials from spent lithium iron phosphate batteries
摘要
Abstract
In recent years,as the production of electric vehicles climbs,the consumption of lithium-ion batteries has increased dramatically,and a large number of end-of-life batteries have brought about various environmental and resource problems.Therefore,the treatment and recycling of spent lithium-ion batteries have become an urgent problem.Lithium iron phosphate(LFP)batteries have become one of the mainstream lithium batteries used in electric vehicles due to their high stability and high cycle life.However,the existing LFP recycling methods are complicated and polluting,and the recycled products are mostly alloys or metal salts,which can only be used as battery precursors.In contrast,the direct repair and regeneration of spent LFP cathode materials have many advantages,such as short process,simple method,low energy consumption,low emission,etc.,which is in line with the current dual-carbon goal of China.This paper summarized the latest research progress of direct repair and regeneration of spent LFP cathode materials,including the research status of direct repair and regeneration methods such as solid-phase sintering,hydrothermal method and electrochemical method,and analyzed and compared the advantages and shortcomings of various methods.Finally,the application challenges and development prospects of direct repair and regeneration of spent LFPs were analyzed from multiple perspectives to provide references and suggestions for the research on efficient recycling of spent LFPs.关键词
