Based on global patent data in the field of lithium iron phosphate battery recycling technology,this paper studies the overall development trend of lithium iron phosphate battery recycling technology through patent information analysis,and the technological evolution path of the five technical branches of pre－treatment process,discharge process,disassembly process,positive and negative electrode material separation process and regeneration process.The research results show that domestic related technologies are currently in a period of rapid growth,and China's dominant technology direction is re-generation process and disassembly process,the United States and Japan's dominant technology direc-tion is regeneration process,and South Korea's dominant direction is focused on regeneration process and positive and negative electrode material separation process.The current blank technology is the supporting equipment of the five processes and the related technology of the four processes in addition to the regeneration process.On this basis,combined with the blank technology,the patent layout sug-gestions are given.
