The　number　of　spent　LiFePO4　batteries　has　increased　with　the　rapid　development　of　the　electric　vehicle　industry　in　China.　Recycling　of　spent　LiFePO4　batteries　is　important　not　only　for　the　treatment　of　waste　but　also　for　the　recovery　of　useful　resources.　However,　the　treatment　of　spent　LiFePO4　batteries　is　challenging　because　LiFePO4　batteries　do　not　contain　any　precious　metals,　treatment　is　complex　using　traditional　recycling　process,　and　the　number　of　spent　batteries　recovered　from　the　public　has　been　very　small　recently.　Therefore,　it　is　necessary　to　summarize　the　existing　problems　and　propose　a　proper　recycling　route　for　spent　LiFePO4　batteries.　In　this　paper,　the　current　status　of　spent　LiFePO4　batteries　recycling　in　China　is　introduced,　and　the　environmental　benefits　of　recycling　are　analyzed.　The　state　of　the　art　in　preprocessing　of　End-of-Life　LiFePO4　batteries　and　the　final　batteries　recovery　is　discussed　in　detail.　Based　on　the　review,　optimizing　the　recycling　mode,　increasing　the　precious　metals　recovery　efficiency,　and　decreasing　the　chemical　reagents　consumption　by　effective　materials　liberation　and　separation　are　proposed　as　potential　improvement　strategies　to　make　the　recycling　chain　more　environmentally　friendly.
