With　the　rapid　growth　of　the　demand　for　lithium-ion　battery　(LIBs),　a　large　number　of　waste　LIBs　will　be　produced.　If　not　disposed　of　properly,　it　will　bring　serious　environmental　pollution　problems.　The　cathode　materials　of　spent　LIBs　contain　a　large　number　of　rare　valuable　metals,　and　the　recovery　of　these　metals　will　produce　both　environmental　and　economic　benefits.　Compared　with　the　traditional　separation,　purification　and　recovery　technologies　of　metal　components　from　cathode　materials,　the　strategy　of　direct　regeneration　of　cathode　materials　has　attracted　much　attention　due　to　its　advantages　of　simple　process,　low　energy　consumption,　short　recycling　cycle　and　high　added　value　of　products.　Six　direct　regeneration　technologies　for　cathode　materials　from　spent　LIBs　such　as　coprecipitation　method,　sol-gel　method,　solid　phase　sintering　method,　hydrothermal　method,　ion　thermal/molten　salt　method　and　electrochemical　repair　method　were　reviewed　and　their　advantages　and　disadvantages　were　also　summarized.　Among　them,　coprecipitation　method　and　sol-gel　method　had　some　limitations　in　industrial　application　because　of　their　relatively　complex　steps,　high　equipment　requirements　and　reagent　cost.　Solid　phase　sintering　method,　hydrothermal　method,　ion　thermal/molten　salt　method　and　electrochemical　repair　method　had　great　opportunities　for　development　because　of　their　convenience　and　economy.　In　addition,　the　prospect　and　development　trend　of　direct　recycling　of　cathode　materials　from　spent　LIBs　were　prospected　in　order　to　provide　reference　for　the　research　in　the　field　of　spent　LIBs　recycling.　©　2024　Chemical　Industry　Press　Co.,　Ltd..　All　rights　reserved.
