The　recovery　of　spent　graphite　(SG)　from　lithium-ion　batteries　(LIBs)　has　been　neglected　due　to　its　relatively　low　value　and　the　lack　of　effective　recovery　methods.　In　this　study,　a　green　and　cost-effective　water　washing　process　was　used　to　recycle　the　spent　graphite　of　LIBs　anode,　and　the　recovered　graphite　(RG)　was　used　as　the　cathode　material　of　aluminum　ion　batteries　(AIBs).　The　RG　retained　the　integrated　graphite　structure　after　the　water　washing　process,　showing　a　slightly　enlarged　interlayer　spacing.　When　used　as　a　cathode　material　for　AIBs,　it　exhibits　better　electrochemical　performance　than　commercial　artificial　graphite.　At　a　current　density　of　50　mA　g−1,　the　RG　shows　a　high　specific　capacity　of　95.2　mAh　g−1.　At　a　high　current　density　of　2000　mA　g−1,　the　specific　capacity　still　maintains　51　mAh　g−1,　demonstrating　excellent　rate　performance.　Meanwhile,　the　average　specific　capacity　of　72.5　mAh　g−1　was　steadily　cycled　for　10,000　cycles　at　a　current　density　of　1000　mA　g−1,　showing　excellent　cycle　performance.　This　work　provides　a　novel　approach　to　the　high-value-added　application　of　spent　graphite　from　lithium　batteries　and　a　development　of　high-performance　graphite　cathode　materials　for　AIBs.　©　2024
