The　practical　application　of　graphite　cathodes　in　aluminum　ion　batteries　(AIBs)　is　hindered　by　poor　cycle　and　rate　performance　of　graphite,　due　to　serious　structural　degradation.　In　this　work,　different　types　of　kish-expanded　graphite　(KEG)　with　different　expansion　volumes　were　prepared　simply　and　rapidly　using　low-cost　solid　waste　kish　graphite　(KG)　as　precursor,　and　K2S2O8　and　concentrated　H2SO4　as　oxide　intercalation　agents　by　spaceconfined　intercalation　expansion　strategy.　By　adjusting　the　mass　ratio　of　K2S2O8　to　KG,　the　macrostructure　and　microstructure　of　KEG　can　be　effectively　controlled.　Specifically,　KEG6,　synthesized　with　the　mass　ratio　of　K2S2O8　to　KG　of　6,　exhibited　a　large　expansion　volume,　graphene　nanosheets　with　numerous　graphite　microcrystalline　layer　structures,　and　micro-nano　interlayer　pore　structures　resulting　from　the　cross-linking　of　graphene　nanosheets,　along　with　abundant　oxygen-containing　functional　groups.　KEG6,　as　a　cathode　material　for　AIBs,　exhibited　outstanding　electrochemical　performance,　including　superior　specific　capacity　(141.1　mA　h/g　at　50　mA/g),　good　rate　capability　(119.8　mA　h/g　at　1000　mA/g,　85.6　mA　h/g　at　2000　mA/g)　and　remarkable　cycle　stability　(134.0　mA　h/g　with　99.1%　Coulombic　efficiency　after　10,000　cycles　at　1000　mA/g).　This　study　provides　a　simple　and　rapid　method　for　the　large-scale　synthesis　of　KEG　as　a　potential　candidate　for　AIBs.
