The　power　lithium　ion　battery　has　been　widely　used　for　its　excellent　performance,　with　the　waste　batteries　increased　yearly　and　causing　environmental　pollution　and　resource　waste.　The　problem　must　be　solved　immediately.　In　this　paper,　through　the　＂alkaline　separation-roasting-acid　leaching＂　process,　spent　lithium　ion　battery　anode　is　handled　so　that　to　achieve　the　extraction　of　valuable　metals　in　the　anode.　The　results　show　positive　active　material　can　separate　from　the　aluminum　foil　by　means　of　the　using　of　NaOH　solution.　Under　the　process　of　700　degrees　C　high-temperature　roasting　for　2　h,　active　substances　Li　(NixCo1-x)　O-2　transform　into　NiO,　CoO,　etc.,　and　it　is　conducive　to　subsequent　acid　leaching.　After　roasting,　the　acid　leaching　of　active　substance　is　conducted　through　respectively　using　hydrochloric　acid　and　sulfuric　acid.　The　leaching　rate　of　Li,　Ni,　Co　are　99.9,　99.5,　99.2%　under　the　optimum　conditions　in　hydrochloric　acid　system　respectively:　the　concentration　of　the　acid　2　mol/L,　the　ratio　of　solid-liquid　60　mg/ml,　leaching　temperature　90　degrees　C　and　leaching　time　50　min.　In　sulfuric　acid　system,　the　leaching　rate　of　Li,　Ni,　Co　are　all　closer　to　100%　under　the　optimum　conditions:　the　concentration　of　the　acid　2　mol/L,　the　S/L　75　mg/ml,　leaching　temperature　85　degrees　C　leaching　time　50　min　and　volume　ratio　of　hydrogen　peroxide　is　5%.　Through　the　fitting　calculation,　acid　leaching　is　applied　to　the　nuclear　reaction　model　and　leaching　of　lithium　nickel　and　cobalt　are　controlled　by　chemical　reaction.　Two　kinds　of　acid　system　all　have　good　results　for　metal　extraction　from　waste　lithium　ion　battery　cathode　material.　Considering　recycling　cost　and　environmental　impact,　sulfuric　acid　system　is　better.
