Manganese-based　compounds　have　been　regarded　as　the　most　promising　cathode　materials　for　rechargeable　aqueous　zinc-ion　batteries　(AZIBs)　due　to　their　high　theoretical　capacity.　Unfortunately,　aqueous　Zn–manganese　dioxide　(MnO2)　batteries　have　poor　cycling　stability　and　are　unstable　across　a　wide　temperature　range, severely　limiting their　commercial　application.　Cationic　preinsertion　and　defect　engineering　might　increase　active　sites　and　electron　delocalization,　which　render　the　high　mobility　of　the　MnO2　cathode　when　operated　across　a wide　temperature　range.　In　the　present　work,　for　the　first　time,　we　successfully　introduced　lithium　ions　and　ammonium　ions　into　manganese　dioxide　(LNMOd@CC)　by　an　electrodeposition　combined　with　low-temperature　calcination　route　using　spent　lithium　manganate　as　a　raw　material.　The　obtained　LNMOd@CC　exhibits　a　high　reversible　capacity　(300　mAh　g−1　at　1　A　g−1)　and　an　outstanding　long　lifespan　of　over　9000　cycles　at　5.0　A　g−1　with　a　capacity　of　152　mAh　g−1,　which　is　significant　for　both　the　high-value　recycling　of　spent　lithium　manganate　batteries　and　high-performance　modification　for　MnO2　cathodes.　Besides,　the　LNMOd@CC　demonstrates　excellent　electrochemical　performance　across　wide　temperature　ranges　(0–50°C).　This　strategy　simultaneously　alleviates　the　shortage　of　raw　materials　and　fabricates　electrodes　for　new　battery　systems.　This　work　provides　a　new　strategy　for　recovering　cathode　materials　of　spent　lithium-ion batteries　and　designing　aqueous　multivalent　ion　batteries.　©　2023　The　Authors.　Battery　Energy　published　by　Xijing　University　and　John　Wiley　&　Sons　Australia,　Ltd.
