Due　to　the　abundant　reserves　of　Fe　and　Mn,　the　Fe–Mn　based　cathode　material　have　attracted　much　attention　as　electrode　materials　for　next　generation　lithium　ion　batteries.　In　order　to　keep　the　high　activity　and　improve　the　stability　of　the　nanoparticles,　the　spherical　Li1.26Fe0.22Mn0.52O2　is　assembled　by　spray　granulation　method　with　nano-precursor　prepared　by　molten　salt　method.　The　granulated　spheres　have　a　higher　specific　discharge　capacity　197　mAh　g−1　at　0.2C　than　that　of　nanoparticles　obtained　by　simple　molten　salt　method.　The　granulated　spheres　also　exhibit　a　distinctly　improved　cycle　stability　and　rate　performance.　Moreover,　the　tap　density　of　granulated　spheres　increases　and　their　specific　surface　area　decreases　obviously,　indicating　that　the　primary　particles　contact　closely　and　particle＇s　contact　area　with　electrolyte　reduces.　Therefore,　particle　granulation　avails　to　balance　material＇s　activity　and　stability.　In　addition,　the　micron-spherical　particles　are　beneficial　to　make　electrode　fabrication　easier　and　increase　the　specific　energy　density　of　batteries.　©　2021　Elsevier　Inc.
