Abstract：

The　cobalt-free　Mn-based　Li-rich　layered　oxide　material　has　the　advantages　of　low　cost,　high　energy　density,　and　good　performance　at　low　temperatures,　and　is　the　promising　choice　for　energy　storage　batteries.　However,　the　long-cycling　stability　of　batteries　needs　to　be　improved.　Herein,　the　Mn-based　Li-rich　cathode　materials　with　small　amounts　of　Li2MnO3　crystal　domains　and　gradient　doping　of　Al　and　Ti　elements　from　the　surface　to　the　bulk　have　been　developed　to　improve　the　structure　and　interface　stability.　Then　the　batteries　with　a　high　energy　density　of　600　Wh　kg−1,　excellent　capacity　retention　of　99.7　%　with　low　voltage　decay　of　0.03　mV　cycle−1　after　800　cycles,　and　good　rates　performances　can　be　achieved.　Therefore,　the　structure　and　cycling　stability　of　low　voltage　Mn-based　Li-rich　cathode　materials　can　be　significantly　improved　by　the　bulk　structure　design　and　interface　regulation,　and　this　work　has　paved　the　way　for　developing　low-cost　and　high-energy　Mn-based　energy　storage　batteries　with　long　lifetime.　©　2024
