摘要

Layered lithium manganese-rich oxides are promising cathode materials for lithium-ion batteries(LIBs),due to the low-cost,abundant manganese source,and large theoretical capacity.How-ever,these layered lithium manganese-rich oxides,e.g.,monoclinic-LiMn02,suffer from poor cycle performance and rate performance because of fast structural degradation with the irre-versible layered-to-spinel phase transition and sluggish electrode kinetics during cycling[1,2].
