Abstract: Lithium ion batteries are green,highenergy,and chargeable cells,which have predominant advantages,such as high working voltage,high specific capacity,low local action,long cycle life,nomemory effect,and nonenvironmental pollution.In recent years,spinel lithium manganate as cathode material has attracted wide attention due to its nontoxic,low cost,and high specific capacity etc..However,it has a main problem related to quick capacity fading at high temperature,which prohibited its largescale application.Research progress in recent years on  preparation and modification of lithium manganate cathode material was introduced,and based on that,the major developing trend was prospected.
