Abstract : The cathode materials for lithium ion battery have been developed in accordance with the battery performance. LiCoO 2 initially adapted at lithium ion battery is going to be useful even at the charging voltage of 4.3 V by surface treatment or doping which drastically improved the performance of LiCoO 2. On the other hand, the complicate and multiple functions of recent electronic equipments required higher operational voltage and higher capacity than ever, which is going to be driving force for developing new cathode materials. Some of them are LiNi 1 xm x O 2, Li[Ni x Mn y Co z, Li[Ni 1/2. Other new type of cathode materials having high safety is also developed to apply for HEV (hybrid electrical vehicle) and power tool applications. LiMn 2 and LiFeP are famous for highly stable material, which are expected to give contribution to make safer battery. In near future, the various materials having both capacity and safety will be developed by new technology, such as solid solution composite.
