Nowadays, many researchers have been studying on the layered rock salt-type structure as cathode materials for the lithium ion batteries. LiCoO2is the most commonly used cathode material but Co is costly and toxic. Thus, alternative cathode materials which are cheaper, safer and having higher capacity are required. Replacing Co with Ni offered higher energy density battery but it raised interlayer mixing or cation disorder that impedes electrochemical properties of batteries. This paper has reviewed some recent research works that have been done to produce better and safer cathode materials from the structural perspective.

LiMn1-xFexPO4 cathode materials were synthesized by microwave hydrothermal using ascorbic acid as reducing agent. The crystal structure, microstructure, electrochemical properties were characterized by XRD and SEM, the discharge capacity and cycling performance were compared. The results show that the lattice parameters of LiMnPO4 decreased by doping Fe, and the doping amount is x = 0.4, the discharge capacity of the prepared material reaches to 145 mAh/g, which has improved of 76.8% compared with the undoped LiMnPO4 at 0.1C.
