Doped olivine LiMPO4 (M = Mn/Ni) derivatives as potential cathode materials for Lithium-ion batteries: a mini review

摘要

Olivine LiMPO4 (M = Mn, Ni) cathode materials are being widely explored as potential cathode materials for lithium-ion batteries due to its good structural properties, high potential, and specific capacity reaching similar to 170 mAh g(-1). Nevertheless, these cathode materials suffer poor electronic and ionic conductivity, stumbling its application in electrochemical devices. Thus, phospho-olivine cathodes research and development are continuously being studied directly proportional to its advanced applications. Among the various modifications to overcome the deficiency, this mini review explains the doping technique in LiMPO4 (M = Mn, Ni) cathode materials. Consequently, enhanced performances are discussed based on physical and electrochemical characteristics as well as a scalable application route.
