We successfully synthesized a single crystal LiNi0.91Co0.06Mn0.03O2 via heat-treatment and measured its electrochemicalperformances. The structural characterizations and electrochemical properties of single crystal LiNi0.91Co0.06Mn0.03O2 arestudied in order to apply to lithium-ion batteries for electric vehicles. The crystallization and morphology of the sample aremeasured by XRD, SEM. An initial discharge capacity of single crystal LiNi0.91Co0.06Mn0.03O2 is 202.1 mAh g1. Also it exhibitssuperior capacity retention of 89.7% under high current density of 4.0 C, which are higher electrochemical performances ascompared to previously reported polycrystalline sample. Therefore, we can conclude that single crystal LiNi0.91Co0.06Mn0.03O2can be regarded as an effective way for next generation cathode candidate.
