Abstract

We successfully synthesized a single crystal LiNi0.91Co0.06Mn0.03O2 via heat-treatment and measured its electrochemical performances. The structural characterizations and electrochemical properties of single crystal LiNi0.91Co0.06Mn0.03O2 are studied in order to apply to lithium-ion batteries for electric vehicles. The crystallization and morphology of the sample are measured by XRD, SEM. An initial discharge capacity of single crystal LiNi0.91Co0.06Mn0.03O2 is 202.1 mAh g-1. Also it exhibits superior capacity retention of 89.7% under high current density of 4.0 C, which are higher electrochemical performances as compared to previously reported polycrystalline sample. Therefore, we can conclude that single crystal LiNi0.91Co0.06Mn0.03O2 can be regarded as an effective way for next generation cathode candidate
