Synthesis and electrochemical properties of layered Li[NixCo1-2xMnxO2] materials for lithium secondary batteries prepared by mechanical alloying

초록

Layered Li[NixCo1-2xMnx]O2 materials with high homogeneity and crystallinity were synthesized using a mechanical alloying method. The Li[Ni0.475Co0.05Mn0.475]O2 electrode delivers a high discharge capacity of 187 mAh/g between 2.8 and 4.6V at a high current density of 0.3mA/cm3 with excellent cyclability.
