Optimized electrochemical performance of Ni rich LiNi_0.91Co_0.06Mn_0.03O₂ cathodes for high-energy lithium ion batteries.

ABSTRACT: We report high electrochemical performances of LiNi_0.91Co_0.06Mn_0.03O₂ cathode material for high-energy lithium ion batteries. LiNi_0.91Co_0.06Mn_0.03O₂ is synthesized at various sintering temperatures (640~740 °C). The sintering temperatures affect crystallinity and structural stability, which play an important role in electrochemical performances of LiNi_0.91Co_0.06Mn_0.03O₂. The electrochemical performances are improved with increasing sintering temperature up to an optimal sintering temperature. The LiNi_0.91Co_0.06Mn_0.03O₂ sintered at 660 °C shows remarkably excellent performances such as initial discharge capacity of 21
