Influence of sintering temperatures on microstructure and electrochemical performances of LiNi_0.93Co_0.04Al_0.03O₂ cathode for high energy lithium ion batteries.

ABSTRACT: In this study, we present a method for synthesizing Ni-rich LiNi_0.93Co_0.04Al_0.03O₂ (NCA) with a high-energy cathode material by the solid-phase method. The sintering temperature plays a very important role in the electrochemical performance of the LiNi_0.93Co_0.04Al_0.03O₂ since it affects the crystallinity and structural stability. Therefore, various sintering temperatures (660 °C/690 °C/720 °C/750 °C/780 °C/810 °C) are studied to get optimum electrochemical performances. The electrochemical performance of LiNi_0.93Co_0.04Al_0.03O₂ sintered at 720 °C shows the highest discharge capacity of 217.48 mAh g^-1 with excellent Coulombic efficiency of 87.84% at 0
