Generally, the optimization of synthesis conditions has great influence on the properties of the electrode materials for lithium-ion batteries (LIBs). Nowadays, Li-rich manganese-based cathode materials with high capacity are still suffering from low first charge/discharge capacity and poor high-rate capability. In this work, Li[Li[Formula: see text]Fe[Formula: see text]Ni[Formula: see text]Mn[Formula: see text]]O2 has been successfully synthesized by hydroxide co-precipitation method, and the effect of calcination temperature on the material characteristics and electrochemical performance has been investigated. The results show that with the increase of calcination temperature, the layered structure of Li-rich material becomes better. When the calcination temperature is 800[Formula: see text]C, the prepared material exhibits the most excellent electrochemical properties, including high first charge/discharge specific capacity of 366.6/251.9 mAh g[Formula: see text] and good high-rate capability. It is expected that the results of this study can lay a solid foundation for the subsequent research on the modification of this material.
