The Effect of Thermal Treatment Temperature and Duration on Electrochemistry Performance of LiNi1/3Co1/3Mn1/3O2 Cathode Materials for Lithium-Ion Batteries

摘要

Background: LiNi1/3Mn1/3Co1/3O2 derived from the solid-state method suffers from the problem of significant irreversible charge-discharge behavior. To improve the electrochemical performance of LiNi1/3Mn1/3Co1/3O2, there are several important factors, such as starting raw materials, precursor, preparation method and conditions. In this work, the layered LiNi1/3Mn1/3Co1/3O2 material was prepared by solid-state reaction. By varying the temperature and duration of synthesis thermal treatment, the greater crystallinity and well-ordered layered LiNi(1/3)Mn(1/3)Co(1/3)O(2)cathode material has been successfully synthesized. The structural properties, morphology and electrochemical properties of LiNi1/3Mn1/3Co1/3O2 powders have been investigated in detail.
