摘要
以不同比例乙二醇水溶液作为溶剂,通过溶剂热法制得LiNi0.5Mn1.5O4正极材料,讨论了不同溶剂对材料的影响,得到溶剂组成对性能影响的规律。水与乙二醇比例为5:1制得的材料电化学性能最佳,在1C倍率条件下首次放电比容量为140.96mAh/g,100次循环后容量保持率仍高达92.96%。
In this paper,the lithium nickel manganese oxides were prepared by solvent thermal method with the mixed solution of ethylene glycol and water of different proportions as the solvent,and the effects of different proportions of solvents on the materials were discussed,so as to obtain the rule of the influence of solvent composition on the properties.The prepared materials with a composition ratio of 5:1 of water and ethylene glycol have the best electrochemical performance.The first discharge specific capacity under the condition of 1C ratio is 140.96 mAh/g,and the capacity retention rate is still as high as 92.96%after 100 cycles.
