主要研究了采用不同碳源和掺碳量包覆对液相共沉淀-碳热还原法制备的球形LiFePO4材料性能的影响.结果表明,采用过量5%葡萄糖作碳源制备的材料在0.1C下,首次放电比容量达到了154.6mAh/g,并且循环性能良好.
The researched the modification by coating spherical LiFePO4 materials prepared by co-deposited-car-bonthermal reduction with different carbon sources and mixing accounts. The result indicated that the samplecoated with 5 % excess glucose has the most optimized electrochemical properties with a discharge capacity of 154.6mAh/g under a current density of 0. 1C and good cycle performance.
