主要研究了采用不同碳源和掺碳量包覆对液相共沉淀一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-carbonthermal reduction with different carbon sources and mixing accounts. The result indicated that the sample coated 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.
