研究了PVB、β-环糊精为碳源,对制备的LiFePO4为锂离子电池正极材料时的性能的影响.结果表明:PVB、β-环糊精对LiFePO4的晶体结构没有影响,PVB为碳源制备的LiFePO4的颗粒粒径要比β-环糊精的小,导电性能、大电流充放电性能和循环性能更好.
Research the effect on the Lithium-ion battery cathode material performance that prepared by LiFePO4 with PVB,β-cyclodextrin as carbon source was researched.The results show that,PVB,β-cyclodextrin have no effect on crystal structure of LiFePO4,the particle size of LiFePO4 which prepared by the carbon source PVB is smaller than the carbon source β-cyclodextrin,and has better conductive performance,high-current charge-discharge performance and cycle performance.
