Effect of Different Carbon on the Properies of LiFePO_4/C

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.
