摘要
Abstract
Carbon coated lithium iron phosphate (LiFePO4/C) and Zinc(Zn) doped LiFePO4/C were synthesized via co-precipitation method.The sample LiFe0.67Zn0.33PO4 had the olivine structure,the particle diameter was 0.04～47.90 μm.The doping of Zn reduced crystal size,increased the conductivity and Li+ diffusion rate. When the sample cycled 50 times with 0.2 C,0.5 C and 1.0 C in 2.0～4.2 V,its capacity retention rate was 95.2% , 82.9% and 79.9% ,respectively. 关键词
