摘要
Abstract
Three-dimensional porous structure lithium iron phosphate (LiFePO4) electrode using nickel foam as current collector was prepared to improve the high-rate ability of LiFePO4. Three-dimensional porous structure LiFePO4 electrode had better high-rate charge-discharge ability compared to a conventional LiFePO4 electrode using aluminum foil as current collector, when discharged in 2.5 ~ 3.8 V with the current of 5.0 C,the specific capacity was 101.7 mAh/g.The results of cyclic voltammetry and AC impedance tests indicated that the using of three-dimensional structure current collector decreased the electrochemical reaction polarization of LiFePO4 electrode.关键词
