复合球形LiFePO4/C的合成与电化学性能
Synthesis and electrochemical performance of ball-in-ball structure LiFePO4/C
摘要
Abstract
LiFePO4/C was synthesized by hydrothermal synthesis method using P123 (EO20PO70EO20)as template.The structure and morphology of the material were analyzed by XRD and SEM tests.Electrochemical performance of the material was studied by galvanostatic charge-discharge and cyclic voltammetry tests.The sample was pure phase LiFePO4 and had a structure of ball-in-ball When charged-discharged in 2.7 ～4.2 V,the 0.1 C and 10.0 C specific discharge capacity was 159 mAh/g and 93 mAh/g,respectively.When cycled in the order of0.1 C,0.5 C,1.0 C,2.0 C,10.0 C and 0.1 C for20 cycles in each current,it had no evident capacity fading after 120 cycles.关键词
