混合铁源制备碳包覆磷酸铁锂
Preparing carbon coated lithium ferrous phosphate using mixed iron sources
摘要
Abstract
Carbon coated lithium ferrous phosphate(LiFePO4/C)as cathode material of Li-ion battery was synthesized by solid state reaction method using mix iron sources. The surface morphology,crystal structure and the electrochemical performance were charac-terized by SEM,XRD,charge-discharge testing and electrochemical impedance spectra(EIS). The composite synthesized at 700 ℃with mixed iron sources n(FeC2 O4·2H2 O)∶n(FePO4 )=1∶1 had better electrochemical performance,when charged-discharged in 2.5 ~4.1 V,the 0.2 C specific discharge capacity was 165.9 mAh/g,the specific discharge capacity in the initial and 20th cycle at 2.0 C was 135.3 mAh/g and 141.9 mAh/g,respectively.关键词
