P123辅助合成的Li3V2(PO4)3/C的电化学性能
Electrochemical performance of Li3V2(PO4)3/C synthesized with P123 assisted
摘要
Abstract
Sub-micron Li3V2(PO4)3/C was synthesized by solution-phase method,CH3COOLi, V2O5,H3PO4,oxalic acid and surfactant P123(EO20PO70EO20) were used as raw materials. The effects of calcining temperature to the products were studied by XRD,SEM and electrochemical analyses.The particle size of Li3V2(PO4)3/C synthesized with P123 assisted was smaller and its electrochemical performance was improved. The crystal of synthesized Li3V2(PO4)3/C calcining under 850 ℃ grew perfectly,its reversibility was the best,the charge transfer resistance was lowest.The initial specific discharge capacity was 128.7 mAh/g under 0.1 C in 3.0~4.3 V, the 5.0 C specific discharge capacity was 104.3 mAh/g, the capacity retention ratio was 81 % .关键词
