Abstract

用流变相法制备了ZnO修饰Fe 1.5 P电极材料, 用X射线衍射仪对产物进行成分分析, 用透射电镜表征形貌, 用恒流充放电法、循环伏安法和电化学阻抗谱法研究了ZnO修饰对Fe 1.5 P电化学性能的影响. 实验结果表明: ZnO修饰能够提高Fe 1.5 P的倍率特性, 使Fe 1.5 P的首次放电容量提高~69.7%, 达到837.5 mAh/g, 经过215次循环后, 将Fe 1.5 P在12 C倍率下的放电容量提高~144.3%, 而且将Fe 1.5 P在0.1 C倍率下的恢复放电容量提高~330%; 另外, ZnO修饰Fe 1.5 P的SEI膜阻抗 R SEI 、电荷传递阻抗 R d 和Li + 扩散的Warburg阻抗Wb分别降低~87.9%、~87%和~13.2%, 将锂离子扩散系数提高~86.6%.
