摘要 通过固相反应制备了Mg2+和Co4+复合掺杂的LiFePO4电极材料。采用X射线衍射、恒电流充放电和循环伏安研究复合掺杂对 LiFePO4结构和电化学性能的影响。结果表明:复合掺杂能够提高 LiFePO4的首次放电比容量,0.1C和1C的放电容量分别达到147.2mA·h/g 和133.3mA·h/g。循环伏安测试结果表明:复合掺杂改善了LiFePO4的导电性能,增强了Li+的脱嵌可逆性。 通过固相反应制备了Mg2+和Co4+复合掺杂的LiFePO4电极材料。采用X射线衍射、恒电流充放电和循环伏安研究复合掺杂对 LiFePO4结构和电化学性能的影响。结果表明:复合掺杂能够提高 LiFePO4的首次放电比容量,0.1C和1C的放电容量分别达到147.2mA·h/g 和133.3mA·h/g。循环伏安测试结果表明:复合掺杂改善了LiFePO4的导电性能,增强了Li+的脱嵌可逆性。
