以ZnCl2和FeCl3.6H2O为原料,通过溶剂热法制备了尖晶石型ZnFe2O4材料,通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅立叶红外光谱(FT-IR)和恒流充放电测试技术对材料的结构、形貌及电化学性能进行了表征.结果表明,合成的材料为纳微多孔结构,其颗粒粒径约为250 nm,以50 mA/g的电流密度充放电时,可逆比容量为933.1 mAh/g,经过100次循环后,比容量为813.5 mAh/g,比容量保持率高达87.2％,表现出优异的循环稳定性能.当电流密度增大到400 mA/g时,其比容量约为355 mAh/g,表现出较高的倍率性能.采用该法制备得到的纳米ZnFe2O4具有比容量高、循环稳定好等优点,是一种具有较强应用前景的锂离子电池负极材料.
