摘要(Abstract):

LiMn_(1-x)Fe_xPO_4具有成本低廉、环境友好、能量密度高和稳定性高等优点,在锂离子电池中具有良好的应用前景。目前在制备LiMn_(1-x)Fe_xPO_4的各种方法中,液相法制得的产品性能较佳。文中以葡萄糖为碳源,通过氢氧化物共沉淀法和球磨法,利用固相反应制备了碳包覆的LiMn_(0.6)Fe_(0.4)PO_4纳米颗粒。经过电化学测试,LiMn_(0.6)Fe_(0.4)PO_4在0.3 C、0.5 C、1 C和2 C倍率下的放电比容量约为127 mAh/g、119 mAh/g、104 mAh/g和82 mAh/g,且在1 C和2 C下循环200圈后的容量保持率均接近100%,该材料具有良好的倍率性能和循环稳定性。
