摘　　要：用正交设计法合成Li-Fe复合氧化物 ,最佳条件为 :Li/Fe =1.3,灼烧温度为 550℃ ,掺入Co ,Ni等元素对其充放电性能不利。用它为负极 ,Li1 -xCo1 -yMyO2 -δ为正极 ,以LiOH水溶液为电解质 ,组成实验室电池 ,通过充放电实验证明 ,Li-Fe复合氧化物在水溶液中性能稳定 ,有一定的比容量 ,有希望作为锂离子二次水溶液电池负极 ,但其循环性能较差。Li-Fe complex oxides were synthesized by rhombic designing.The best conditions were Li/Fe=1.3,ignition temperature 550℃,but the doping elements Co,Ni didn't help for charging/discharging.The lab's batteries were assembled with Li-Fe complex oxides anode,Li 1- x Co 1- y M y O 2-δ cathode and LiOH aqueous solution.Charged and discharged,the results showed that the complex oxides could be used as anode for aqueous solution Li-ion secondary batteries,but it had poor cycle life.
