摘要: 本文以水合氢氧化锂 (LiOH .H2 O)、水合硝酸锰 (Mn(No3) 2 .6H2 O) ,水合氯化锂 (LiCl.H2 O)为原料 ,用类溶胶 凝胶法制备了LiMn2 O4 δClδ,并且以此作正极进行了电化学测试 .结果表明 ,掺氯的尖晶石LiMn2 O4 正极材料具有优异的稳定性 ,且循环稳定后 ,容量几乎没有衰减 .

关键词: 类溶胶凝胶法, LiMn2O4δClδ, 正极材料

Abstract: LiMn 2O 4 δ Cl δ was synthesized by like sol gel methode, with calculated LiOH.H 2O, Mn(No 3) 2.6H 2O and LiCl.H 2O, and made electrochemical test with these compounds as positive materials. Result demostrated that LiMn 2O 4 δ Cl δ cathode material has exellent stability and nearly no capacity loss after reaching stability.

Key words: Like sol gel methode, LiMn 2O 4 δ Cl δ, Cathode material
