【 摘 要 】

Spinel LiMn1.5Ni0.5O4 cathode powders with different morphologies were synthesized by a co-precipitation method using oxalic acid. The calcination temperature affected the morphologies, crystalline structure and electrochemical properties of the LiMn1.5Ni0.5O4 powders. The LiMn1.5Ni0.5O4 powders obtained at a calcination temperature of 850 oC exhibited the highest initial discharge capacity with good capacity retention and high rate capability.
