Abstract

Nanorod-shaped LiMn _1.5Ni _0.5O ₄ cathode powders were synthesized by a co-precipitation method with oxalic acid. Their structures and electrochemical properties were characterized by SEM, XRD and galvanostatic charge-discharge tests. The resulting nanorod-shaped LiMn _1.5Ni _0.5O ₄ cathode active materials delivered a specific discharge capacity of 126 mAh g ^-1 at 0.1 C rate. These active materials exhibited better capacity retention and higher rate performance than those of LiMn _1.5Ni _0.5O ₄ cathode powders with irregular morphology.
