Abstract

The spinel LiNi_0.5Mn_1.5O₄ powders with high crystallinity and well-developed octahedral morphology were synthesized by a ultrasonic spray pyrolysis method using citric acid as a polymeric agents. The LiNi_0.5Mn_1.5O₄ powders were characterized by X-ray diffraction, scanning electron microscopy, and electrochemical testing. The LiNi_0.5Mn_1.5O₄ material delivers a discharge capacity of more than 138 mAh g^-1 with excellent capacity retention of more than 97% after 50 cycles even at 55°C.
