英文摘要	Nanomicro spheres of LiNi0.5Mn1.5O4 materials are prepared by carbonate coprecipitation method. The effect of calcination temperatures on morphology and electrochemical property is explored. Results show that the structure of the material becomes more compact with the increase of the temperature, which is propitious to the improvement of electrical conductivity and activation level of the material. The charge-discharge tests show that the sample obtained at 850 °C (LNMO850) exhibits optimal rate capability and cyclic stability, due to the fact that LNMO850 has a high diffusion coefficient, which is propitious to the improvement of electrical conductivity and activation level of the material. © 2018 American Society of Mechanical Engineers (ASME).
