Abstract
Spinel LiMn1.5Ni0.5O4 materials with different morphologies were prepared by solid-state reaction method using nano-sized Mn-Ni-O precursor powders. The effect of annealing temperature on the physical properties and electrochemical performance of the LiMn1.5Ni0.5O4 cathode materials was investigated. As the annealing temperature was increased from 700 to 1000 degrees C, the particle size distinctly increased. The nano-sized LiMn1.5Ni0.5O4 powder obtained at 800 degrees C exhibited a high initial discharge capacity of 130 mA h g(-1) and good rate capability. The LiMn1.5Ni0.5O4 material annealed at higher temperature (1000 degrees C) exhibited good cycling stability.
