Abstract
The morphology of particles was a really vital parameter influencing the electrochemical properties of LiMnPO4 based cathode materials. In this work, nano-sized LiMnPO4 with various kinds of morphology were prepared by solvothermal method. Then the phase structure, micro morphology and electrochemical properties were deeply analyzed by using XRD, SEM, electrochemical workstation and battery test system. The results indicated that obtained samples with porous and spindle-shaped powders show the best electrochemical properties, contributing to the decrease of Li+ diffusion coefficient and enhancement of wetting properties between the active powders and the electrolyte.
