Fabrication of microspherical LiMnPO4 cathode material by a facile one-step solvothermal process

The microspherical LiMnPO4 cathode material was successfully prepared for the first time by a simple one-step solvothermal process in the presence of critic acid. The reaction conditions (reactant concentration, reaction temperature) were used further to fabricate the size, surface coarseness and morphology of the microspherical LiMnPO4. The as-prepared microspherical LiMnPO4 at variant conditions exhibited remarkably different discharge capacity and rate capacity, indicating the potential of the suggested method in tuning the morphology and the structure of LiMnPO4 to improve its electrochemical performance.
