Defect-free solvothermally assisted synthesis of microspherical mesoporous LiFePO4/C†
Abstract
Recent studies have shown that the power capability of LiFePO4 is dramatically enhanced by reducing the size of the LiFePO4 particles to nanometer dimensions. Unfortunately, the resulting intrinsically low tap density of the nano-LiFePO4 cathode significantly reduces the volumetric energy density, which is a major hurdle for the successful commercialization of this material. Here, we report the facile synthesis of carbon-coated LiFePO4 (LiFePO4/C) with a mesoporous microspherical morphology via a solvothermal process, using
