Synthesis of Monodiperse Carbon-Coated Lithium Iron Phosphate
Carbon-coated lithium iron phosphate (LiFePO4/C) powders were synthesized by a simple hydrothermal method and incipient wetness impregnation. The structural and morphological properties were investigated by XRD and SEM. The results show that the LiFePO4 powders are composed of small plate particles with diameter size of 1-3μm and thickness of 0.2μm. Through incipient wetness impregnation, monodisperse LiFePO4/C particles were obtained and carbon was uniformly distributed over LiFePO4 particles to avoid the direct contact of them, which reduces the trend of agglomeration of the particles during the calcinations process.
