High tap-density Li0.99W0.01FePO4/C composite have been synthesized via a simple and low-cost solid state-carbothermal reduction method, using Fe2O3 and citrate ferric as the Fe3+ precursors and citric radical containing in citrate ferric as both carbon source and reducing agent. The structure, morphology, and physicochemical properties of Li0.99W0.01FePO4/C composite were characterized by XRD, SEM, laser diffraction and scattering measurement, and tap-density testing. It is observed the particle distribution of the Li0.99W0.01FePO4/C composite is bimodal distribution. Because of the smaller p...
