| Abstract | Carbon-coated composite cathode materials are first reported in this work, prepared by the mechanochemical process with a complex metal oxide as the precursor and sucrose as the carbon source. X-ray diffraction pattern of the composite material indicates that both olivine and monoclinic co-exist. We further investigated the electrochemical properties of our composite cathode materials using galvanostatic charging/discharging tests, where our composite electrode materials exhibit the charge/discharge efficiency of 91.9%, while and exhibit the efficiency of 87.7 and 86.7% in the first cycle. The composites display unique electrochemical performances in terms of overvoltage and cycle stability, displaying a reduced gap of 141.6 mV between charge and discharge voltage and 95.0% capacity efficiency after cycles. |
