| Abstract: | Petroleum Pitch Based Mesocarbon Microbeads (P-MCMB) were heated under different maximum heat treatment temperatures (HTT max ). The microstructures of these samples were analyzed by means of XRD techique. The charging-discharging performances of these samples were investigated by the galvanostatic charging-discharging experiments and the powder microelectrode cyclic voltametry experiments. The correlations between their electrochemical performances and the microstructures were discussed. |
