A kind of artificial graphite particles, so called as mesocarbon microbeads (MCMB) particles was treated in Ar-H2 plasma atmosphere to create the functional surface, and to improve electrochemical properties of graphite particles. The electrochemical properties of plasma-treated MCMB particles and the influence of post-processing atmosphere on electrochemical properties were investigated as anode of lithium-ion rechargeable battery. The modification of surface morphology and structure by H2 plasma treatment, and the protection of adsorbing species on the surface by controlling post-processing atmosphere of dry Ar lead to the improvement of the first charge/discharge efficiency and the reversible capacity.
