Surface-modified meso-carbon microbeads anode for dry polymer lithium-ion batteries

A high-anode performance for dry polymer lithium-ion batteries was obtained in the surface-modified meso-carbon microbeads (MCMB). MCMB and polyvinylchloride (PVC) mixture was heated at 700 °C for 6 h under inert atmosphere. By this treatment, the surface of MCMB is covered with low-crystalline carbon material derived from PVC pyrolysis. The surface-modified MCMB electrode applied to dry polymer electrolytes shows a reversible capacity of 300 mAh g−1, which is comparable to those obtained in the liquid electrolyte systems.
