在表面修饰的介孔碳微球(MCMB)中获得了高负极性能的干式聚合物锂离子电池。将MCMB和聚氯乙烯(PVC)混合物在700℃惰性气氛下加热6h。通过这种处理，MCMB的表面覆盖了来自聚氯乙烯热解的低结晶碳材料。表面修饰的MCMB电极在干式聚合物电解液中的可逆容量为300mAHg(-1)，与液体电解液中的可逆容量相当。(C)2007 Elsevier B.V.保留所有权利。
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 degrees C for 6 h under inert atmosphere. By this treatment, the surface of MCMB is covered with low-crystallin e 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.
