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 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.

在表面改性的中间相碳微球（MCMB）中，干聚合物锂离子电池获得了高阳极性能。在惰性气氛下，将MCMB和聚氯乙烯（PVC）的混合物在700℃加热6小时。通过这种处理，MCMB的表面覆盖了由PVC热解产生的低结晶碳材料。应用于干聚合物电解质的表面改性MCMB电极显示出300 mAh g⁻¹的可逆容量，这与在液态电解质系统中获得的容量相当。（C）2007爱思唯尔有限公司。保留所有权利。
