   超级电容器技术的发展核心是电极材料。目前主要集中在对碳基材料、稀有金属氧化物和导电聚合物等的研究。美、日等利用煤、石油焦、中间相炭微粒为原料,制备出高比表面活性炭并进行了工业化生产。我国学者在20世纪90年代展开了类似的研究工作并取得了一定的进展。虽然制备高比表面活性炭仍以KOH或NaOH为主,但所涉及的富碳材料很多,有石油焦、沥青、木质素、木粉、椰壳、棕榈壳、核桃壳、稻壳、葵花籽壳、玉米芯等,以及化工原料聚丙烯腈碳纤维、酚醛树脂等。我国椰壳活性炭高比表面积活性炭产业的更大障碍是生产成本过高,所以,优化高比表面积活性炭的生产工艺、降低其生产成本将成为该方面科研工作者研究的重点。

   竹材作为一种可再生的生物质原料,具有生长快、更新迅速、再生能力强、一次造林成功即可持续经营利用等特点。而且我国竹类资源丰富,分布广泛,为我们提供了原材料上的便利。竹材具有特殊的孔隙构造,经过高温热处理形成的竹炭继承了其原有的大孔隙结构特征,孔径主要分布在0.55至5.50微米之间。而竹炭经过活化处理后,孔隙结构更为发达,具有丰富的孔隙分布特征和高比表面积。故选择椰壳活性炭彩经网竹材为原料通过热解炭化、活化以制备适合超级电容器用竹基高比表面积活性炭。为了尽量地减少生产成本,有必要对竹材的炭化温度进行研究,探讨出较佳的炭化温度。
