层次多孔碳的制备及其电化学性能的研究

Preparation of Layered Porous Carbon and Its Electrochemical Properties

以间苯二酚-甲醛(RF)作为碳源,利用具有中空结构的聚苯乙烯球(PS)作为模板,在高温下碳化得到三维层次多孔碳。采用扫描电镜、循环伏安及恒流充放电等方法对其性能进行测试。结果表明,层次多孔碳在高倍率条件下具有优异的电化学性能。

Taking resorcinol and formaldehyde as a carbon source,and a polystyrene sphere(PS)having a hollow structure was used as a template to carbonize at a high temperature to obtain a three-dimensional porous carbon.The performance was tested by scanning electron microscopy,cyclic voltammetry and constant current charge-discharge.The results showed that the layered porous carbon has excellent electrochemical performance under high rate conditions.
