层次孔炭材料呈合理的微孔-中孔/大孔结构及孔径分布,具有高的电化学活性表面、极短的扩散距离和较高的传质速率,在用作储能器件电极材料时,表现出优异的功率特性。通过综述近来年层次孔炭材料的设计制备及其在储能领域的应用进展,重点介绍了本课题组自2008年以来的研究成果,进而展望了层次孔炭材料的发展方向。指出:层次孔炭材料主要通过模板法或模板-活化联合法制备。这两种方法可以实现炭材料纳米结构的精确调控。最近,开发出来的更简易的免模板法展现出较好的应用前景。
Hierarchy of porous carbon material has a reasonable micropore - mesopore / macroporous structure and pore size distribution, has a high electrochemical active surface, a very short diffusion distance and high mass transfer rate, when used as an energy storage device electrode material , Showing excellent power characteristics. Through reviewing the design and preparation of pore carbon materials in recent years and its application in energy storage, the research results of our group since 2008 are mainly introduced, and then the development direction of hierarchical pore carbon materials is prospected. It is pointed out that the hierarchical pore carbon material is mainly prepared by the template method or the template-activation combination method. These two methods can achieve precise control of carbon nanostructures. Recently, the more simple template-free method developed has shown a good application prospect.
