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.

Hierarchical porous carbons (HPCs) possess a multimodal pore size distribution of micro-, meso-, and/or macropores, and thus show high electrochemically accessible surface area, short diffusion distance, and high mass transfer rate when used as electrode materials in energy storage devices. Because of this, HPCs show excellent rate capabilities and have attracted considerable attention in recent years. Normally, HPCs are prepared by templating methods or combined templating/activation methods, in which carbons are inverse replicas of the template and the pore structure parameters of HPCs can be easily tuned. Recently, simpler template-free methods have been developed and show a promising future. In this review, we describe the recent advances in design, preparation, and electrochemical performance of HPCs, with particular attention to the main achievements using HPCs developed in our groups since 2008. Finally we give a brief outlook.
