本文综述了目前碳基纳米结构材料及其复合材料用作超级电容器电极的研究概况。特别强调了超级电容器的基本原理和影响其性能的各种因素。重点介绍了碳基材料及其复合材料的性能和稳定性。已经发现伪活性物质，例如导电聚合物/金属氧化物，表现出伪电容行为，并且碳基材料表现出双电层电容。碳基材料，例如石墨烯、碳纳米管和碳纳米纤维，为导电聚合物/金属氧化物的沉积提供了高表面积，这促进了有效的离子扩散现象，并有助于具有优异循环稳定性的碳基复合材料的更高比电容。然而，从以成本有效和简单的方式开发高能量超级电容器装置的角度来看，仍然存在进一步的研究范围。这篇评论对从事碳化学研究或对碳化学感兴趣的研究人员和新兴科学家有价值。
This critical review provides an overview of current research on carbon-based nanostructured materials and their composites for use as supercapacitor electrodes. Particular emphasis has been directed towards basic principles of supercapacitors and various factors affecting their performance. The focus of the review is the detailed discussion regarding the performance and stability of carbon-based materials and their composites. Pseudo-active species, such as, conducting polymer/metal oxide have been found to exhibit pseudo-capacitive behavior and carbon-based materials demonstrate electrical double layer capacitance. Carbon-based materials, such as, graphene, carbon nanotubes, and carbon nanofibers, provide high surface area for the deposition of conducting polymer/metal oxide that facilitates the efficient ion diffusion phenomenon and contribute towards higher specific capacitance of the carbon based composite materials with excellent cyclic stability. However, further scope of research still exists from the view point of developing high energy supercapacitor devices in a cost effective and simple way. This review will be of value to researchers and emerging scientists dealing with or interested in carbon chemistry.
