It has been proved that the material structure has a great influence on its electrochemical performance. The suitable pore structure and specific surface are the premis of electrode for double-layer capacitor with excellent performance. Besides, it could be obviously improved by increasing suitable surface functional groups for the better wettability between electrode and electrolyte. Removing ash has significant contribution for improving electrochemical performance of electrode. The resistance of electric double-layer capacitor can be dropped for it high degree of graphitization which is good for improving performance of electrode. Electrode with significant amount of disordered structure and defects has high-specific surface area and well-developed pore structure. Thus, the mechanism of graphitization influence is still not clear on electrochemical performance.%电极材料结构对其电化学性能影响较大,具备合适的孔隙结构以及比表面积是双电层电容器电极电化学性能优异的前提.增加其某些表面官能团可以提升电极对电解液的浸润性,提升其的电化学性能.灰分的脱除对于改善其电化学性能具有显著作用.高石墨化程度的电极材料可以降低双电层电容器的内阻,提升双电层电容器的功率密度;无定型碳材料则具备比表面积高、 孔隙发达等优势,因此电极材料石墨化程度对其电化学性能的影响机制尚无定论.
