双电层电容器储能机理研究概述

A review on the mechanism of the energy storage about the electrochemical double-layer capacitors

本文综述了双电层电容器的储能机理研究进展,详细论述了多孔碳孔结构与电解液离子之间的相互作用,介绍了多孔碳界面双电层理论,包括最早的平行板双电层模型、考虑孔隙曲率的EDCC和EWCC模型及最新发现的充电机理。经过上述讨论,认为合成具有最优微孔尺寸、合适介孔比例和结构规整的多孔碳,是今后得到高功率密度、高能量密度多孔碳基超级电容器的最佳途径。

This dissertation summarized research on the energy storage mechanism and discussed the interaction between the porous structure and the electrolyte ions.What＇s more,this review described simply the theoretical models of double electric layer including the previous parallel-plate model,the later EDCC and EWCC models taken into account curvature,and the newest charging mechanisms of EDLCs.Finally,this review concluded that the best approach to achieve high power density and high energy density for porous carbon based supercapacitors will be to synthetize the porous carbon which owns the optimal micropores size and appropriate proportional of mesopores.
