摘　　要：寻求兼具高能量密度和高功率密度的储能器件是电化学储能领域一直以来的发展目标,也是应对全球能源危机发展可再生能源的有效举措.胶体离子超容电池体系基于电极材料水平上的创新,将电池的高能量密度和超级电容器的高功率密度及长循环寿命集结于一体,是极具发展前景的一种新型储能体系.胶体离子超容电池体系的优异电化学性能源于其活性物质的多尺度与反应特性,这要求从微观上的化学尺度到宏观上的器件系统尺度对整个电化学单元实现多尺度调控以及复杂的原位耦合反应设计.在前期工作的基础上,从尺度和反应两个重要方面重新审视胶体离子超容电池体系产生优异电化学性能的本质.The search of energy storage devices with high energy density and high power density is an ultimate goal of development in the electrochemical energy storage field and an effective measurement for the development of renewable energy in response to the global energy crisis.Based on the innovation of the electrode material,colloidal supercapattery combined the merits of battery(high energy density)and supercapacitor(high power density and long cycling life)to actualize both high energy density and high power density.The excellent electrochemical performance of the colloidal supercapattery system is closely related to the multi-scale existing form of the active material,which requires the multi-scale control from the microcosmic chemical scale to the macroscopic device system scale and in situ formation mechanism including complex interaction of the whole electrochemical unit.On the basis of the previous work,the reasons for the excellent electrochemical performance of the colloidal supercapattery system are reviewed from scale and reaction regime.
