摘要

活性炭负极容量的有效利用率是导致双电层电化学电容器和C/Ni(OH)2非对称电化学电容器容量性质差异的主要因素,并可将其作为非对称电化学电容器容量设计和测算的依据;本文引入Ni(OH)2正极有效活性物质概念,以正极有效活性物质的量匹配负极的设计容量,从而优化正、负极的容量匹配,改善非对称电化学电容器的容量和大电流性能.

Abstract

The energy storage mechanisms of electrochemical double-layer capacitor (EDLC) and C/Ni(OH)_2 hybrid capacitor had been studied. The results proved that,the difference between the capacity of EDLC and C/Ni(OH)_2 hybrid capacitor was detemined by the effectiveness usage of the activated carbon negative electrode, which is a criterion to estimate or design the theoretic capacity of the C/Ni(OH)_2 hybrid capacitor.The electrochemical availability of activated matter in Ni(OH)_2 electrode was introduced,and the quantity of the activated matter in Ni(OH)_2 electrode should be compatible with the capacity of carbon electrode .When the capacities of Ni(OH)_2 electrode and activated carbon electrode were matched well,the capacity and high rate performance of the hybrid capacitor would be improved.
