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.
