The results showed that the electrode reaction on cathode was controlled by the diffusion of Zn 2+ at the beginning of the discharge process. With the increase of Zn 2+ amount intercalated into the cathode, the reaction became a kinetic controlled process, i.e.a process controlled by intercalation of Zn 2+ in V 2O 5.展开更多
