Figure 8

(a) Plot of log (current density) versus log (scan rate) of Co, Ni and CoNi electrodes, (b) the contribution ratio of capacitive and diffusion-controlled currents of Co electrode, (c) the contribution ratio of capacitive and diffusion-controlled currents of Ni sample, (d) the contribution ratio of capacitive and diffusion-controlled currents of CoNi sample. (e) Cyclic stability plot of CoNi after 5000 charge/discharge cycle.
