Figure 6. Self-healing performance of the supercapacitor comprising the VSNPs-PAA polyelectrolyte.

Figure 6

(a) CV curves at a scan rate of 5 mV s−1. (b) GCD curves at a charging/discharging current of 1 mA. (c) Healing efficiency calculated from CV (circle, red) and GCD (star, blue) curves. (d) A photo of three supercapacitors connected in series, one of which has self-healed twice to power an LED bulb after self-healing. (Insets show enlarged profiles of the twice self-healed supercapacitor and the lit LED bulb.)
