Self-healing materials increase the lifetime of the supercapacitor device. The supercapacitor has a long cycle life and a quick charge–discharge rate, contributing to its high power density [ 54, 55, 56 ]. But a minor crack can reduce the supercapacitor performance, which is unsafe.
After the 10th optical, electrical and magnetic healing processes, the supercapacitor restored the areal capacitance of 710, 702, and 609 mF cm −2 at the current density of 10 mA cm −2, which was estimated to be 95.2%, 93.8%, and 86.1% in healing efficiency, respectively.
Importantly, the supercapacitor operates over a wide voltage window (0–1.2 V) and provides excellent cyclic performance with capacitance retention of 97% after 10 000 cycles and 94% after self-healing. In summary, the developed self-healable supercapacitor exhibits considerable potential as a high-performance energy storage device.

Intrinsic self-healing mechanism can do multiple healing because it uses a reversible bond formation technique and does not require any external healing agent. But, it reduces the operating temperature range of the supercapacitor because healing material will creep. Also the glass transition temperature (Tg) is low of healing materials.
