abstract:
In this article, a flexible self-healing supercapacitor was fabricated by assembling two activated carbon cloth (ACC)/Mn2O3 electrodes and a self-healing physically cross-linked PVA-H2SO4 gel electrolyte. The results show that ACC/Mn2O3 exhibited excellent electrochemical performance (the area specific capacitance at 1 mA/cm2 was 2 264 mF/cm2, and the capacitance retention rate after 10 000 cycles was 93%). The supercapacitors showed excellent flexibility and good self-healing ability, and the capacitance retention rate after 4 cut-healing cycles was about 80.47%.
