Abstract
Atmospheric-pressure plasma jet (APPJ) treatment enhances the surface reactivity of the Zn[sbnd]Co metal layer for asymmetric supercapacitors. The device is constructed using screen-printed reduced graphene oxide (rGO) on carbon cloth as the negative electrode and electrodeposited Zn[sbnd]Co on stainless steel fiber paper (SSP) as the positive electrode. After 180 s of APPJ treatment, the device exhibited notable improvements in energy storage performance, including efficient material utilization, reduced charge-transfer resistance, and excellent capacitance retention. Moreover, APPJ treatment effectively enhanced capacitance retention under flexing. These results demonstrate that APPJ is an effective strategy to modify electrode surfaces and boost the electrochemical and mechanical performance of flexible supercapacitors.
