Self-charging supercapacitor power cell (SCSPC) is one of the nascent areas of research for the surrogating to renewable energy resources. The prime obstacle in development SCSPC is the utilization of liquid electrolyte hinders the energy conversion efficiency which in turn creates a demand to explore and replace with new solid electrolytes for the SCSPCs. Herein, a new all solid state self-charging supercapacitor power cell (SCSPC) has been fabricated using Nafion as solid polyelectrolyte cum energy harvester and spray coated MoS2 quantum sheets (MoS2-QSs) as energy storage electrodes. The Nafion polyelectrolyte exhibits energy harvesting characteristics under mechanical deformation due to the change in ion concentration gradients between electrodes that leads to the generation of output voltage. The fabricated MoS2-Nafion-MoS2 SCSPC shows the self-charging characteristics upon various levels of compressive forces with a self-charging voltage of 243 mV. The self-charging mechanism of the fabricated MoS2-Nafion-MoS2 SCSPC is explained via piezo-ionic effect. These experimental findings have profound significance in the context of developing a potential all-in-one self-charging system.
