Herein, a design of flexible triboelectric generator integrated with high-efficiency energy storage unit (FTEG-ES) is proposed. The power generation unit is a flexible triboelectric generator (FTEG). Natural rubber and polyethylene terephthalate (PET) release film with silicone oil on the surface are used as the friction layer, and the polyvinylidene fluoride (PVDF) layer prepared by electrospinning is added compared with traditional structure to improve output performance. The flexible solid-state capacitor made of chemical cross-linked poly(vinyl alcohol)−H2SO4 hydrogel (CPH) and activated carbon is used as an energy storage unit. The test results prove that adding the PVDF layer effectively increases the output performance of FTEG. The open-circuit voltage and short-circuit current are increased by 19% and 47%, respectively. The short-circuit current density and maximum output power are up to 1.30 μA cm−2 and 100 μW cm−2, respectively. The flexible solid-state capacitor can store energy more efficiently than electrolytic capacitors. The charging speed of the flexible solid-state capacitor is increased by 34.4% compared with electrolytic capacitors when charge the 1 mF capacitor to 1.5 V. Finally, the experiments show that FTEG-ES can be used as a backup power source for low-power devices. The feasibility of triboelectric generator applications is explored by this work.
