Abstract:Emerging portable energy systems with integrated sustainability and improved safety have garnered growing interest in wearable electronics. Herein, a self-charging zinc-ion battery is successfully developed by integrating a PVDF−ZnO piezoelectric separator immersed in a quasi-solid-state hydrogel electrolyte (prepared using a 3 m Zn(CF 3 SO 3 ) 2 ) solution that is sandwiched between a FeVO 4 cathode and a zinc anode. This battery effectively captures energy through controlled tapping, eliminating the need for… Show more
