Electronic textiles (e-textiles), having the capability of interacting with human body and surroundings, are changing our everyday life in fundamental meaningful ways. Yet, expansion field e-textiles is still limited by lack stable biocompatible power sources aesthetic designs. Here, we report a rechargeable solid-state Zn/MnO2 fiber battery cyclic performance exceeding 500 hours while maintaining 98.0% capacity after more than 1000 charging/recharging cycles. The mechanism high electrical mechanical due to graphene oxide–embedded polyvinyl alcohol hydrogel electrolytes was rationalized Monte Carlo simulation finite element analysis. With collection key features including thin, light weight, economic, as well energy density, could seamlessly be integrated into multifunctional on-body e-textile, which provides unit for continuous simultaneous heart rate, temperature, humidity, altitude monitoring.
