Herein, we present a one-body strategy that utilizes hydrogel as ionic conductive medium both flexible aqueous zinc-ion batteries strain sensors. poly(vinyl alcohol) network incorporates nano-SiO2 cellulose nanofibers (referred to PSC) in ethylene glycol/water mixed solvent, balancing mechanical properties (tensile strength 6 MPa) diffusivity at −20 °C (2 orders magnitude higher than 2 M ZnCl2 electrolyte). Meanwhile, cathode lattice breathing during solvated Zn2+ intercalation dendritic Zn protrusion anode interface are mitigated. Besides robust cyclability Zn∥PSC∥V2O5 prototype within wide temperature range (from 80 °C), this microdevice seamlessly integrates with sensor, enabling precise monitoring muscle response dynamic body movement.

Abstract The reversibility and sustainability of Zn anode are greatly hampered by the dendrite growth side reactions. Orientational deposition, which allows assembly deposits in a highly ordered compact manner, offers solution to these issues enabling dendrite‐free anodes.
