Summary: Flexible zinc-air batteries with gel polymer electrolyte (GPE) are considered promising for next-generation wearable devices due to their high energy density, low cost, safety, and environmental friendliness. However, the evaporation of liquid component in GPE significantly reduces battery performance and lifespan. To address this issue, a hierarchically porous PVA/PAA hybrid GPE is developed, which improves electrolyte uptake and retention properties, and enhances ionic conductivity. The hybrid GPE demonstrated excellent cycling stability, rate characteristics, and power output in zinc-air batteries, showing their feasibility for powering wearable smart watches.
