Here, we synthesized a dual-function hydrogel electrolyte based on polyacrylamide and poly(ethylene dioxythiophene):polystyrene (PPP).

The developed hydrogel exhibits relatively good ionic conductivity (1.6 × 10<sup>-3</sup> S cm<sup>-1</sup>) and excellent electrochemical stability, surpassing 2.5 V on linear sweep voltammetry tests.

The rechargeable PPP hydrogel electrolyte-based hybrid aqueous battery with zinc anode achieved more than 600 cycles.
