Stabilizing Water Molecules in Hydrogel Electrolytes Enables 2.8 V‐Class Purely Aqueous Zn–Li Hybrid Batteries

ABSTRACT Currently, reported high‐voltage aqueous zinc batteries generally operate below 2.0 V. Achieving a discharge plateau/average operating voltage exceeding 2.0 V typically requires charging voltages above 2.5 V; however, the limited electrochemical stability of water molecu...
