💡 Novelty & Significance:
This work introduces proton-mediated coordination equilibrium as a new mechanism enabling nonfreezing Zn2+ transport in hydrogel electrolytes. By balancing phytic acid and zinc phytate, it suppresses water crystallization and sustains hopping ion transport, achieving 2.4 mS cm−1 at −60°C and stable cycling. This offers a general design principle for ultralow-temperature aqueous batteries.
