💡 Novelty & Significance:
The novelty lies in a cationic PAM-N⁺/HSiO₂ hydrogel that decouples ionic conductivity, Zn²⁺ transference, and mechanical strength via electrostatic anion anchoring and HSiO₂ crosslinking. It achieves 0.75 transference, 27.06 mS cm⁻¹, and ultralong cycling (5182 h), plus flame retardancy and biodegradability—advancing eco-friendly, high-performance quasi-solid-state zinc-ion batteries.
