In this paper, we propose the design of a family hydrogel electrolytes that featuring freezing resistance, flexibility, safety, superior ionic conductivity and long-term stability to realize anti-freezing flexible aqueous batteries.
Abstract Prussian blue analogue (PBA)‐type metal hexacyanoferrates are considered as significant cathodes for zinc batteries (ZBs). However, these PBA‐type cathodes, such cyanogroup iron hexacyanoferrate (FeHCF), suffer from ephemeral lifespan (≤1000 cycles), and inferior rate capability (1 A g −1 ). This is because the redox active sites of multivalent (Fe(III/II)) can only be very limited activated thus utilized. attributed to spatial resistance caused by compact cooperation interaction...
Abstract Stretchable devices need elastic hydrogel electrolyte as an essential component, while most hydrogels will lose their stretchability after being incorporated with strong alkaline solution. This is why highly stretchable zinc–air batteries have never been reported so far. Herein, super‐stretchable, flat‐ (800% stretchable) and fiber‐shaped (500% are first developed by designing alkaline‐tolerant dual‐network electrolyte. In the electrolyte, sodium polyacrylate (PANa) chains...
