Hydrogel electrolytes have been widely explored in flexible zinc batteries owing to their considerable mechanical strain and water-retaining properties. However, it is difficult to balance the contradiction between the ionic conductivity and the mechanical strength due to the deterioration of structural stability with the addition of electrolyte salts. To address this, we designed a coassembling organic-inorganic hydrogel (P-P/M) based on poly(vinyl alcohol)-polyacrylamide (P-P) interpenetrating matrix decorated with Zn-based montmorillonite (Zn-MMT).
