Chaotropic Urea-Regulated PAM-Agar Hydrogel Electrolytes for Flexible Zn-Air Batteries
Hydrogel electrolytes are central to flexible Zn-air batteries (FZABs) because they determine the ion transport and interface chemistry of the cathode and anode. However, the dense hydrogel networks restrict ion migration and lead to an increased level of polarization during battery operation. Herein, a facile additi...
