Porous Polyacrylamide Electrolytes with Improved Ionic Conductivity for Long-Cycle-Life and High-Power-Density Flexible Zinc–Air Batteries
Polyacrylamide (PAM) hydrogels are simple to prepare under readily controllable conditions, making them suitable for the large-scale production of high-quality electrolytes. However, when used in zinc–air batteries, continuous water evaporation through the semi-open battery structure causes electrolyte desiccation, r...
