Robust Polymer Hydrogels Improve Electric‐Fish‐Inspired Batteries

Advanced Functional Materials, EarlyView.
ABSTRACT Electric‐fish‐inspired hydrogel batteries based on ion‐concentration gradients offer an attractive route to soft power sources; however, the poor mechanical properties of existing hydrogels limit device assembly and performance. Here, we report poly(ethylene glycol) methyl ether acrylate hydrogels that enable ion‐gradient batteries composed of
