An Intrinsically Stretchable and Compressible Supercapacitor Containing a Polyacrylamide Hydrogel Electrolyte, Angewandte Chemie International Edition (2017). DOI: 10.1002/anie.201705212

A polyacrylamide hydrogel electrolyte renders supercapacitors extraordinarily stretchable and compressible. Flexible, wearable electronics require equally flexible, wearable power sources. Chinese scientists have introduced an extraordinarily stretchable and compressible polyelectrolyte which, in combination with carbon nanotube composite paper electrodes, forms a supercapacitor that can be stretched to 1000% in length and compressed to 50% in thickness with even gaining, not losing capacity.

Supercapacitors bridge the gap between batteries, which are merely energy-storing devices, and normal capacitors, w...
