On the route to sustainable technology and chemistries for bio-compatible energy storage devices, water-based formulations represent a promising alternative to the solvent now in use. Several polymer-based options, including poly(2-hydroxyethyl methacrylate) (poly[HEMA]) and silicon hydrogels show excellent biocompatibility, good mechanical properties and durability.
Alongside, in supercapacitors and batteries, carbon nanotubes (CNTs) and carbon nanostructures (CNSs) are a versatile alternative to the consolidated graphitic electrode. CNTs are well-known to provide excellent mechanical properties together with electrical conductivity and large surface area.
In this work, we introduce a novel concept for integrating freestanding CNTs-based energy storage system within hydrogels, preventing direct exchange with the environment. A systematic approach in regards with the electrochemical performances (CV, GCD, EIS) and the mechanical properties identifies favourable geometries for full systems, among several solutions.
