Title:
STRETCHABLE, COMPRESSIBLE AND ANTI-FREEZING ORGANIC HYDROGEL ELECTROLYTE-BASED SUPERCAPACITOR AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/019675
Kind Code:
A1
Abstract:
The present invention belongs to the field of supercapacitors, and in particular, to a stretchable, compressible, anti-freezing organic hydrogel electrolyte-based supercapacitor and a preparation method therefor. The organic hydrogel electrolyte, a monomer of which is acrylamide and methacryloylethyl sulfobetaine, is doped with soy protein in a polymer network. The organic hydrogel electrolyte has excellent tensile and compression performances. When the organic hydrogel electrolyte is stretched to 600% strain or compressed to 80% strain, the organic hydrogel electrolyte can still be restored to the original state. The room-temperature conductivity can reach 37.5 mS·cm-1, and has good electrical performance. The supercapacitor prepared from the organic hydrogel electrolyte has good double-layer behavior, reversibility, excellent rate performance, and mechanical and anti-freezing properties, and can be applied to the field of supercapacitors with higher requirements for mechanical and anti-freezing properties.
