Dual-Curing Composition for Gel Polymer Electrolytes and Gel Polymer Electrolytes

Highly Adhesive Gel Electrolyte Combining UV/Thermal Dual-Curing Matrix and Ionic Liquid Complexes

This technology utilizes a dual-curing polymer matrix composed of a blend of UV-curable acrylic and thermally curable epoxy polymers to simultaneously optimize the flexibility, ionic conductivity, mechanical stability, and substrate adhesion of polymer electrolytes.

Conventional gel polymer electrolytes have suffered from poor mechanical and environmental stability. Furthermore, adopting polymers with high adhesion often leads to a trade-off where increased rigidity results in reduced ionic conductivity.

This technology involves a dual-curing process using a composition of 25–35 wt% matrix-forming material (containing UV-curable compounds like PEGDA and thermally curable compounds like DGEBA in a 1:1 to 2:1 weight ratio) and 65–75 wt% ionic complex (consisting of alkali salts, plasticizers, and ionic liquids). It is ideal for electrochemical devices requiring strong substrate adhesion, such as flexible batteries, wearable pouch cells, and electrochromic devices, ensuring stable ion transport paths without delamination even under repeated bending.
