Summary
Multifunctional high strength and high energy epoxy composite structural supercapacitors with wet-dry operational stability†. We demonstrate the fabrication of multifunctional structural supercapacitors that maintain energy storage capability under both mechanical stresses and water immersion. This is based on the infiltration of bisphenol A ionic liquid epoxy resin electrolytes infiltrated into nanoporous silicon interfaces that play the dual role of charge storage and mechanical reinforcement of the energy storage composite material. These structural composites maintain full energy storage capability (5–8 W h kgÀ1) under tensile stresses over 1 MPa, with nearly 100% energy retention after 4000 cycles. Among the many important features for a structural supercapacitor, the choice of electrolyte is critical in dictating mechanical, ionic, and diffusion properties into the charge
