Engineering the membrane\/electrode interface to improve the performance of solid-state supercapacitors

Abstract:

This paper investigates the effect of adding a 450 nm layer based on porous TiO2 at the interface between a 4.5 μm carbon/TiO2 nanoparticle-based electrode and a polymer electrolyte membrane as a route to improve energy storage performance in solid-state supercapacitors. Electrochemical characterisation showed that adding the interface layer reduced charge transfer resistance, promoted more efficient ion transfer across the interface and significantly improved charge/discharge dynamics in a s...
