High energy density solid state symmetric supercapacitors using ionic liquid dispersed Li⁺ ion-perovskites.

ABSTRACT: The study reports solid-state ceramic supercapacitors (SSCs) assembled using a novel composite electrolyte based on Li⁺ ion conducting perovskite-type LLTO (Li_0.34La_0.51TiO₃) and an ionic liquid (EMIM BF₄). Small amounts of various ionic liquids (ILs) were added to LLTO to enhance the ionic conductivity and improve electrode compatibility. The optimal composition with approximately ∼6 wt% EMIM BF₄ in LLTO exhibited a high ionic conductivity of around ∼10^-3 Ω^-1 cm^-1 at room temperature, nearly three orders of magnitude higher than that of the pristine LLTO. Optimized electrolyte composition was therefore used for fabrication by compressing between high surface area activated carbon-coated copp
