Solid-State Supercapacitors with Enhanced Performance Using Al³⁺-Doped Li⁺ Ion Perovskite Electrolyte Integrated with Carbon Aerogel Electrode.

ABSTRACT: We report the performance of solid-state ceramic supercapacitors (SSCs) based on a novel composite electrolyte comprising aluminum-doped lithium lanthanum titanate perovskite, Li_0.36La_0.56Ti_0.995Al_0.005O₃ (Al³⁺-doped LLTO), and the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF₄). Rietveld refinement of X-ray diffraction data confirms the preservation of the tetragonal perovskite phase after Al³⁺ substitution, indicating structural stability of the host lattice. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy further corroborate the successful incorporation of Al³⁺ without forming secondary phases. The addition of ∼6 wt % EMIM BF₄ into Al-LLTO mat
