Redox‐Active Oxide/molten Salt Composites for Hybrid Thermal‐Chemical Energy Storage
Advanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.Redox‐active oxide–molten salt composites integrate sensible, latent, and thermochemical energy storage within a single particle. A porous Ca2AlMnO5+δ matrix infiltrated with eutectic NaCl/CaCl2 achieves a high‐energy density (267 kJ kg−1) over a narrow, 150 °C temperature window, offering a promising solution for high‐temperature thermal energy ...
