Mesoporous La 2 CrMnO 6 double perovskite is successfully synthesized using the hydrothermal technique, and characterized its physicochemical properties using X‐ray diffraction, X‐ray photoelectron spectroscopy, Brunauer–Emmett–Teller surface area analysis, scanning electron microscopy, and transmission electron microscopy. The synthesized material exhibits a high surface area of 57.07 m 2 g −1 , providing more active sites for electrochemical charge storage. The electrochemical performance of the La 2 CrMnO 6 as an electrode material is evaluated for the first time, which reveals an excellent specific capacitance of 1416 F g −1 at 1 A g −1 in a three‐electrode setup. Results suggest that mesoporous La 2 CrMnO 6 double perovskite is a promising electrode material for electrochemical energy storage applications.
