High-rate aqueous hybrid supercapacitors (AHSCs) have attracted relevant scientific significance owing to their expected energy density, supercapacitor-level power and battery-level density. In this work, a bimetallic nanostructured material with chromium-incorporated cobalt oxide (CCO, i.e., CoCr2O4) was prepared via hydrothermal method form stable cubic obelisk structure. Compared CCO materials using traditional methods, displayed nanowire structure (50 nm diameter), suggesting an enhanced specific surface area large number of active sites for chemical reactions. The electrode possessed high capacitance (2951 F g–1) at current density 1 A g–1, minimum Rct (0.135 Ω), the highest retention (98.7%), making it ideal AHSCs. Ex situ analysis based on X-ray diffraction (XRD) photoelectron spectroscopy (XPS) showed favorable stability after 10,000 cycles without any phase changes being detected. GGA + U methods employed in functional theory (DFT) also highlighted metallic properties originating from synergistic effect semiconducting Cr2O3 Co3O4 materials.
