Abstract The development of sustainable, high‐performance electrode materials is essential for the future energy storage technologies such as supercapacitors (SCs) and batteries. 1D nanoribbons with unique fascinating properties are expected to revolutionize technologies. Herein, chemically tuned CuCo 2 O 4 (CNRs) outperform their counterparts (Co 3 Cu O) in SCs due high surface area, providing multiple active sites ion adsorption redox reactions. used nickel foam ensures a reliable electrical connection CNRs provides 3D‐conductive channels rapid transport synergistic effects. optimized CNR exhibits an impressive capacitance 1 126 F g −1 at mA cm −2 , retaining ≈93.51% its after 50 000 cycles. asymmetric coin cell SC device (CNRs//activated carbon (AC)) reveals exceptional density (ED) power (PD) values 32.2 W h kg 517 respectively. Furthermore, functional theory (DFT) based on first‐principle evaluations clarifies that diverse unbroken enhanced metallic nature. These results establish highly promising candidates next‐generation sustainable devices.
