Developing effective, cost‐efficient, and eco‐friendly energy storage solutions is crucial for sustainable building structures. Red mud, a waste material, was used as the electrolyte and separator in supercapacitors, alongside activated carbon derived from jute sticks coated on steel mesh electrodes. Tests on RM‐enhanced supercapacitors showed that 20% by weight of RM was the best amount. This increased the modulus of elasticity by 33%, the tensile strength by 3%, and the compressive strength by 10%. Durability was largely unaffected, with minimal additional water absorption and slight shrinkage variation. The supercapacitor cell had an extended cell potential of 1.5 V and a maximum specific capacitance of 62.3 F g‐1 at 0.4 A g‐1, as shown by electrochemical tests. This improved energy density to 19.5 Wh kg‐1, with a power density of 301.8 W kg‐1 at 0.4 A g‐1 and a maximum power density of 605.8 W kg‐1 at 0.8 A g‐1. The cell retained 77% of its initial capacitance after 450 continuous GCD cycles, demonstrating notable stability. This stability is due to the solid electrolyte and the synergy between JC and RM, indicating promising advancements for future energy storage devices.
