ABSTRACT Global issues such as climate change, decline of nonrenewable energy sources, and geopolitical tensions are all part of today's energy crisis, which has a direct impact on issues with energy harvesting and consumption. As a result, energy storage technologies like supercapacitors are attracting a lot of attention from academics. In this work, we synthesized 0.5, 1.0, and 1.5 atomic percentages of Mn‐doped Ba(OH) 2 using the successive ionic layer adsorption and reaction (SILAR) method on the SS substrates. In this method, film was deposited via continuous adsorption of cations and anions from their solutions for fixed SILAR cycles. Electrochemical investigation of Mn‐doped Ba(OH) 2 electrodes has been conducted via CV, GCD, and EIS techniques. 1.0 at. % Mn‐doped Ba(OH) 2 electrode displays a higher specific capacity of 562.56 C g −1 for 1 mV s −1 scan rate in 1.0 M Na 2 SO 4 electrolyte. The cyclic stability of ~91.7% for 9000 cycles has been achieved for this electrode. A symmetric device has also been fabricated using these electrodes, which are capable of storing the charge and glowing different colored LEDs, like green, red, blue, and white, for different time periods.
