Abstract High‐entropy alloys (HEAs), containing five or more elements in equal proportions, have recently made significant achievements materials science due to their remarkable properties, including high toughness, excellent catalytic, thermal, and electrical conductivity, resistance wear corrosion. This study focuses on a HEA composed of 23Fe−21Cr−18Ni−20Ti−18Mn, synthesized via ball milling. The alloy was treated with hydrochloric acid (HCl) enhance its active surface area. untreated the HCl‐treated (HEA‐T) were then evaluated as potential cathode for supercapacitors (SCs). X‐ray diffraction (XRD) energy‐dispersive spectroscopy (EDX) confirmed that HEA's composition crystalline structure remained stable during treatment, no new phases forming. treatment significantly increased area by ~20 times, pore volume ~10 improved microstructural homogeneity. HEA‐T electrode demonstrated superior specific capacitance, lower internal resistance, better cycling stability than electrode. At 0.5 A/g current density, capacitance (Csp) 600 F/g, approximately two times higher HEA. enhanced performance suggests could lead development high‐performance SCs.
