A novel anodic nanostructured stainless steel-304L oxide as an emerging electrode material for high energy density asymmetric supercapacitors: experimental and DFT insights.

ABSTRACT: The electrode material plays a significant role in the performance of supercapacitors. Therefore, the development of a novel electrode material for high energy density, high power density, and stable supercapacitors is highly desirable. The emergence of the stainless steel 304L (SUS-304L) oxide nanostructure as an electrode material provides an opportunity to explore its supercapacitive behavior. In the present study, a simple and facile technique of anodization was employed to synthesize nanostructured SUS-304L oxide (in powder form), which would be otherwise impossible to achieve using the existing synthetic routes. The structural and microscopic results confirm the formation of multiple phases (Fe₂O₃, Fe₃O₄, and NiCr₂O₄),
