This work highlights the significant potential of Manganese-doped Zinc Oxide (Mn-doped ZnO) nanoparticles in enhancing supercapacitor electrodes, sparking extensive research interest. The hydrothermal synthesis method has gained prominence for fabricating Mn-doped ZnO nanoparticles. While the impact of Mn doping on other nanomaterials has been well-studied, the remains a gap in comprehensive research focused on Mn-doped ZnO nanoparticles for supercapacitors. This review addresses this gap by compiling and comparing existing research on the applications of Mn-doped ZnO in supercapacitors. Through a detailed analysis of past studies, this paper explains the distinct advantages of Mn-doped ZnO in supercapacitor applications and identifies areas for further improvement. It offers a thorough summary of the physical and electrochemical characteristics critical to supercapacitor performance, such as cyclic voltammetry, constant current charge-discharge, structure, morphology, and elemental analysis. Additionally, the review provides an in-depth discussion on how Mn doping specifically influences these performance aspects, making a significant contribution to advancing the understanding and development of superior supercapacitor technologies.
