| Abstract: | Rechargeable magnesium batteries are attracting attention due to their high energy density, affordability, and the availability of magnesium. Among potential cathode materials, magnesium cobalt oxide (MgCo2O4) stands out for its promise and cost-effectiveness. This study enhances the electrochemical performance of MgCo2O4 nanoparticles by employing DC glow discharge plasma treatment. MgCo2O4 was synthesized using a hydrothermal process and then exposed to plasma, which altered the surface layers of the nanoparticles, improving properties such as wettability, adhesion, and surface area. Structural, morphological, and electrochemical studies revealed that the plasma-treated MgCo2O4 achieved a specific capacitance of 989 F/g at 0.3 mA/g and maintained a capacitive retention of around 90% over 3000 cycles, outperforming untreated MgCo2O4. These results highlight that the plasma treatment significantly enhances the electrochemical properties of MgCo2O4, making it a highly suitable material for energy storage applications in rechargeable magnesium batteries.
