MgxCo1-x(OH)2@C as electrode for supercapacitor: Effect of doping level on energy storage capability

Incorporating non-electrochemically active elements (such as Zn and Mg) into the framework of active components can enhance structural stability, leading to improved cycling performance. However, limited research has been conducted on the impact of varying doping concentrations. In this study, we conducted a comprehensive analysis of how different levels of Mg doping in Co(OH)
