A porous carbon spheres@MnO₂ composite is prepared and used as the electrosorption electrode. The MnO₂ nanoparticles are evenly distributed on the porous carbon spheres. The as-prepared composite possesses high specific surface area of 258.6 m²•g⁻¹. Its electrochemical evaluations confirm that the composite has high specific capacitance of 175 F•g⁻¹ at a current density of 1 A•g⁻¹ in 0.5 mol•L⁻¹ NaCl aqueous solution, and shows good conductivity and excellent cycling performance. Electrosorption capacity for the porous carbon spheres@MnO₂ composite is 6.28 mg•g⁻¹. Moreover, the composite electrode exhibits excellent recyclability with an efficient regeneration process.
