Abstract:

The composite electrode material using nano-Zn-doped MnO_x synthesized by the sol-gel method and activated carbon(AC) nano-particles obtained by roller vibration milling at room temperature was prepared.The microstructure and the electrochemical performance of the composite electrode material were studied with the AFM，XRD and electrochemical methods.The activated carbon nano-material showed spherical shape with 50 nm mean size and slit structure involving micro-pores and meso-pores.XRD and pre-surface analysis showed average pore size of the Zn-doped MnO_x nano-material was less 30 nm and mesopore dominates over porous structure.Meanwhile the AC nano-particles combined with 10%（mass） Zn-MnO_x material possessed improved electrochemical property with specific capacitance up to 299 F·g^-1.
