For single super capacitor materials,each material has its own unique advantages and defects.In this paper,the synthesis of complex multi walled carbon nanotubes with Fe_3O_4 nanoparticles by simple hydrothermal method.Composite performance for Fe_3O_4 nanoparticles adsorbed on carbon nano tube wall composed of reticular structure morphology.Synergy of two component,provides the binary nanometer compound larger specific capacity,excellent properties and good cycle stability.The experimental results proved that the improvement effects of CNT carbon materials on the electrochemical properties of pseudocapacitive electrode material,and CNT/Fe_3O_4 nanocomposites applied to supercapacitor electrode material.
