Ni nanorods prepared by electrochemical growth through an anodized aluminiumoxidemembranewere used as substrate for the electrodeposition of MnO2 either in potentiostatic mode or by a pulsedmethod. Electrochemical deposition parameters were chosen for an homogeneous deposit onto Ni nanorods. ResultingNi supportedMnO2 electrodeswere tested for(More)
This paper presents a new type of capacitor and deals with a hybrid approach where the advantages of two systems, dielectric capacitors and the ultracapacitor are combined. The objective is to increase the capacitance and the energy storage capability, while or at least preserving or decreasing the volume of the passive components. In this aim, the surface(More)
A new hybrid approach consists to use the advantages of both systems namely the high geometric aspects of the electrodes of the ultracapacitor and the high dielectric strength of polymer materials used in dielectric capacitors. The surface roughness of the electrodes of the ultracapacitor is manufactured with nano-porous materials; activated carbon and(More)
