We thank J. Velázquez, from the C.A.I. de Difracción de Rayos X de la Universidad Complutense de Madrid, for XRD measurements and J.M. Rojo y V. Barranco from Instituto de Ciencia de Materiales de Madrid (CSIC) for the measurements on axsorb electrodes. This research was supported by Repsol under the Inspire program.The need of new systems for the storage and conversion of renewable energy sources is fueling the research in supercapacitors. In this work, we propose a low temperature route for the synthesis of electrodes for these supercapacitors: electrodeposition of a transition metal hydroxide-Ni(OH)₂ on a graphene foam. This electrode combines the superior mechanical and electrical properties of graphene, the large specific surface area of the foam and the large pseudocapacitance of Ni(OH)₂. We report a specific capacitance up to 900 F/g as well as specific power and energy comparable to active carbon electrodes. These electrodes are potential candidates for their use in energy applications.engAtribución-NoComercial-SinDerivadas 3.0 Españajournal articlehttp://dx.doi.org/10.1016/j.diamond.2015.03.003http://www.sciencedirect.comopen access538.9Supercapacitor applicationsElectrochemical capacitorsCarbon nanotubesThin-filmStorageNanoparticlesFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
