| dc.description.abstractEn | Cobalt<sup> </sup>oxides have been extensively used as conductive additives for Ni-MH<sup> </sup>batteries. We report in this paper the performances of an<sup> </sup>original nanometric cobalt oxide, close to Co<sub>3</sub>O<sub>4</sub>, as electrode material<sup> </sup>for hybrid supercapacitors. This spinel type phase contains hydrogen, lithium,<sup> </sup>cobalt vacancies, and especially Co<sup>4+</sup> ions within the structure, leading<sup> </sup>to a high electronic conductivity. Cyclic voltammetry and impedance spectroscopy<sup> </sup>measurements show interesting capacitance (320 F/g in 8M-KOH), as well<sup> </sup>as good electrochemical cycling with a small amount of carbon<sup> </sup>black (5%). | |
