In a given paper, processes of functioning hybrid capacitor, in which positive electrodes are composites Ni(OH)2???С and Ni(OH)2???MoO3???С formed by mechanochemical mixing the relevant components in the ratio of 70:30 and 70:15:15, respectively, and a negative electrode is nanoporous carbon, are studied before and after laser irradiation. The possibility of their joint functioning is shown. The highest specific characteristics are established for a couple of [laser (Ni(OH)2????MoO3???C)]–[C] at a current of 10 mA. AS revealed, the Coulomb efficiency saturates during the first 100 cycles up to 75% for the hybrid system [(Ni(OH)2???C)]–[C], and 94% for the system [laser (Ni(OH)2???MoO3???C)]–[C]. For low frequencies, inclination angle of Warburg of line for hybrid systems [laser (Ni(OH)2???C)]–[C] and [laser (Ni(OH)2???MoO3???C)]–[C] is reduced compared to the system [Ni(OH)2]–[C], indicating the presence of fast reversible redox reactions.
