For comparative purposes, an electrode made of commercial Ni foam was also prepared. The foam-based electrodes were paired with a carbon cloth electrode and used to assemble asymmetric electrochemical cells. The electrochemical response of these cells was studied by applying different electrochemical techniques. In addition, two different protocols (cycling and floating) were applied to assess cells durability and fade. Despite the significant differences in the decorated foams morphology and structure their electrochemical responses revealed similar trends. The electrodes made of tailored foams showed higher specific capacitance, better capacitance retention at high current load and enhanced cycling stability compared to the electrodes made of commercial foam. The asymmetric cells made with the tailored foams revealed higher (maximum) specific energy (11\u201314 Wh kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    ) and specific power (1.3\u20131.4 \u00d7 10\n                    <jats:sup>4<\/jats:sup>\n                    W kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    ) compared to cells assembled with commercial foams (8.4 Wh kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    and 6.3 \u00d7 10\n                    <jats:sup>3<\/jats:sup>\n                    W kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    ).
