Abstract

Ultrathin Co-Co(OH)₂ composite nanoflakes have been fabricated through electrodeposition on 3D nickel foam. As electrochemical capacitor electrodes, they exhibit a high specific capacitance of 1000 F g^-1 at the scan rate of 5 mV s^-1 and 980 F g^-1 at the current density of 1 A g^-1, respectively, and the retention of capacitance is 91% after 5000 cycles.
