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.
通过在三维泡沫镍上进行电沉积制备了超薄Co-Co(OH)₂复合纳米片。作为电化学电容器电极，它们在扫描速率为5 mV s⁻¹时表现出1000 F g⁻¹的高比电容，在电流密度为1 A g⁻¹时分别为980 F g⁻¹，并且在5000次循环后电容保持率为91%。
