Mesoporous ZnCo 2 O 4 nanoflakes grown on nickel foam as electrodes for high performance supercapacitors
ZnCo 2 O 4 nanoflakes, as electrodes for supercapacitors, are grown on a cellular nickel foam using a cost-effective hydrothermal procedure. The mesoporous ZnCo 2 O 4 nanoflakes have large electroactive surface areas with strong adhesion to the Ni foam, allowing fast ion and electron transport. The...
