Porous thin layered nanosheets assembled ZnCo2O4 grown on Ni-foam as an efficient electrode material for hybrid supercapacitor applications

Binder-free, Ni-foam supported thin layered nanosheets of ZnCo2O4 were successfully fabricated via a surfactant-free hydrothermal method. This desirable thin layered nanosheets of ZnCo2O4 nanoarchitecture grown on Ni-foam exhibited the high specific capacity of 886 C g−1 at 2 mA cm−2 with excellent cyclic stability (103%) for 2000 charge-discharge cycles.185
