ZIF-67-derived NiCo2O4@Co2P/Ni2P honeycomb nanosheets on carbon cloth for high-performance asymmetric supercapacitors

NiCo 2 O 4 @Co 2 P/Ni 2 P-CC, for the first time, was prepared using ZIF-67 as sacrificial templates through 4 steps procedure. Based on honeycomb structures, NiCo 2 O 4 @Co 2 P/Ni 2 P-CC electrode shows high areal capacitance and excellent cycle stability.
