Establishing highly-efficient surface faradaic reaction in flower-like NiCo2O4 nano-/micro-structures for next-generation supercapacitors

As in the case of supercapacitors, spinel NiCo2O4 shows the main drawbacks of objectionable pseudocapacitive mechanism, low-voltage polarization effect and confined ion-reaction dynamics, which result in constrained development, narrow work voltage, and low loading mass. Herein we combined two strat...
