摘要

Abstract

In this work

a new ZnO/CoNiO

/CoO/C metal oxides composite is prepared by cost-effective hydrothermal method coupled with annealing process under N

atmosphere. Notably

the oxidation-defect annealing environment is conducive to both morphology and component of the composite

which flower-like ZnO/CoNiO

/CoO/C is obtained. Benefited from good chemical stability of ZnO

high energy capacity of CoNiO

and CoO and good conductivity of C

the as-prepared sample shows promising electrochemical behavior

including the specific capacity of 1435 C·g

-1

at 1 A·g

-1

capacity retention of 87.3% at 20 A·g

-1

and cycling stability of 90.5% for 3000 cycles at 5 A·g

-1

respectively. Furthermore

the prepared ZnO/CoNiO

/CoO/C/NF//AC aqueous hybrid supercapacitors device delivers the best specific energy of 55.9 W·h·kg

-1

at 850 W·kg

-1

. The results reflect that the as-prepared ZnO/CoNiO

/CoO/C microflowers are considered as high performance electrode materials for supercapacitor

and the strategy mentioned in this paper is benefit to prepare mixed metal oxides composite for energy conversion and storage.
