Abstract
Research into environmentally friendly energy storage devices is a vital strategy to address the energy crisis and environmental pollution challenges. In this paper, oxygen-rich vacancy Co3O4/NiCo2O4 heterojunction hollow nanocage electrodes were synthesized by a two-step hydrothermal and calcination method. Taking advantage of its unique structure, oxygen vacancies, and the synergistic effect of multi-element transition metal oxides, the electrode has good conductivity, high specific surface area, and abundant active sites. As a result, the Co3O4/NiCo2O4 HHNCs electrode exhibits an ultra-high specific capacitance of 1788F g−1 at 1Ag-1, and the assembled hybrid supercapacitor has an energy density of up to 43.9 Wh kg−1, which is promising for applications in energy storage materials.
