Engineering cationic vacancies on sphere-like zinc cobaltite microstructures via self-assembly of silkworm-like interconnected nanoparticles for battery-type supercapacitors

Cationic (Zn) vacancies were introduced into ZnCo2O4 microspheres via solvothermal synthesis method. These vacancies improved the electrochemical performance of ZnCo2O4 when utilized as electrode material in battery-type supercapacitors.
