High-performance asymmetric supercapacitor based on a CdCO₃/CdO/Co₃O₄ composite supported on Ni foam - part II: a three-electrode electrochemical study.

ABSTRACT: A binder-free CdCO₃/CdO/Co₃O₄ compound with a micro-cube-like morphology on a nickel foam (NF) made via a facile two-step hydrothermal + annealing procedure has been developed. The morphological, structural and electrochemical behavior of both the single compounds constituting this final product and the final product itself has been studied. The synergistic contribution effect of the single compounds in the final compounded resulting specific capacitance values are presented and discussed. The CdCO₃/CdO/Co₃O₄@NF electrode exhibits excellent supercapacitive performance with a high specific capacitance (C _S) of 1.759 × 10³ F g^-1 at a current density of 1 mA cm^-2 and a <
