ABSTRACT=<p>Transition metal oxides (TMOs) with spinel structures have a promising potential as the electrode materials for supercapacitors application owning to its outstanding theoretical capacity, good redox activity, and eco-friendly feature. In this work, MnCo<sub>2</sub>O<sub>4.5</sub>@NiCo<sub>2</sub>O<sub>4</sub> nanowire composites for supercapacitors has been successfully fabricated by using a mild hydrothermal approach without any surfactant. The morphology and physicochemical properties of the prepared products can be well-controlled by adjusting experimental parameters of preparation. The double spinel composite exhibits a high specific capacitance of 325 F g<sup>−1</sup> (146 C g<sup>−1</sup>) and 70.5% capacitance retention after 3,000 cycling tests at 1 A g<sup>−1</sup>.</p>
