Uniform MnCo₂O_4.5 porous nanowires and quasi-cubes for hybrid supercapacitors with excellent electrochemical performances.

ABSTRACT: In this work, uniform MnCo₂O_4.5 nanowires (NWs) on stainless steel foil (SSF) were prepared through a facile, cost-efficient, and eco-friendly hydrothermal method at 120 °C with a post-calcination process in air. The microstructure of MnCo₂O_4.5 samples could be tuned at different hydrothermal temperatures and quasi-cubes (QCs) were obtained in high yield at 150 °C. The MnCo₂O_4.5 NW powder peeled off from the SSF delivered an outstanding capacity of 248.62 C g^-1 at 1 A g^-1 with a capacity preservation of 179.43 C g^-1 at 8 A g^-1, while the QCs exhibited 177.19 and 111.73 C g^-1, respectively. To assess the possibility of its actual applications, a hybrid supercapacitor (HSC
