Herein, a novel composite material of coupled carbon fibers and Co1.5Mn1.5O4 spinel oxide crystals has
been fabricated by a facile twoͲstage process. In the first stage, fibers were produced by singleͲspinneret
electrospinning of polymer solutions with the cobalt and manganese acetate precursors. In the second stage, fibers
were heatͲtreated to convert them into composite structure. Scanning electron microscopy (SEM) analysis confirmed
the formation of composite fibers with spinel crystals deposited on the surface. Scanning transmission electron
microscopy (STEM) and energy dispersive XͲray spectroscopy (EDS) analysis of composite fibers crossͲsection revealed
that carbon occupies space inside spinel rings. The composite electrode delivers a specific capacity of about 740 mAh
g
–1, at a current density of 5 A g–1 in alkaline solution, which is more than 37 times superior to neat carbon fibers.
Furthermore, the electrode retained 135% of its initial capacity, after 1000 cycles ...of galvanostatic charge/discharge at
5 A gо1.
