AB  - We herein report a simple two-step procedure for fabricating tetragonal CoMn2O4 spinel nanocrystals on carbon fibers. The battery-type behavior of these composite fibers arises from the redox activity of CoMn2O4 in an alkaline aqueous solution, which, in combination with the carbon fibers, endows good electrochemical performance and long-term stability. The C"CoMn2O4 electrode exhibited high specific capacity, up to 62 mA h g(-1) at 1 A g(-1) with a capacity retention of around 90% after 4000 cycles. A symmetrical coin-cell device assembled with the composite electrodes delivered a high energy density of 7.3 W h kg(-1) at a power density of 0.1 kW kg(-1), which is around 13 times higher than that of bare carbon electrodes. The coin cell was cycled for 5000 cycles with 96.3% capacitance retention, at a voltage of up to 0.8 V, demonstrating excellent cycling stability.

AB  - We report a mesoporous composite system consisting of carbon fiber cores surrounded with Co1.5Mn1.5O4 spinel nanocrystal shells, synthesized by a simple two-step process involving single-nozzle co-electrospinning and subsequent calcination. Benefiting from the obtained core-shell structure, this composite has exhibited high specific capacitance in the two-electrode configuration, up to 384 F g(-1) at 0.28 A g(-1), with no capacitance loss after 2000 cycles at 50 mV s(-1). The incorporation of spinel nanocrystals improved the capacitive performances of composite fibers due to a synergistic effect of redox-active shells and the conductive cores, making this novel material promising for symmetrical supercapacitors.
