Enhanced Electrochemical Performance

Novelty Cu2O multi-branched nanowires and nanoparticles with size ranging from [Formula: see text]15[Formula: see text]nm to [Formula: see text]60[Formula: see text]nm have been synthesized by one-step hydrothermal process. These Cu2O nanostructures when used as anode materials for lithium-ion batteries exhibit the excellent electrochemical cycling stability and reduced polarization during the repeated charge/discharge process. The specific capacity of the Cu2O nanoparticles, multi-branched nanowires and microscale are maintained at 201.2[Formula: see text]mAh/g, 259.6[Formula: see text]mAh/g and 127.4[Formula: see text]mAh/g, respectively, under the current density of 0.1[Formula: see text]A/g after 50 cycles. The enhanced electrochemical performance of the Cu2O nanostructures compared with microscale counterpart can be attributed to the larger contact area between active Cu2O nanostructures/electrolyte interface, shorter diffusion length of Li[Formula: see text] within nanostructures and the improved stress release upon lithiation/delithiation.

Si/carbon nanofibers (Si/CNFs) composite used as the anode materials of lithium-ion battery have been prepared via electrospinning and calcinations treatment. Hydrofluoric acid is used to remove surface oxides of Si particles. SEM observation indicates that silicon particles are uniformly embedded in the carbon nanofibers. X-ray diffraction (XRD), energy dispersive x-ray spectroscopy (EDX) and Raman scattering have been used to analysis the composition and phase of the composite materials. The first reversible capacity of the Si/CNFs composite is 1004 mAh/g, and 390 mAh/g has been remained after 100 cycles. Such Si/CNFs composite could be a promising anode material in lithium ion batteries.
