| Abstract: | Composite polymer fibers with a composition of Si-C-O obtained by electrospinning of precursors solution containing polycarbosilane
or phenol formaldehyde resins with an admix of organic-silicon compounds were synthesized in order to find efficient new electrode
materials for lithium ion batteries. The composition and structure of pyrolized composite fibers were studied by means of
X-ray dispersive analysis and X-ray diffraction, Raman spectroscopy, and by AFM and SEM. It was shown that the composite fibers
(with a diameter of 0.5–1.5 μm) were nanostructured materials with carbon and silicon-oxy-carbide areas about 2–5 nm in size.
A model of the nanostructure of a skeleton for composite fibers synthesized is proposed. |
