Abstract
Nanofibers (NFs) and composite NFs have been widely used as electrode and separator materials in lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to their high surface-area-to-volume ratio and versatility of their morphologies. The majority of carbon-fibers (CFs) anodes have been prepared by electrospinning and subsequent thermal treatment. Nevertheless, the low fiber yield and safety hazards associated with this method have raised concerns and limited the commercialization of composite CF anodes. Fiber and nanofiber processing methods such as centrifugal spinning can overcome low productivity and eliminate the use of a high voltage to produce fibers. In the present work, centrifugally spun fibers with alloying, transition metal oxides, and transition metal sulfite-based materials are presented and discussed for potential use as anode materials in LIBs and SIBs. Emphasis is given on the centrifugal spinning process and its effects on fiber formation, morphology, and structure of these nanocomposite anodes.
