A Mini-review: Electrospun Vanadium-Based Materials for Lithium-Ion Batteries

Vanadium-based materials like vanadates and vanadium oxides have become the preferred cathode materials for lithium-ion batteries, thanks to their high capacity and plentiful oxidation states (V2+-V5+). The significant challenges such as poor electrical conductivity and unstable structures limit the application of vanadium-based materials, particularly vanadium oxides, since stable nanowire electrode materials have the capacity to adjust to their own volume expansion or contraction and offer short radial ion diffusion paths during cycling. This review first summarizes various vanadium-based nanowires prepared by electrospinning technology, and next generalizes the various modification methods (morphology design, crystal structure modulation, as well as in situ carbon complexation) of one-dimensional nanowire vanadium oxide materials obtained by electrospinning technology, and the vanadium oxide materials synthesized by other techniques. In comparison, the challenges and prospects of the development of one-dimensional nanowire materials are discussed in detail.
