Abstract:Background: Many studies on the electrochemical properties of electrospun nanofiber in
lithium-ion batteries (LIBs) have been performed. To the best of our knowledge, no work has yet
summarized the use of electrospun one-dimensional materials as anode materials and also assessed
the influence of this unique morphology on the properties of LIBs properties. This review describes
recent advances in the synthesis and characterization of a variety of 1D multifunctional oxides, oxide
composites and oxide-carbon composites electrospun nanofibers used as anodes in LIBs, which provide
both excellent capacity and high mechanical integrity.
Method: Oxide, oxide composite and oxide-carbon composite electrospun nanofibers are reviewed
as anodes in LIBs. For each material type, we report on the structural and electrochemical properties,
and also discuss how to control the structures of the resulting materials and improve the electrochemical
performance characteristics (e.g., capacity, cycle life, and rate capability). We apply correlation
method and step-to-step focusing method to present the references.
Results: 176 papers were included in the review; 6 tables and 7 figures are shown in this paper. The
manuscript is divided into 5 parts. For the electrospinning parameters of nanofibers, different conditions
were compared, such as polymer, solvent, polymer concentration, voltage level, and tip-tocollector
distance. The processing conditions of electrospun oxides nanofibers are also discussed,
including the oxide precursor, solvent, voltage level, calcination temperature/heating rate. The performance
of electrospun oxide nanofibers as electrodes in LIBs are summarized including metal
oxide- metal, metal oxide- metal oxide, and metal oxide-carbon composites.
Conclusion: The findings of this review confirm that prepared electrospun electrode materials tend
to form 3D interconnected networks, which can enhance electrochemical activities of electrode materials
via facilitating electronic/ionic transfers. The electrochemical performance of electrospun
MexOy nanofibers depends on process parameters and also the component structure such as metalembedded,
carbon coated/doped, and metal oxide hybrid material. However, the electrospun MexOy
nanofibers require additional development before commercial application. To utilize the described
materials as effective anodes in commercial LIBs, especially for electric vehicle applications, additional
research work is required.
