Recent advances in electrospun one-dimensional carbon nanofibers structures/heterostructures as anode materials for sodium ion batteries

Abstract

As promising candidates for large-scale energy storage systems, sodium ion batteries (SIBs) are limited by relatively lower energy density. This shortcoming necessitates the design of high specific capacity, excellent cycling durability, yet low-cost anodes. Here, we review one-dimensional strutural/heterostructural carbon nanofibers (CNFs), which are generally synthesized via a simple, low cost, and scalable electrospinning technology, as a basis for developing anode materials for SIBs. The rational design in the structure and chemistry of CNFs, including constructing cross-link structure and porous structure as well as heteroatom doping, is described, followed by illustrations of how a robust understanding of CNFs as the carbon matrix within heterostructures provides fundamental insights into electronic conductivity, electrochemical activity and cycling stability in anode materials with high theoretical capacities (alloys and metal chalcogenides). Based on the insights, we conclude the future perspectives on the critical issues, challenges and research directions of designing one-dimensional carbon nanofibers based materials via electrospinning.
