Silicon (Si) is one of the most promising anode materials for the next generation of lithium-ion battery (LIB) due to its high specific capacity, low lithiation potential, and natural abundance. However, the huge variation in volume during the storage of lithium, along with the low conductivity of element, are the main factors hindering its commercial application. Designing micro–nano structures as well as composites of heterogeneous materials have proven to be effective strategies to overcome these issues. Electrospinning technology is an affordable and scalable method for easily constructing a unique hierarchical micro–nano structure while realizing composites of heterogeneous materials. So far, many efforts have been made to solve the problems of Si-based anodes with general electrospinning. This review considers the technical fundamental and design strategies for electrospun Si-based nanofibers, including preparation processes, structural engineering, and lithium storage performance. The structure–performance relationship of various materials and the effects of compositing with heterogeneous materials are explored in detail. Finally, the remaining challenges are discussed, along with directions for future research. This review will provide inspiration for researchers in the design and manufacture of electrospun Si-based nanofibers for LIBs. |
