Recent Advances in Electrospun Metal Chalcogenide Anodes for Lithium-Ion and Sodium-Ion Batteries

Abstract

Metal chalcogenides have been considered as one kind of the most promising anodes for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to their high capacities, thermal stabilities, and low price. However, the natural poor conductivity and large volume expansion of metal chalcogenides leading to a rapid capacity deterioration seriously makes them difficult for commercial applications. A 1D carbon-source nanostructure based on electrospinning can perfectly address the issues because of its cost-effectiveness, versatility, and controllability. Herein, we present a comprehensive review of the development of a metal chalcogenide nanomaterial by electrospinning for LIBs and SIBs. By subdividing various metal chalcogenide active materials, this Review focuses on the evolution in architectonics and the component of electrospun electrode materials. Particularly, the current progress of electrospun metal oxides, metal sulfides, and metal selenides materials of LIBs and SIBs has been appropriately discussed, respectively. Finally, the outlook of electrospun metal chalcogenide materials is also given. In the near future, the high-performance metal chalcogenide anodes via electrospinning will play an effective role in the promotion and application of LIBs and SIBs. Further, other advanced energy-storage devices can also draw on the experience from the design and fabrication of electrospun hierarchical materials.
