Review on electrospinning anode and separators for lithium ion batteries

Lithium-ion batteries (LIBs) are widely used in electronic devices and electric vehicles. With the increasing demand for lithium-ion batteries, it is necessary to develop safe LIBs with high energy density. Nanofibers prepared by electrospinning have many advantages, including small diameters, large specific surface area, small pore sizes, high porosity, and good pore connectivity. Therefore, electrospun nanofibers are extensively used in energy-related applications, while electrospun films exhibit excellent ductility and can be potentially utilized in flexible batteries. This paper focuses on the recent advances in electrospinning nanomaterials for the anodes and separators of LIBs. In addition, electrospinning can be performed to produce materials for sodium/potassium-ion batteries and solid-state batteries. Finally, the commercialization of electrospinning technology and prospects of battery industrialization as well as the future development of LIBs and other alternative materials are discussed.
