Electrospinning techniques for inorganic–organic composite electrolytes of all-solid-state lithium metal batteries: a brief review

Abstract

All-solid-state lithium metal batteries (ASLMBs) have attracted considerable attention owing to their high energy density and as they are highly safe. However, as solid inorganic electrolytes (SIEs) and solid polymer electrolytes (SPEs) exhibit poor interfacial compatibility and low ionic conductivity at room temperature, respectively, they seriously hinder the development of ASLMBs. Recently, rigid–flexible coupling inorganic–organic composite solid electrolytes (CSEs) that combine the high ionic conductivity of rigid SIEs and the excellent processing performance of flexible SPEs have been recognized as the most promising solid electrolytes. However, inorganic–organic CSEs have drawbacks such as low ionic conductivity, poor solid–solid interfacial contact, and lithium dendrite growth. In this review, a brief overview of the electrospinning technology, with controllable structural engineering design, adjustable multicomponent materials, and good scalability, widely used for the preparation of inorganic–organic CSEs is provided, and its applications in the syntheses of oxide–polymer, sulfide–polymer, metal-fluoride–polymer CSEs, and advanced nanomaterials (MOF/COF)–polymer CSEs are outlined. Finally, the prospects of using electrospinning for the preparation of inorganic–organic CSEs for lithium metal all-solid-state batteries are discussed.
