Progress and perspectives on electrospinning techniques for solid‐state lithium batteries

Abstract

Solid‐state electrolytes (SSEs), being the key component of solid‐state lithium batteries, have a significant impact on battery performance. Rational materials structure and composition engineering on SSEs are promising to improve their Li+ conductivity, interfacial contact, and mechanical integrity. Among the fabrication approaches, the electrospinning technique has attracted tremendous attention due to its own merits in constructing a three‐dimensional framework of SSEs with precise porosity structure, tunable materials composition, easy operation, and superior physicochemical properties. To this end, in this review, we provide a comprehensive summary of the recent development of electrospinning techniques for high‐performance SSEs. Firstly, we introduce the historical development of SSEs and summarize the fundamentals, including the Li+ transport mechanism and materials selection principle. Then, the versatility of electrospinning technologies in the construction of the three main types of SSEs and stabilization of lithium metal anodes is comprehensively discussed. Finally, a perspective on future research directions based on previous work is highlighted for developing high‐performance solid‐state lithium batteries based on electrospinning techniques.

Recent Advances and Future Perspectives of PVDF-Based Composite Polymer Electrolytes for Lithium Metal Batteries: A Review

“…The pore configuration of the electrostatic spinning film can accelerate the migration of Li + , which makes it difficult for polymer molecular chains and inorganic salts to form crystalline regions. − As a result, electrostatic spinning can be a more efficient CPE preparation process than solution casting. The preparation of CPE fibers by electrostatic spinning is generally influenced by a few elements, like the polymer’s molecular weight size and distribution, solution concentration, applied voltage, propulsion rate, and receiving distance . By optimizing the solution and electrostatic spinning process parameters, the fiber filament shape may be precisely adjusted, resulting in improved contact between CPEs and the interface.…”

Advances in Electrospun Materials and Methods for Li-Ion Batteries

“…Additionally, the electrospinning method can be used to create nanofiber composites that are doped [ 27 ], encapsulated [ 28 ], porous [ 29 ], or bendable as well. Despite these advances, there are still limitations to the sustainability and efficiency of nanofibers in LIBs, prompting ongoing research for improvements [ 30 ]. In addition to reusing or recycling components, it may be worth exploring the extraction of raw materials from sustainable bioresources such as biomass.…”
