Progress and perspectives on the development of inorganic nanofibres/nanowires for functional electrolytes of solid-state lithium metal batteries

Abstract

All solid-state lithium batteries (ASSLBs) have high safety and high energy density, and thus, are considered one of the most promising directions for battery development. However, solid-state electrolytes (SSEs), as the key components of ASSLBs, are associated with some issues such as high interfacial impedance at room temperature and serious lithium dendrite growth. In this case, the application of inorganic nanofibers/nanowires to modify the structure and function of SSEs is an effective strategy to improve the ionic conductivity of the electrolyte, enhance the interfacial stability between the electrodes/electrolyte, and solve the above-mentioned problems encountered in ASSLBs. This review provides a comprehensive summary of the latest applications of inorganic nanofibers/nanowires in SSEs for high-performance lithium-metal batteries, focusing on the basic principles of lithium-ion transport, high-voltage and high-pressure resistance stability and anode protection in SSEs for lithium-metal batteries. Moreover, the common methods currently employed for the preparation of inorganic nanofibers/nanowires and the relevant applications of inorganic nanofibers in SSEs for lithium-metal batteries are systematically summarized based on the classification of the fillers used in inorganic nanofibers/nanowires. Finally, future research directions are proposed to address all the challenges in the application and commercialization of this technology. This review aims to provide timely and important guidance for the development and application of inorganic nanofibers/nanowires in high-performance SSEs.
