Synthesis and interface modification of oxide solid-state electrolyte-based all-solid-state lithium-ion batteries: Advances and perspectives

All-solid-state Li-ion batteries (ASSLiBs) are considered as promising next-generation energy storage devices, and the one that is based on oxide ceramic solid-state electrolyte (SSE) has attracted much attention for its high safety and stability in ambient conduction compared with that of used sulfur and polymer SSEs. However, the undeformable nature of the ceramic SSEs brings new issues such as poor interface bonding, limited contact area and limited cathode utilization for the ASSLiBs. In addition, the interface reaction and resistance are also obstacles for ASSLiBs application. In this review, we focus on the synthesis and electrochemical properties, interface modification and failure mechanism of ASSLiBs. Finally, perspectives of future researches on the ceramic SSEs-based ASSLiBs are discussed.

Automated summary

All-solid-state Li-ion batteries based on oxide ceramic solid-state electrolyte are considered promising for their high safety and stability, but the undeformable nature of ceramic electrolyte can lead to issues such as poor interface bonding, limited contact area, and limited cathode utilization. Interface reaction and resistance also pose obstacles for the application of ASSLiBs. The review focuses on synthesis, electrochemical properties, interface modification, and failure mechanism of ASSLiBs, and discusses future research perspectives on ceramic SSEs-based ASSLiBs.
