Strategies to regulate the interface between Li metal anodes and all-solid-state electrolytes

Abstract

All-solid state lithium metal batteries (ASSLMBs) with high energy density using lithium metal anodes (LMAs) and high safety all-solid-state electrolytes (ASSEs) are considered as a good choice for the next generation electrochemical energy storage devices. However, there are many challenges for their practical applications, especially the issues of the ASSE–LMA interface. In this review, the problems arising from the combination of LMAs and ASSEs and their modification strategies are summarized. We first introduce the current characterization techniques for the interface. Then the existing problems at the interface and analysis of the causes of these problems are presented. In addition, strategies to regulate the interface based on these problems are summarized. Finally, some further research directions for the interfaces of ASSLMBs are pointed out.
