Often touted as the most promising next-generation energy storage systems, lithium (Li) metal batteries have drawn extensive interest due to their energy densities beyond those of Li-ion batteries. The use of Li metal, however, presents a major hurdle since it is susceptible to Li dendrite growths, corrosive interfacial reactions, and uncontrolled volume changes. Li-metal protection is an important issue in overcoming those challenges. In particular, studies have shown that molybdenum disulfide (MoS2) can significantly improve the performance and safety of Li metal batteries when used as a protective coating for anodes, separator modification, and stable interfacial layer between solid-electrolytes and Li metal. Herein, we review the successful implementation of MoS2 for improved Li metal batteries including those of the liquid-type and the solid-state cells. We also provide opportunities and prospects of MoS2 applications for safe and practical Li metal batteries.

Safe solid-state lithium metal batteries (SSLMBs) with high energy density are in great demand for electrical vehicles and large-scale energy storage systems. The interfacial challenges including large interface resistance and untoward reactions have an enormous impact on the rate performance and cycle stability of SSLMBs. Hence, in this work, plastic crystal-based materials are proposed as the interface layers to reduce the interfacial impedance and prevent side reactions between solid electrolytes and Li anode. The plastic crystal-based materials can enable in-situ solidification between solid electrolytes and Li anode and show high ion conductivity of up to [Formula: see text]10[Formula: see text] S ⋅ cm[Formula: see text], high Li ion transference number, and good chemical and electrochemical stability against Li metal, indicating they are suitable to be used as the interface layers for SSLMBs.
