Interface Layers

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.

Solid State Electrolytes

Solid-state lithium metal batteries (LMBs) have become increasingly important in recent years due to their potential to offer higher energy density and enhanced safety compared to conventional liquid electrolyte-based lithium-ion batteries (LIBs). However, they require highly functional solid-state electrolytes (SSEs) and, therefore, many inorganic materials such as oxides of perovskite La2/3−xLi3xTiO3 (LLTO) and garnets La3Li7Zr2O12 (LLZO), sulfides Li10GeP2S12 (LGPS), and phosphates Li1+xAlxTi2−x(PO4)3x (LATP) are under investigation. Among these oxide materials, LLTO exhibits superior safety, wider electrochemical window (8 V vs. Li/Li+), and higher bulk conductivity values reaching in excess of 10−3 S cm−1 at ambient temperature, which is close to organic liquid-state electrolytes presently used in LIBs. However, recent studies focus primarily on composite or hybrid electrolytes that mix LLTO with organic polymeric materials. There are scarce studies of pure (100%) LLTO electrolytes in solid-state LMBs and there is a need to shed more light on this type of electrolyte and its potential for LMBs. Therefore, in our review, we first elaborated on the structure/property relationship between compositions of perovskites and their ionic conductivities. We then summarized current issues and some successful attempts for the fabrication of pure LLTO electrolytes. Their electrochemical and battery performances were also presented. We focused on tape casting as an effective method to prepare pure LLTO thin films that are compatible and can be easily integrated into existing roll-to-roll battery manufacturing processes. This review intends to shed some light on the design and manufacturing of LLTO for all-ceramic electrolytes towards safer and higher power density solid-state LMBs.
