AbstractThe coupling of solid-state electrolytes with a Li-metal anode and state-of-the-art (SOA) cathode materials is a promising path to develop inherently safe batteries with high energy density (>1000 Wh L−1). However, integrating metallic Li with solid-electrolytes using scalable processes is not only challenging, but also adds extraneous volume since SOA cathodes are fully lithiated. Here we show the potential for “Li-free” battery manufacturing using the Li7La3Zr2O12 (LLZO) electrolyte. We demonstrate that Li-metal anodes >20 μm can be electroplated onto a current collector in situ without LLZO degradation and we propose a model to relate electrochemical and nucleation behavior. A full cell consisting of in situ formed Li, LLZO, and NCA is demonstrated, which exhibits stable cycling over 50 cycles with high Coulombic efficiencies. These findings demonstrate the viability of “Li-free” configurations using LLZO which may guide the design and manufacturing of high energy density solid-state batteries.

All-solid-state batteries (ASSBs) have attracted much attention in recent years, due to their high energy density, excellent cycling performance, and superior safety property. As the key factor of all-solid-state batteries, solid electrolyte determines the performance of the batteries. Garnet-typed cubic Li7La3Zr2O12(LLZO) has been reported as the most promising solid electrolyte on the way to ASSBs. Thin film electrolyte could contribute to a higher energy density and a lower resistance in a battery. This short review exhibits the latest efforts on LLZO thin film and discusses the different preparation methods, together with their effects on characteristics and electrochemical performances of the solid electrolyte film.

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.
