摘要：
An effective interfacial strategy, which should have tailorable volumetric stability and adaptive affinity, is the key to overcome the big challenge of poor and unstable interfacial contact faced by solid-state lithium batteries. Here, we report a smart viscoelastic liquid-metal-based layer to stabilize the lithium/LAGP interface, which can reversible dynamic-transmit between liquid metal and solid lithium alloy. The resulted co-existence of such mix-phase endow the interfacial layer durable electronic-ionic conductive capability with adaptive deformability to response the system stresses. A high reversible strain storage capability of 83 % was observed by electrochemical Raman device and nano-indentation for such solidify/liquify lithiated liquid metal (LLM) mix-phase layer. With prominent merits in both fluidity and electron/ionic conductivity, the as-fabricated LLM layer guarantees extraordinary interfacial stability, which enables a radically decreased resistance of lithium/LAGP electrolyte from 2000 Ω to 520 Ω. Of particular, with the deformability of the LLM layer, the assembled symmetric cell delivered an ultra-long lifespan over 4500 h and stable durability. This work affords the creative construction of a viscoelastic liquid-metal-based layer for appropriate phase variation and prolonged contact stability towards interfacial reliability, leading to enormous prospects in developing solid-state lithium batteries. © 2025
