Summary: In this study, an ultrafast sintering method using microwave-induced carbothermal shock is reported, which can fabricate various ceramic electrolytes in seconds. Furthermore, it is possible to integrate the electrode and electrolyte in one step by simultaneous co-sintering. Based on this technique, a high areal capacity all-solid-state lithium-metal battery with promising electrochemical performance at room temperature is successfully achieved. This method can also be extended to other solid devices based on ceramic multilayer structures.

Summary: A stable interface and preventing dendrite-growth are crucial for the long-life of solid-state Li batteries using sulfide-based solid electrolytes (SEs) and Li metal anodes. This study reports a strategy using Si doping in Cl-rich argyrodites that enables self-engineered metastable decomposition, leading to the realization of these two factors simultaneously. The metastable Cl atoms react with Li atoms, depleting locally deposited/grown Li crystal nuclei and generating electrically insulated LiCl shells at the grain boundaries. These shells prevent Li redeposition and act as self-protective layers, enabling an ultra-long life ASSLB with Li metal anodes under high current densities at room temperature.

Summary: Halide-based solid electrolytes are gaining interest in solid-state batteries due to their higher electrochemical stability compared to sulfide electrolytes. However, the use of a bilayer separator consisting of a sulfide and a halide is not well understood. This study shows that an electrolyte bilayer improves capacity retention by suppressing interfacial resistance growth. Analytical characterization techniques reveal the chemical incompatibility at the halide and sulfide contact area, emphasizing the importance of considering the chemical compatibility of all components when using halide-based solid electrolytes in solid-state batteries.

Summary: Solid-state lithium metal batteries (SSLMBs) are a promising candidate for next-generation energy storage devices, but the growth of uncontrollable dendritic lithium remains a problem. To address this issue, an integration plasma (IP) strategy is proposed to regulate the surface concentration and atomic ratio of metal elements on the solid-state electrolyte (SSE). The IP-formed interlayer can react with the Li anode to promote spherical and hexagonal Li growth, preventing dendrite propagation.

Summary: In this study, an interdigitated Li-solid polymer electrolyte framework (I-Li@SPE) is designed to enhance the interfacial integrity of all-solid-state batteries. The results show that the 3D Li-SSE interfacial contact in the I-Li@SPE remains smooth and intact after repeated cycling, while the planar contact fails to maintain stability. COMSOL simulation indicates that the I-Li@SPE reduces local current densities by more than 40% and moderates interfacial variation by more than 50%. Consequently, the I-Li@SPE achieves high critical current density and promising high areal capacity cycling. This work presents a new structure for the fabrication of Li-SSE composites and holds great potential for high-capacity solid-state Li batteries.
