Summary: An ultrathin Al film is deposited on the surface of Li(1.5)AI(0.5)Ge(0.5)P(3)O(12) solid state electrolytes (SSEs) by magnetron sputtering, forming a LiAl buffer layer to inhibit side reactions and provide a uniform interfacial electric field. Density functional theory calculations show that the LiAl alloy surface promotes lithium diffusion, inhibiting the formation of lithium dendrites. Assembled all solid state lithium metal batteries with LiFePO4 cathode exhibit improved cycle stability and rate performance.

Summary: Sulfide-based all-solid-state batteries face serious and unavoidable problems in terms of the generation and evolution of electrochemomechanical stresses due to the lack of a liquid electrolyte. In order to understand and address these issues, highly sensitive probing techniques are needed to measure and bridge the relationship between electrochemical reaction process and internal stress evolution. This article provides a brief overview of recent progress in uncovering the origins of internal stresses, stress measurement principles and devices, and the application of stress-measuring techniques in sulfide-based all-solid-state batteries.

Summary: We introduced a garnet-type lithium metal fluoride, Li3Na3M2F12 (M = Al, Sc, In), as solid-state lithium-ion conductors for the first time. The mechanically milled Li3Na3M2F12 compounds crystallized in a cubic garnet-like structure. The ionic conductivities of Li3Na3Al2F12, Li3Na3Sc2F12, and Li3Na3In2F12 are relatively low, but still better than the oxide analogues Li(3)Ln(3)Te(2)O(12) (Ln = Er, Gd, Tb, Nd). Strategies for further improving conductivities of garnet-type Li3Na3M2F12 were also presented.

Summary: Due to its high ionic conductivity, low cost, and excellent air stability, the NASICON-type Li1.5Al0.5Ge1.5(PO)(4) (LAGP) electrolyte is considered a promising candidate for high-performance solid-state batteries. However, the poor interfacial compatibilities between LAGP and lithium metal hinder its commercial application. In this study, a nano multifunctional LiF@Li-zinc (Zn) alloy layer is introduced at the LAGP|Li interface to improve the interfacial stability and homogenize the Li-ion flux. This design leads to stable and tight interface with low resistance, effective inhibition of side reactions, and dendrite-free Li-ion flux.

Summary: Understanding the failure process of solid-state electrolyte (SSE) and providing potential solutions are crucial for the development of solid-state batteries (SSBs). In this study, the dynamic failure process of SSE is observed using in-situ electrochemical SEM, revealing the main origins of continuously generated side-reaction layer and stress-induced cracks. By introducing C3N4 as a modification layer, the interfacial side-reaction is restrained and Li+ flux becomes well-distributed, preventing stress-induced mechanical failure in SSE.

Summary: Superionic conductor LAGP has been widely studied for its high ionic conductivity and stability. However, its application is limited by lithium dendrites and interface instability. By depositing an ultrathin Al film on the surface of LAGP through magnetron sputtering, an Al-LAGP material is formed. In-situ alloying reaction creates a LiAl buffer layer, inhibiting undesired reactions and promoting uniform distribution of the electric field at the interface. Density functional theory calculations show that the LiAl alloy surface facilitates lithium atom diffusion and inhibits dendrite formation. Experimental results demonstrate that Li/Al-LAGP-Al/Li symmetric cells exhibit low resistance and long lifespan, and assembled all solid state lithium metal batteries show improved cycle stability and rate performance.
