Lithium-reservoir-free solid-state batteries can fail due to electrical shorting as a result of fracture and lithium metal filament formation. Mechanical stress at the solid electrolyte surface induce fractures, which promote growth. This arises from both electrochemical sources, electrodeposition, mechanical such external stack pressure. Solid roughness applied pressure together affect development. study combines experiments, 3D synchrotron imaging, mesoscale modeling explore how influences failure mechanisms in free batteries. At low pressure, irregular plating resulting high local current density drive failure. higher uniform is favored; however, notch-like features experience tensile stress, leading fractures that cause premature short-circuiting.

Ag-carbon composite interlayers have been reported to enable Li-free (anodeless) cycling of solid-state batteries. Here, we report structural changes in the Ag-graphite interlayer, showing that on charge, Li intercalates electrochemically into graphite, subsequently reacting chemically with Ag form Li-Ag alloys. Discharge is not reverse charge but rather passes through Li-deficient phases. At higher charging rates, intercalation graphite outpaces chemical reactions Ag, delaying formation phases and resulting more metal deposition at current collector. above 2.5 mA·cm−2, dendrites are suppressed. nanoparticles do suppress effectively than does an interlayer alone. Instead, carbon results homogeneous collector during charge.

Abstract Current lithium (Li)‐metal anodes are not sustainable for the mass production of future energy storage devices because they inherently unsafe, expensive, and environmentally unfriendly. The anode‐free concept, in which a current collector (CC) is directly used as host to plate Li‐metal, by using only Li content coming from positive electrode, could unlock development highly energy‐dense low‐cost rechargeable batteries. Unfortunately, dead Li‐metal forms during cycling, leading progressive fast capacity loss. Therefore, optimization CC/electrolyte interface modifications CC designs key producing efficient batteries with liquid solid‐state electrolytes. Lithiophilicity electronic conductivity must be tuned optimize plating process Li‐metal. This review summarizes recent progress findings design (e.g. 3D structures) its interaction

Abstract Solid‐state electrolytes (SSEs) have attracted extensive interests due to the advantages in developing secondary batteries with high energy density and outstanding safety. Possessing ionic conductivity lowest reduction potential among state‐of‐the‐art SSEs, garnet type SSE is one of most promising candidates achieve performance solid‐state lithium (SSLBs). However, elastic modulus electrolyte leads deteriorated interfacial contacts, increasing electronic conduction at either anode/garnet interface or grain boundary results Li dendrite growth.

Abstract A stable interfacial design bridging Li metal and sulfide solid electrolytes is imperative for deploying practical all‐solid‐state batteries. Despite the extensive exploration of interlayer materials, including inorganic substances, lithiophilic metals, their composites, a comprehensive understanding stability chemo‐mechanical evolution, particularly those influenced by cell fabrication processes, remains unexplored. Herein, it meticulously investigate formation evolution LiF, Mg, conversion‐type multicomponent MgF 2 ultrathin interlayers, each fabricated via thermal evaporation deposition. Unexpectedly, LiF Mg fail to enhance performance, with notably susceptible external pressures during fabrication, leading serious current constriction, while deposition results in Li‐rich solution. Remarkably, coatings demonstrate substantially superior performance both Li|Li 6 PS 5 Cl|Li symmetric cells (up 2000 h) LiNi 0.70 Co 0.15 Mn O |Li full‐cells (82% capacity retention after 800 cycles) at 30 °C.
