Summary: Researchers developed a carbon-fiber-supported liquid Na-K alloy anode to enhance the contact between the anode and electrolyte in rechargeable solid-state Na metal batteries (SSNMB). By using cryogenic transmission electron microscopy (cryo-TEM), they characterized the evolution of the solid-electrolyte interphase (SEI) and identified both crystalline and amorphous phases that facilitate ion transport and prevent side reactions. The enhanced contact between Na-K alloy and solid-state electrolyte enables long cycle stability and high critical current density.

Summary: Metal solid-state batteries are considered the next-generation energy storage systems with high energy density and high safety. A strong and intimate solid-state interfacial contact between sodium metal and solid-state electrolyte is crucial for good cyclic stability at high current density. Inorganic electrolytes suffer from poor stability when cycled at low current density, leading to dendrite formation and loss of solid-solid contact at the interface. Further research and engineering approaches are needed to improve the integration of sodium metal with solid-state electrolytes and enhance electrochemical performance.

Summary: By using cryo-atom probe tomography, we have discovered the degradation process between the liquid electrolyte and Si electrode. We found that the Si electrode corrodes before the charge-discharge cycles begin, and the delithiation process leads to the formation of nanograins. These nanograins are pulverized into nanoscale fragments that float in the electrolyte. The electrolyte also decomposes during this process. Understanding these microstructures is crucial for understanding the degradation of Si anodes and can potentially inform the design of new batteries.

Summary: The elucidation of lithium ion transport pathways through a solid electrolyte separator is important for the development of all-solid-state batteries. Neutron imaging was performed on an all-solid-state lithium-sulfur battery using an increased Li-6 content in the anode. This allowed for differentiation between the mobile lithium ions diffusing through the cell and those initially located in the solid electrolyte, and demonstrated the lithium ion diffusion through the cell and the distribution of trapped lithium ions in charged and discharged states.

Summary: In this study, neutron imaging was used to visualize and study invasion phenomena in fibrous porous transport layers (PTLs) of titanium felt under different flow conditions of gas and liquid phase. The invasion process was characterized by counter-current flow of water and air with joint imbibition and drainage processes. Neutron radiography and tomography were used to visualize the dynamics and study the static gas-liquid distributions. The results showed that the invasion occurred in repeated imbibition/drainage cycles, with frequencies depending on the flow conditions and the PTL structure.

Summary: The low rate-capability of solid-state lithium-sulfur batteries is a major obstacle to their development. Neutron imaging has revealed that sluggish ion transport within the composite cathode is the main reason for this limitation. Furthermore, concentrated lithium near the current collector, discovered through state-of-charge-dependent tomography, indicates a previously overlooked loss mechanism caused by sluggish ion transport.

Summary: By utilizing cryo-atom probe tomography, we have identified the degradation mechanisms of the liquid electrolyte, Si electrode, and their interface. The corrosion of the Si anode results from the decomposition of Li salt even before charge-discharge cycles. Volume shrinkage during delithiation leads to the formation of nanograins through recrystallization. These newly formed grain boundaries facilitate the pulverization of nanoscale Si fragments, some of which float in the electrolyte. Phosphorus is segregated to these grain boundaries, confirming the decomposition of the electrolyte. These findings contribute to an understanding of the self-catalyzed/accelerated degradation of Si anodes and can inform the development of new battery designs that are unaffected by these limiting factors.
