Summary: Solid-state lithium metal batteries with novel solid electrolytes have the potential for high energy density and safety. Sulfide-based argyrodite-class solid electrolytes are attractive due to their excellent ionic conductivity. This study synthesized F-doped argyrodites with dual dopants using a solvent-based approach and found that Li6PS5F0.5Cl0.5 exhibited the highest Li-ion conductivity and cycling performance at room temperature. The enhanced interfacial stability of Li6PS5F0.5Cl0.5 was attributed to the formation of a stable solid electrolyte interphase containing conductive species.

Summary: Li10SnP2S12 is a solid electrolyte with ultrahigh Li-ion conductivity, which shows great potential for solid-state batteries. However, its applications are limited by the high cost of Ge and poor stability. Replacing Ge with Sn significantly reduces the cost while maintaining high conductivity, but the interface stability with high voltage cathodes is still an issue. To address this, a highly conductive Li3InCl6 electrolyte is introduced, leading to superior electrochemical performances at different temperatures.

Summary: Single-crystal nickel-rich materials show excellent structure stability and cycle performance, but high cation mixing in the cathode material negatively affects its electrochemical performance. By regulating the cation mixing, the single-crystal LiNi0.83Co0.12Mn0.05O2 cathode material exhibits high discharge capacity, excellent capacity retention, and superior rate capability. The improved performance is attributed to the reduced cation mixing and integrated single grains, allowing for rapid Li+ transportation within the crystal structure.

Summary: The all-solid-state Li-Se battery shows great potential for next-generation energy storage devices due to its high energy density and safety. However, the low ionic conductivity of the solid electrolytes and large volume changes of Se active materials limit its applications. In this study, a simple solid-state reaction method is used to synthesize a chlorine-rich argyrodite Li5.5PS4.5Cl1.5 electrolyte with high conductivity. Carbon nanotubes are introduced as a host for Se to enhance electronic conductivity and reduce volume expansion. The assembled battery demonstrates excellent performance, with high discharge capacity and long cycling life at different temperatures.

Summary: Sulfide electrolytes with optimized LiI doping in the Li3PS4 structure exhibit high ionic conductivities, making them promising solid electrolytes for all-solid-state batteries. These sulfide electrolytes showed stable capacities and excellent cycling performance at 0 degrees C but experienced fast capacity decay at 60 degrees C. The electrochemical performance differences at different temperatures were attributed to interfacial resistance caused by volume changes. This study provides insights into the temperature effects on the electrochemical performance of all-solid-state Li-S batteries.

Summary: NiTiNb alloys were fabricated through L-PBF with powder mixtures of prealloyed NiTi and elemental Nb powders. The addition of Nb significantly altered the dependence of MTTs on L-PBF process parameters. The net effect of Nb addition is to lower MTTs, while Ni evaporation has the opposite effect. In NiTiNb3 alloys, factors that promote and suppress MTTs are almost completely compensated, resulting in a rather stable MTT despite variations in L-PBF process parameters.
