Summary: High-voltage operation poses a challenge for the stability of battery cathode materials. Previous studies have focused on cycling-induced structural deformation as the main cause of degradation, while ignoring the impact of crystallographic defects introduced during synthesis. Using in situ synchrotron X-ray probes and electron microscopy, the authors have discovered that native lattice strain caused by quenching plays a significant role in the capacity degradation of sodium layered cathodes. The relaxation of this strain leads to structural changes during cycling, which is influenced by temperature and charge/discharge rate.

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.

Summary: All-solid-state lithium sulfide batteries have great potential as next-generation energy storage devices due to their low cost and high energy density. However, their development is limited by the poor conductivity of solid electrolytes and the low electronic conductivity of sulfur. In this study, a highly conductive Li7P3S11 glass-ceramic solid electrolyte is synthesized and used in combination with FeS2 cathode and Li-In anode to fabricate an all-solid-state Li-S battery. The assembled battery exhibits high initial discharge capacities and good capacity retention, particularly at lower temperatures. The differences in electrochemical performance are attributed to the volume variations caused by temperature effects.
