Summary: This study presents a new method for synthesizing lead-free perovskite nanocrystals. The method involves a post-synthetic transformation reaction of Cs3BiX6 (X = Cl, Br) zero-dimensional perovskite nanocrystals under mild conditions to produce lead-free double and quadruple perovskite nanocrystals. The produced nanocrystals exhibit good particle uniformity, high crystallinity, and comparable optical properties to the directly synthesized nanocrystals. The study provides valuable insights into the crystal structures, excitonic properties, and their relationships of perovskite nanocrystals.

Summary: Thin-film solid-state metal dealloying is a promising technique for designing nanostructured thin films with diverse applications. The morphological, structural, and chemical evolution of Ti-Cu thin films prepared by SSMD using Mg as the solvent were studied using synchrotron X-ray spectroscopy, diffraction, and electron-based spectroscopy and imaging. The relationship between processing and structure was analyzed in relation to parent alloy composition, dealloying temperature, and time. Morphological transitions and the dealloying rate were found to be influenced by the parent alloy composition. The study provides fundamental insights into thin-film SSMD and offers opportunities for the suppression of undesired intermetallic phases in certain alloy systems.

Summary: The effects of cation and anion substitution on the electrochemical properties of KVPO4F cathodes were investigated in this study. It was found that both substitutions resulted in smoother voltage profiles and reduced charging time at high voltage. Additionally, it was discovered that ionic substitution enabled intercalation of excess K ions at a reasonably high voltage. The use of a pre-reacted precursor in the synthesis reaction pathways was also found to create detours, which can be used to optimize the performance of KVPO4F and related compositions for K-ion batteries.

Summary: Halide-type solid electrolytes (SEs) show promise as Li+ conductors for all-solid-state lithium batteries (ASSLBs), but poor compatibility with metal anode remains an issue. In this study, a dual-halogen trigonal SE, Li2ZrCl6-xFx, is developed with high ionic conductivity and moisture stability. ASSLBs with this SE and LiCoO2 cathode materials exhibit excellent electrochemical performance, attributed to the formation of an in-situ protective layer between the SE and Li alloy. The development of mixed halogen-based SEs provides a cost-effective strategy to improve the stability of halide SEs and promote the application of high-voltage ASSLBs.

Summary: An advanced synchrotron-based in situ X-ray diffraction (XRD) technique is developed and used to track and monitor the real-time formation and phase selection of cobalt (Co) in electrodeposition, confirming the computational results obtained using DFT. The effects of controlling factors such as the electrolyte pH and deposition overpotential are systematically investigated, revealing that the phase of the electrodeposited Co is controlled by both thermodynamics and kinetics. The experimental results agree with the nanometric phase diagram computed with DFT, and layer-by-layer alternative stacking of fcc-hcp polymorphic phases can be easily achieved by adjusting the overpotential.

Summary: Solid-state electrolytes (SSEs) are critical to the advancement of cutting-edge all-solid-state batteries (ASSBs), and their ionic conductivity is influenced by the presence of amorphous and crystalline phases. This study investigates the impact of amorphization on the ionic conductivity of a binary xLi(2)S-(100-x)LiI system using mechanochemical milling synthesis. Powder X-ray diffraction (PXRD) reveals that the stoichiometry of Li2S and LiI significantly affects the amorphization of the system. Electrochemical impedance spectroscopy (EIS) analysis shows that the amorphization of the system is closely related to its ionic conductivity, primarily due to the effect of grain boundary resistance. These findings provide insights into the design of innovative amorphous SSEs.
