Summary: To achieve high energy density in fluoride-ion batteries, it is necessary to develop better cathode materials. Hydrogen storage alloys such as LaNi5 show promise as candidates for cathode materials, as they can be fluorinated and provide good conductivity. Through atomic-resolution scanning transmission electron microscopy, it was observed that LaNi5 particles decompose into LaF3 and Ni nanocrystals during the charge process, forming a nano-scale network that maintains ion conductivity. This suggests that intermetallic alloys containing two function-sharing elements could be useful in exploring higher capacity cathodes for fluoride-ion batteries.

Summary: Impurity doping is an effective method to control the functional properties of materials, but it can significantly alter material properties when the dopants segregate to grain boundaries. In this study, the researchers investigated the structural transformation of alpha-Al2O3 grain boundaries induced by co-segregation of calcium (Ca) and silicon (Si) dopants. They found that the introduction of Ca ions led to a new grain boundary structure with larger free volumes and a chemically ordered structure formed by Si and Ca dopants. This research provides insights into grain boundary engineering using aliovalent co-segregation.

Summary: All-solid-state fluoride ion batteries are highly regarded for their high energy density and safety. However, the low F- ion conductivities of solid electrolytes at room temperature necessitate higher operating temperatures. KSbF4 doped with Rb has shown promise as a faster F- ion conductor. The ionic conductivity of K1-x Rb x SbF4 system strongly depends on the chemical composition, with maximum conductivity observed at x = 0.15. The F- ion conductivity in K0.85Rb0.15SbF4 was measured to be sigma (bulk) = 1.01 x 10(-4 )S cm(-1) and sigma (GB) = 4.80 x 10(-5 )S cm(-1) at room temperature.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
