Summary: This study evaluates the electrochemical performance of SCT10 cathodes in the presence of Cr impurities. The results demonstrate that Cr impurities lead to significant performance degradation, especially in wet conditions. Morphological damages and the formation of SrCrO4 and Co3O4 secondary phases on the cathode surface contribute to the deterioration of oxygen reduction kinetics and cathode activity. The study highlights the importance of surface Sr segregation in Cr deposition and emphasizes the need for attention in practical applications in solid oxide fuel cells.

Summary: In this study, the hydrogen generation performance of LPSO compounds and LPSO + Mg alloys in simulated seawater solution was investigated. Results showed that LPSO compounds, especially the single phase LPSO Mg(87.6N)i(5.5)Y(6.9), exhibited improved H2 generation features compared to pure Mg. Alloys containing both Mg and LPSO benefited from galvanic coupling between the two phases, leading to higher reactivity and lower activation energies.

Summary: This study successfully sintered Pr6O11, a recently developed promising oxygen electrode for Solid Oxide Cells (SOCs). Dense pellets or thin films were used to accurately measure the ionic transport properties via the isotopic oxygen exchange method. Dilatometry experiments and sintering tests with different thermal cycles resulted in overcoming phase changes and achieving a sintered relative density of 95% for Pr6O11. The ionic transport properties of Pr6O11 were determined through Isotopic Exchange Depth Profiling (IEDP) measurements in the temperature range of 400 < T degrees C < 800.

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: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

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.
