Summary: The impact of electric field/current on creep deformation in fine-grained 8 mol% Y2O3 stabilized cubic ZrO2 was investigated under direct and alternative current conditions. The acceleration effect caused by electric fields/currents, which cannot be explained by the increase in sample temperature due to Joule heating, is more significant in AC than in DC conditions. The deformation mechanism changes from diffusional creep to grain boundary sliding (GBS) under DC and AC, indicating that the athermal effect of electric field/current enhances GBS and its rate controlling process of cation diffusivity, especially in AC.

Summary: In this study, yttrium-stabilized zirconia (YSZ) with different yttrium (Y) content was co-deposited with Ni-P coatings using electroless plating. The effects of YSZ doping on the microstructure, phase structure, element valence, corrosion resistance, and wear resistance of the coatings were investigated. The results show that the increase in Y content in YSZ leads to enrichment of metal oxidation states on the coating surface. The presence of YSZ also enhances the crystalline diffraction and improves the corrosion resistance and wear resistance of the coatings.

Summary: The YSZ ceramics doped with Eu3+ ions were successfully fabricated by SPS technique. The increase of europium concentration did not significantly affect the transmission spectra, while annealing process at different temperatures had a significant impact on it due to the formation of oxygen vacancy defects.

Summary: The influence of rare earth oxides on the properties of zirconia crystals was investigated in this study. It was found that an increase in the concentration of stabilizing oxides leads to a decrease in crack resistance and conductivity of the crystals, as well as changes in the defectiveness of the crystal structure. Additionally, the ionic radius of trivalent cations was found to impact the crack resistance and high-temperature conductivity of the crystals. Furthermore, it was discovered that ZrO2 solid solutions stabilized with Sm2O3 can be used as functional supporting membranes in solid oxide fuel cells.

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: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

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.
