Summary: This study reports a Ru-promoted perovskite-type cathode for the electrochemical reduction of CO2, which effectively improves the low current density, low Faradaic efficiency, and high overpotential of the CO2 reduction reaction. The Ru-doped cathode significantly enhances the CO2 reduction current density and reduces the electrode polarization resistance, leading to improved stability of the solid oxide CO2 electrolyzer. Relaxation time distribution analysis indicates that Ru doping activates the rate-determining processes of CO2 adsorption, dissociation, and activation.

Summary: This study demonstrates that the novel electrochemical catalyst improves the stability and electrochemical performance of R-PCCs. The enhanced stability and performance of the air electrode catalyst may be attributed to the higher electronegativity of La, which reduces basicity and improves chemical stability in acidic atmospheres; the smaller ionic radius of La, which alleviates lattice distortion; and the stronger interaction between La and lattice oxygen, inhibiting structural degradation caused by Sr segregation.

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.
