Summary: The promotional effect of mixed ceria-zirconia oxides (CZO) on the Mo/HZSM-5 catalyst for methane dehydroaromatization (MDA) reaction was studied. The surface and structural properties of the synthesized catalyst were thoroughly characterized, and the correlation between catalytic properties and MDA reaction performance was discussed. The impregnation of CZO solid solution on Mo/HZSM-5 improved the catalytic performance and benzene production rate, while reducing coke formation. The redox properties of CZO-deposited Mo/HZSM-5, acting as a selective oxygen supplier and performing hydrogen combustion, were identified as the main reasons for the enhanced catalytic activity.

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.

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.
