Summary: The magnesium driven reaction in the olivine-type MgMn0.5Zn0.5SiO4 structure is investigated through experimental tests and density functional theory (DFT) calculations. Partial replacement of Mn in Oh sites by Zn in the MgMn0.5Zn0.5SiO4 cathode is successfully achieved using a simple sol-gel method. Comparison with the well-known MgMnSiO4 olivine-type structure provides insights into the structure and magnesium extraction/insertion properties of the novel olivine-type (Mg)(M1)(Mn0.5Zn0.5)(M2)SiO4 composition. DFT calculations further extend the study to other divalent elements in the olivine-type (Mg)(M1)(Mn0.5M0.5)(M2)SiO4 structure with M = Fe, Ca, Mg, and Ni. The results suggest that the energy density can be tuned between 520 and 440 W h kg(-1) based on the atomic weight and redox chemistry properties, offering new possibilities for cathode material development in Mg batteries.

Summary: In the Mu''ller-Rochow process, copper is used as a catalyst for the reaction between CH3Cl and silicon. The interactions and decomposition of CH3Cl with different surfaces of copper were studied using density functional theory to understand the formation of coke in the process. CH3Cl weakly adsorbs on the surfaces and decomposes by breaking the C-Cl bond, leaving CH3 and Cl on the surface. Dehydrogenation of CH3 is a crucial step towards coke formation, as the presence of CH2 can lead to further reactions. Among the surfaces investigated, Cu(410) shows the lowest energy barriers for CH2 formation, indicating its thermodynamic favorability.

Summary: Hydrogen separation and purification are crucial for the widespread use of hydrogen energy. Lanthanum tungstate (LWO) based hydrogen permeable membranes have drawn attention due to their mechanical strength and chemical stability. However, the industrial application of LWO-based membranes has been challenging due to their modest hydrogen permeances. In this study, we present a novel graded porous supported symmetric (GPSS) LWO-based membrane with enhanced transport properties, gas exchange dynamics, and operational stability, significantly improving hydrogen flux compared to previous state-of-the-art membranes.

Summary: An effective symmetric structured dual phase mixed conducting oxygen separation membrane made of 60 wt% Ce0.9Gd0.1O2-delta - 40 wt% Ba0.5Sr0.5Co0.8Fe0.2O3-delta (60CGO-40BSCF) was prepared using aqueous tape casting. The membrane consisted of a dense thin layer in the middle and porous substrates on the two sides. This structure optimized both oxygen ion diffusion and surface gas exchange, resulting in increased oxygen permeation flux. Compared to a monotonous dense membrane, the porous supported symmetric membrane exhibited higher permeation fluxes. The study indicates that the porous supported symmetric membrane structure is an efficient strategy to enhance oxygen permeation flux.

Summary: In the Müller-Rochow process, copper is used as a catalyst for the reaction between CH3Cl and silicon to form methylchlorosilanes. The study investigated the mechanisms leading to coke formation by analyzing the interactions and decomposition of CH3Cl on different surface orientations of copper using density functional theory. It was found that CH3Cl adsorbs weakly on the surfaces and decomposes by splitting the C-Cl bond, resulting in CH3 and Cl on the surface. Dehydrogenation of CH3 is a critical step for coke formation, and the presence of CH2 can facilitate C-C bond coupling or further dehydrogenation. Among the surfaces studied, Cu(410) showed the lowest energy barriers for CH2 formation compared to gaseous CH3Cl, indicating its thermodynamic favorability.

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.
