Summary: Commercial use of solid oxide fuel cells (SOFCs) requires high output performance and excellent long-term stability. In this study, a nanostructured spinel high-entropy oxide (Fe0.2Mn0.2Co0.2Ni0.2Zn0.2)3O4 (FMCNZ) was developed as the SOFC cathode using an impregnation method. The FMCNZ cathode showed higher oxygen reduction reaction (ORR) performance compared to traditional spinel cathodes, attributed to the diversity of surface metal cations and the increase of surface oxygen vacancies brought on by the high entropy design. The nanostructured FMCNZ cathode exhibited stable performance after 100 hours of cell operation, providing a promising path for developing high-performance cathodes.

Summary: Development of active ceramic hydrogen electrodes with high stability is crucial for the advancement of solid oxide fuel cells (SOFC). In this study, a series of cubic perovskite-type La/Ca/Fe-doped strontium titanates (LSCTF) were synthesized and evaluated for their crystallographic and electrical properties, catalytic activity, stability, and performance as fuel electrodes in SOFC. The results showed that LSCTF materials behave like semiconductors, and the conductivity, catalytic activity, and stability of the electrodes are significantly influenced by the Ca concentration in the A-site. The optimal composition of La0.2Sr0.35Ca0.35Ti0.95Fe0.05O3-delta fuel electrode exhibited a low polarization resistance value and the fuel cell with a 50 wt % La0.2Sr0.35Ca0.35Ti0.95Fe0.05O3-delta + 50 wt % Ce0.9Gd0.1O2-delta anode demonstrated high power density.

Summary: Researchers have successfully demonstrated the topochemical deintercalation/reintercalation of sulfur in a layered oxychalcogenide, leading to the design of novel metastable phases. By reacting La2O2S2 with monovalent metals, they produced sulfur-deintercalated metastable phases La2O2S1.5 and oA-La2O2S, with lamellar structures predicted through an evolutionary structure-prediction algorithm. This study opens up new possibilities for the unexplored topochemistry of mobile chalcogen anions.

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.
