Summary: Perovskite-type Sr11Mo4O23 material undergoes a phase transition around 400 degrees C, resulting in a drop in conductivity. In this study, a novel Sr10.8A0.2Mo3.5Ta0.5O23-delta electrolyte is synthesized with doping of Ta and alkali metals (Li, Na, K). The doping inhibits the phase transition and enhances the electrical conductivity of Sr11Mo4O23. Among the samples, Sr10.8K0.2Mo3.5Ta0.5O23-delta shows the highest conductivity and exhibits good stability under different atmospheres. Single cells with Sr10.8K0.2Mo3.5Ta0.5O23-delta electrolyte show improved power density compared to cells with Sr11Mo4O23 electrolyte, suggesting its potential for IT-SOFCs.

Summary: A series of Ce-doped coatings (Mn1.5-xCo1.5-xCe2xO4+delta, x = 0, 0.025, 0.05, and 0.1) were prepared to improve the electrical conductivity of solid oxide fuel cell (SOFC) interconnect coatings. Experimental results showed that Ce doping effectively reduced the area-specific resistance of the coatings. However, excessive Ce doping led to more structural defects and weakened the oxidation resistance of the coatings.

Summary: This study investigates the application of copper-doped Pr0.6Sr0.4Fe0.8Cu0.1W0.1O3-delta (PSFCuW) as a symmetric electrode material in La0.8Sr0.2Ga0.8Mg0.2O3-delta (LSGM)-based symmetric solid oxide fuel cells (SSOFCs). The research analyzes the effect of Cu-doping on the stability and mechanism of the hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR). The results show that partial substitution of Fe with Cu can maintain the phase structure stability and improve the electrical conductivity. The rate-limiting steps under oxidation conditions are oxygen adsorption and diffusion, while under reducing atmospheres, hydrogen adsorption and charge transfer have significant influences on the rate-limiting step. The LSGM-supported SSOFC (PSFCuW|LSGM|PSFCuW) demonstrates excellent stability and reversibility.

Summary: Solid oxide fuel cells, being highly efficient and environmentally friendly, face limitations due to their high operating temperatures. This study focuses on reducing the temperatures by using proton conductors as the electrolyte, specifically yttrium-doped barium cerate with high conductivity. Through solid-state reaction, dense pellets of BaCe0.9Y0.1O3-delta were successfully obtained at a low sintering temperature of 1200 oC without sintering aid, enabling co-sintering with other cell components. The study also highlights the role of intrinsic liquid phase in the microstructural development and its effect on promoting densification and specific grain boundary conductivities at low temperatures.

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: A new type of Ruddlesden-Popper Pr1.2Sr0.8Ni1-xMoxO4+delta (PSNMO) cathode with different Mo doping levels was prepared using the sol-gel method. The maximum conductivity of Pr1.2Sr0.8NiO4+delta cathodes was achieved and then decreased with the continuous increase of Mo amount in all the Mo-doped cathodes. The Pr1.2Sr0.8Ni0.950Mo0.050O4+delta cathode showed the lowest polarization resistance among the PSNMO cathodes at 750 degrees C. Mo-doping improved the oxygen surface exchange properties of PSNMO cathodes, mainly due to the co-interaction of oxygen vacancy and interstitial oxygen in PSNO cathodes after Mo-doping.

Summary: The perovskite/Ruddlesden-Popper oxide heterostructure (Nd,Sr)CoO3 (NSC113)/(Nd,Sr)2CoO4 (NSC214) has been found to significantly enhance the oxygen reduction reaction (ORR) activity due to two main factors: enhanced oxygen adsorption and accelerated transport of interstitial oxygen. Additionally, the perovskite/double-layered R-P oxide heterostructure is predicted to exhibit better ORR performance compared to the perovskite/single-layered R-P oxide heterostructure. This work provides important insights into the atomic-level mechanism of ORR enhancement on perovskite/R-P oxide heterostructures, which is highly significant for the development of high-performance electrochemical devices.

Summary: Due to high ion conductivity, low cost, and adjustable composition, antiperovskite has attracted attention in solid-state batteries. Ruddlesden-Popper (R-P) antiperovskite is more stable and enhances conductivity. However, systematic theoretical research on R-P antiperovskite is scarce. This study calculates the transport performance, thermodynamic properties, and mechanical properties of R-P antiperovskite LiBr(Li2OHBr)(2) and compares it with H-free LiBr(Li3OBr)(2). Results show that LiBr(Li2OHBr)(2) is prone to defects and increasing LiBr Schottky defects can improve its Li-ion conductivity. The research provides insights into the practical application of R-P antiperovskite in solid-state batteries.

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.
