Summary: This article presents a conceptual design for a small-scale green ammonia plant, where ammonia synthesis is achieved by reacting hydrogen produced by a solid oxide electrolyzer with nitrogen purified from air using a series of solid electrolyte oxygen pumps. The system operates with an energetic efficiency of 52.12%, which is very close to a cryogenic ASU reference system achieving an efficiency of 52.89%. The specific energy consumption is 9.94 kWh/kgNH3. Although these results are promising, there are opportunities to further improve the system design, such as enhancing heat integration to utilize waste heat from the series of oxygen pumps for raising the steam required by the electrolyzer.

Summary: Developing oxygen electrodes with improved polarization is crucial for enhancing the commercial viability of solid oxide electrolyzers. SrTi0.3Fe0.7O3-delta (STF) has shown to be an active and stable oxygen electrode, and its performance can be enhanced by Sr deficiency. However, the mechanism of how Sr deficiency affects the polarization behavior of STF remains unclear. This study investigates the electrochemical characteristics of Sr1-xTi0.3Fe0.7O3-delta (STFx; x = 0.03 and 0.06) to understand the impact of Sr deficiency on electrode polarization. The results demonstrate that Sr deficiency effectively improves the electrode/electrolyte interfacial resistance and oxygen-transport kinetics.

Summary: In this study, an innovative La0.6Sr0.4CoO3 (LSC) nanostructured air electrode with superior catalytic activity and exceptional robustness against delamination-induced degradation at the interface is reported. The LSC air electrode, decorated onto a porosity graded Gd0.1Ce0.9O2 backbone through ultrasonic-assisted infiltration, demonstrated significantly improved oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) kinetics, leading to prolific electrochemical performance compared to conventional LSC air electrodes. The fuel cell mode achieved a maximum power density of 2.24 W cm(-2), while the electrolysis mode achieved a maximum current density of 4.57 A cm(-2) at an operating voltage of 1.6 V at 750 degrees C. Remarkable durability was observed through reversible cycling and galvanostatic stability tests, attributed to the elimination of detrimental O-2 pressure at the air electrode/electrolyte interface. This study presents a highly durable SOC design for the production of green hydrogen and electricity, showcasing one of the highest performance levels to date.

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: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

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.
