Summary: Protonic ceramic electrochemical cells (PCECs) have been attracting attention due to their ability to convert chemical fuels into electricity at low temperatures. However, conventional sintering conditions often result in nonstoichiometric electrolytes and electrode coarsening, leading to performance degradation. In this study, PCECs were fabricated through a microwave-assisted sintering process, which effectively suppressed undesirable diffusion and growth, thus producing PCECs with stoichiometric electrolytes and nanostructured fuel electrodes. The resulting PCECs demonstrated higher electrochemical performance compared to conventionally sintered PCECs, highlighting the effectiveness of the ultrafast sintering technique.

Summary: The development of materials with high intrinsic activity for oxygen activation and bulk proton conductivity is crucial in protonic ceramic fuel cells. However, a higher water content, while beneficial for increasing proton conductivity, can dilute oxygen and suppress oxygen adsorption on the electrode surface. To overcome this dilemma, a new electrode design concept is proposed, which involves introducing a second phase with high-hydrating capability into a conventional cobalt-free perovskite to form a unique nanocomposite electrode. This design enables high proton conductivity and concentration at low water content, and the hydronation also creates additional fast proton transport channels along the two-phase interface.

Summary: This study presents the performance and durability of protonic ceramic fuel cells (PCFCs) in an ammonia fuel injection environment. The use of a palladium (Pd) catalyst improves the low ammonia decomposition rate in PCFCs with lower operating temperatures. By treating the anode with Pd catalyst, the performance of PCFCs is significantly enhanced, with a peak power density of 340 mW cm (-2) at 500 degrees C. The Pd catalysts are deposited through an atomic layer deposition post-treatment process, improving current collection and reducing polarization resistance in the low-temperature region.

Summary: In this study, a facile strategy of anion engineering was proposed to improve the bifunctionality of layered LiCoO2 (LCO) for Zn-air batteries (ZABs). Partial substitution of fluorine for oxygen induced oxygen vacancies and modulated the electronic structure of Co, thereby accelerating oxygen electrocatalysis kinetics. The potential gap (Delta E) between the OER potential and ORR potential of LiCoO1.8F0.2 (LCOF0.2) catalyst (0.986 V) was significantly lower than that of pristine LCO catalyst (1.162 V), indicating a higher bifunctional activity. The ZABs using LCOF0.2 as the air electrode exhibited a peak power density of 193 mW cm-2, which was 1.53-fold higher than that of the LCO-based ZABs. This study demonstrates the feasibility of F doping to improve the bifunctional electrocatalytic performance of LiCoO2.

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.
