Summary: With the increasing demand for lithium-ion batteries (LIBs), there is a need for high-energy-density batteries, which can be achieved through the use of lithium metal as a higher-capacity anode. However, due to the low efficiency and safety concerns of lithium metal, anode-free lithium-metal batteries (AFLMBs) have gained attention. The reversibility of lithium-metal plating/stripping is a crucial parameter for improving the performance of AFLMBs.

Summary: In this study, shot peening is used to improve the interface resistance and critical current density of an all-solid-state lithium metal battery with oxide solid electrolyte. The results show that shot peening significantly reduces the interface resistance and increases the critical current density. Additionally, a synergistic effect is observed when shot peening is combined with gold thin-film insertion. Measurements suggest that the improvement in electrode performance is a result of increased contact between the solid electrolyte and lithium metal, as well as the suppression of lithium dendrite growth through the application of compressive residual stress.

Summary: Solid-electrolyte interphases (SEIs) in advanced rechargeable batteries can mimic the chemistry and structure of cell membranes, allowing for selective ion transport and regulating electrode reactions. Researchers have reported SEIs that exhibit thermally activated selective ion transport, functioning as open/close gate switches. This ion gating is achieved through Arrhenius-activated ion transport and SEI dissolution/regrowth. The understanding of this biomimetic property of SEIs can guide the design of better SEIs for future battery chemistries.

Summary: Before the practical application of Li-O2 battery, the issue of large overpotential upon charging needs to be addressed. The utilization of redox mediators is a promising solution to decompose the insulating discharge product, Li2O2. However, soluble redox mediators can easily react with the Li metal anode. This study introduces a chemical self-assembly strategy to fabricate a Li-ion-philic membrane with an electronegative d-MnO2 layer, which repels iodide species and regulates uniform Li+ deposition. The resulting LOB demonstrates low overpotentials, dendrite suppression, and impressive long-term reversibility.

Summary: This study proposes a simple, scalable, and inexpensive electrode engineering and recycling strategy for rechargeable zinc-air batteries (ZABs) based on magnetic binder engineering of cobalt-implanted electrocatalysts. By manipulating the electrode with magnets, the ZAB can cycle for 1200 hours, and its anti-pulverization behavior is revealed through in situ observation. The cobalt-implanted electrocatalysts can also be recycled from spent ZABs using a magnetic force-separation method, and the recycled electrocatalysts exhibit considerably prolonged cycling stability for over 500 hours. These findings not only enhance battery performance but also provide sustainable solutions for recycling electrocatalysts for various applications beyond ZABs.

Summary: Despite the low proton conductivity of most cathode materials in proton ceramic fuel cells (PCFCs), a composite cathode material consisting of La5.5W0.45-Mo0.4Nb0.15O11.25-delta (LWMN) and Sr2Sc0.1Nb0.1Co1.5Fe0.3O6-delta (SSNCF) was developed to enhance proton diffusion and weaken CO2 adsorption. The symmetrical cell based on the 3 wt% LWMN-SSNCF cathode achieved a lower linear degradation rate of ASRs compared to the single-phase SSNCF cathode. Furthermore, the PCFC with the composite cathode exhibited improved performance due to its superior proton conduction.

Summary: Although the bulk properties of catalytic materials can be easily regulated by doping, their surface where electrocatalysis occurs is often hard to be controlled. In this work, a surface tailoring strategy is proposed to finely manipulate the surface cation configuration of a Ruddlesden-Popper perovskite La2NiO4. By removing surface-enriched inactive La element and forming active Ni-Fe pairs, the surface tailored catalyst exhibits exceptional water oxidation performance. The study demonstrates that a dynamically reconstructed thin-layer surface with an equal amount of Ni and Fe elements, combined with a steady La-terminated subsurface, is the key to achieving high OER activity and durability.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
