The electrochemical ammonia oxidation reaction (AOR) is a pivotal process for harnessing ammonia as a sustainable energy source, enabling hydrogen production through ammonia decomposition or electricity generation via direct ammonia fuel cells. NiCu, a transition metal alloy, has shown great potential as an efficient and cost-effective catalyst for AOR. In this study, high-valence Ni and Cu hydroxyl hydroxides were synthesized on nickel foam to form NiCuOOH in the structure of folded nanosheets, serving as an anodic electrocatalyst for AOR. Comprehensive characterization identified high-valence metals as the primary active components. By optimizing the Ni/Cu ratio, the catalyst achieved remarkable performance and stability, reaching a maximum current density of 169 mA cm−2 at 1.62 V versus RHE, with 0.16 at% Cu delivering high ammonia oxidation activity, and being stable for 48 h at 100 mA cm−2. Additionally, the catalyst exhibited excellent catalytic activity for the oxygen evolution reaction (OER), attaining a maximum current density of 152 mA cm−2 at 1.72 V versus RHE.

In this study, the aging behavior and thermal safety of LIBs at different overdischarge cut-off voltages are investigated. The results show that overdischarge significantly affects the discharge ability of the battery, with a capacity decay rate of 38.2% at an overdischarge cut-off voltage is 0.5 V. Electrochemical test results indicate that overdischarge accelerates the loss of the active materials and the increase of impedance. Quantitative analysis shows that the conductive loss and lithium inventory loss are the main causes of battery aging. The disassembly images and further physicochemical characterization indicate that with the decrease of overdischarge voltage, the dissolution of copper current collector and the increase of electrode surface attachments intensify. The differential scanning calorimetry test indicates that the thermal stability of the anode is reduced. These aging behaviors lead to the loss of active materials, the damage of the electrode structure, and the increase of gas production inside the overdischarge batteries, which results in the advance of the thermal runaway time, the decrease of the thermal runaway onset temperature and the thermal runaway peak temperature.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crystals with unique properties such as low-dimensional materials, metal-organic frameworks, and defected crystals, in particular, exhibit different structures from bulk crystals and possess exotic physical properties, making them intriguing subjects for investigation. To accurately predict the physical and chemical properties of crystals, it is crucial to consider long-range orders. While GNNs excel at capturing the local environment of atoms in crystals, they often face challenges in effectively capturing longe range interactions due to their limited depth. In this paper, we propose CrysToGraph (Crystals with Transformers on Graph), a transformer-based geometric graph network designed for unconventional crystalline systems, and UnconvBench, a benchmark to evaluate models' predictive performance on multiple categories of crystal materials. CrysToGraph effectively captures short-range interactions with transformer-based graph convolution blocks as well as long-range interactions with graph-wise transformer blocks. CrysToGraph proves its effectiveness in modelling all types of crystal materials in multiple tasks, and moreover, it outperforms most existing methods, achieving new state-of-the-art results on two benchmarks.

One potential solution to address this issue is the implementation of a circular economy model. This study aims to identify and assess the key barriers to optimizing a sustainable supply chain in the lithium-ion battery circular economy using an integrated Gray Multi-Criteria Decision Making approach within the automotive sector. The novelty of this research lies in its application of Gray Possibility Comparison and Gray Possibility of degree to address these uncertainties. By integrating Gray DEMATEL (Decision Making Trial and Evaluation Laboratory) and Gray ANP (Analytic Network Process) methods, this study offers a more flexible and adaptive framework for identifying and analyzing the interrelationships among barriers. The research process involves validating the identified barriers through the Gray Delphi method, followed by the application of Gray DEMATEL to establish the cause-effect relationships among the barriers. Finally, Gray ANP is used to assign weights and prioritize the barriers into primary and secondary categories.
