Chevrel phase compounds have attracted increasing attention as electrochemical energy storage materials and electro-catalysts. Benefiting from their unique crystal structure, Chevrel phase compounds can not only function as the host structures for reversible intercalation of a broad range of cations, but also exhibit high catalytic activity in electrochemical reduction reactions. Here we provide an overview of recent progress in the development of Chevrel phase materials including new understanding of structural features, synthetic methods, and electrochemical properties. A brief conclusion and perspectives on the future development of Chevrel phase materials are also provided.

川藏铁路沿线存在着众多冰碛堰塞湖,且大部分位于高烈度地震区,堰塞湖溃决洪水成为对线路方案起控制作用的灾害类型,而地震涌浪是导致冰湖溃决的主要诱因之一。目前湖泊地震涌浪计算公式一般忽略湖盆的摩阻效应,对水深较浅且糙率大的冰碛堰塞湖而言,计算值偏小。鉴此,通过开展不同水深、不同地震峰值加速度、不同糙率的振动台造波模型实验,研究湖盆摩阻效应对地震涌浪的影响。根据实验结果,建立考虑摩阻效应的地震涌浪计算公式,并利用漫溢型溃决临界水文条件提出了冰湖溃决判据;最后以川藏铁路帕隆藏布流域为例进行应用说明,从而建立一种与选线原则方案确定阶段精度要求相匹配的冰碛堰塞湖地震涌浪溃决风险评估方法。本文公式考虑湖盆摩阻效应,适用于水深较浅的冰碛堰塞湖,尤其是在大震强震情况下,其计算结果偏安全。

As battery deployments in electric vehicles and energy storage systems grow, ensuring homogeneous performance across units is crucial. We propose a multi-derivative imaging fusion(MDIF) model, employing advanced imaging and machine learning to predict battery aging trajectories from minimal initial data, thus facilitating effective performance grouping before deployment. Utilizing a derivative strategy and Gramian Angular Difference Field for dimensional enhancement, the MDIF model uncovers subtle predictive features from discharge curve data after only ten cycles. The architecture includes a parallel convolutional neural network with lateral connections to enhance feature integration and *** on a self-developed dataset, the model achieves an average root-mean-square error of 0.047 Ah and an average mean absolute percentage error of 1.60%, demonstrating high precision and *** robustness is further validated through transfer learning on two publicly available datasets, adapting with minimal retraining. This approach significantly reduces the testing cycles required, lowering both time and costs associated with battery testing. By enabling precise battery behavior predictions with limited data, the MDIF model optimizes battery utilization and deployment strategies, enhancing system efficiency and sustainability.
