Rare Metals, EarlyView.ABSTRACT Nb‐Si‐based superalloys are considered as the most potential candidate materials for nickel‐based superalloys due to the lower density and higher using temperature. Here, a type of stable Nbss/γNb5Si3 bi‐phases structure with a coherent interface has been successfully designed. Additionally, the Nbss and γNb5Si3 phases showcase the orientation

Rare Metals, EarlyView.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

基于动态可重构电池网络的大规模退役动力电池梯次利用储能系统运行性能评估 [PDF]
全球能源互联网退役动力电池因其一致性差、安全性薄弱等缺陷在梯次利用时面临巨大挑战。动态可重构电池网络（dynamic reconfigurable battery network，DRBN）能够有效提高退役动力电池梯次利用储能系统的一致性和安全性。目前DRBN储能系统已经进入工程应用阶段，然而现有的研究缺少对大规模DRBN储能系统的运行性能评估。为此，以实际运行的大规模退役动力电池梯次利用储能系统作为分析对象，选取储能系统中80个DRBN的1个月运行数据进行分析。从运行工况、均衡效果 ...
