Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Prelithiation is effective for compensating active lithium‐ion (Li+) loss in silicon (Si)‐based battery electrode materials. However, owing to the dynamic growth of the solid electrolyte interface (SEI), capacity fading remains the biggest challenge for the industrialization of Si electrodes.

Gaoya dianqi, 2012 弓网良好接触是保障机车稳定受流的关键,合适的弓网接触压力是弓网稳定可靠受流的基础。笔者研究了不同接触压力、牵引电流条件下的弓网静态接触电阻,并得到了弓网接触电阻的数学表达式。研究结果表明:弓网静态时接触电阻随接触压力、牵引电流增大而减小,接触压力小于7080 N,接触电阻所接触压力的增加,接触电阻激剧减少;大于7080 N后,接触电阻随接触压力的变化不明显,近似恒定关系。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...

Gaoya dianqi, 2018 SF6高压断路器触头间的动态接触电阻是反映SF6高压断路器弧触头烧蚀程度的一个重要参数。研究弧触头动态接触电阻与弧触头的烧蚀程度之间的关系具有重要意义。基于电接触理论,建立了一个弧触头动态接触电阻仿真的理论模型。通过开断过程中的弧触头受力情况分析,得出在八触指自力型弧触头模型中,电流小于2 k A时,可忽略各种电动力的影响,只考虑触指接触压力的影响。在这个假设下,文中首次建立了简化的弧触头动态接触电阻的仿真模型。与大量弧触头模拟烧蚀试验结果对比,文中所提出的弧触头动态接触电阻仿真模型 ...

Gaoya dianqi, 2015 为了准确测量并评估GIS导电连接件的电接触状态,针对基于超级电容器产生的千安级冲击电流测量导电连接件回路电阻的测试方法,提出依据回路电阻随测试电流增长的变化率大小来判断GIS触头电接触状态是否良好的评估判据。利用该方法对多种典型标准的GIS导电杆进行多触头串联验证试验以及GIS变电站现场验证试验。试验结果表明,基于千安级冲击电流的GIS电接触状态的评估方法具有可行性和有效性,比传统直流压降法更能反应导电连接件触头的电接触特性。
