真空断路器的机械寿命,在很大程度上取决于真空灭弧室的机械寿命。而真空灭弧室的机械寿命,又与波纹管的寿命有很大关系。据统计,因波纹管漏气导致真空灭弧室损坏者,占真空灭弧室机械损坏的大多数。因此,对波纹管的研究,就成了真空灭弧室机械寿命研究的重要环节 ...

ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

ABSTRACT Sodium metal batteries hold significant promise for large‐scale energy storage due to the high theoretical capacity and abundant sodium sources, yet sodium‐metal anodes are hindered by dendrite propagation, unstable solid electrolyte interphase, and poor cycling efficiency arising from uneven Na deposition and volume changes.

ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle

ABSTRACT Size‐controllable Sn nanoparticles are designed in this work via oxide doping to be uniformly embedded into flexible N‐doped carbon nanofibers, in which the agglomeration and migration of Sn are effectively restrained due to the suppressive effect of selected oxides, including SiO2, TiO2, and ZnO. Benefiting from unique merits of the embedment

Lithium Deposition Behavior of Reconstituted Two‐Dimensional Zeolite Y Separators
ABSTRACT During the operation of lithium‐ion batteries, uncontrollable lithium dendrite growth often occurs, resulting in internal short circuits and a significant reduction in cycle life, which poses a major obstacle to their practical application.
