Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

渗水对光缆寿命的影响

open access: yesGuangtongxin yanjiu, 2007
光缆的寿命是由光缆中所使用的材料寿命和光缆中光纤的寿命两方面来决定的。光缆长期使用过程中,难免要处于水汽环境中,水分对光缆材料寿命和光纤寿命均有影响。因此,光缆的渗水性能是评价光缆质量的重要指标之一,也是考核光缆环境性能的一个重要方面,是保证光缆寿命(2530年)的重要因素之一。文章探讨了水分对光缆寿命的影响以及如何采取有效措施降低这种影响。

Insights Into Ni2+‐Dominated Phase Regulation of Accordion‐Shaped CuNb2O6 Framework Toward Lithium‐Ion Capacitors

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT The monoclinic CuNb2O6 (M‐CNO) with a columbite structure is a potential anode candidate for advanced lithium‐ion capacitors (LICs). However, its practical application is plagued seriously by the irreversible phase transformation and sluggish kinetics.

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation

基于威布尔分布的油纸套管寿命预测模型

open access: yesGaoya dianqi, 2015
为研究油纸套管的寿命分布以及发生层间击穿后的剩余寿命,结合绝缘材料寿命的威布尔分布理论,建立了套管绝缘层寿命模型。并利用蒙特卡罗方法仿真计算了某型号110 k V油纸套管的寿命分布以及发生层间击穿后的剩余寿命分布。研究表明,该型号油纸套管的寿命符合形状参数为19.68,尺度参数为22.05的威布尔分布。当发生一层和两层击穿之后,形状参数分别减小为5.47和0.22,这意味着发生层间击穿之后由于电场分布的改变使得套管的寿命会迅速减小,层间击穿对于套管内绝缘是一个自加速过程 ...

Lithiophilic CoNiB Quantum Dots Embedded in N‐Doped Porous Carbon as Multifunctional Interlayer for Dendrite‐Free and Stable Lithium Metal Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Lithium metal batteries (LMBs) promise ultrahigh energy density, yet their advancement is impeded by dendritic lithium growth and unstable interfacial behavior. Herein, for the first time, we present novel lithiophilic CoNiB quantum dots embedded in nitrogen‐doped hollow carbon nanorods (CoNiB@NC) as a multifunctional interlayer on a ...
