Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

Gaoya dianqi, 1992 通过对国产10kV/630A/20kA真空断路器实际电寿命试验以及大电流开断试验,研究了大功率纵磁场真空断路器采用大电流加速电寿命试验方法的可行性,试验及理论分析表明,对于纵磁场真空断路器采用大电流加速电寿命试验不仅方法可行,而且还能由短路电流分断次数推算出等效额定电流下的操作次数来。

Gaoya dianqi, 2023 目前针对交流GIS聚酰亚胺电极覆膜微粒抑制效果及绝缘寿命评估的相关研究尚不清晰。文中针对交流GIS，首先基于金属微粒荷电机理与受力模型，搭建了电极覆膜金属微粒运动观测平台，通过观测聚酰亚胺电极覆膜的微粒抑制效果，验证了电极覆膜对微粒抑制的有效性。具体结果表明，薄膜厚度与微粒抑制效果呈正相关特性，不同厚度的聚酰亚胺薄膜对金属微粒启举电压的增幅在49%～68%。其次建立了聚酰亚胺薄膜表面放电特性与寿命测试系统，测试不同厚度实验样品的放电统计参量，明确其放电特性，进而测试不同厚度聚酰亚胺薄膜的绝缘寿命 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...

Gaoya dianqi, 2008 为了研究电容器的寿命与其工作可靠性的关系,笔者通过对脉冲电容器进行充放电老化试验,并对处于不同寿命阶段的电容器进行直流局部放电测试,得到最大放电量、平均放电量和平均放电重复率随寿命变化的曲线;借助电子显微镜观察处在不同老化寿命阶段电容器薄膜的表面微观形貌,分析充放电老化试验对其微观形貌的影响。最后结合电容器实际击穿情况,分析总结了导致脉冲电容器局部放电性能变化以及老化击穿的因素,指出电极边缘区域存在的局部绝缘缺陷是电容器失效的主要原因。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Gaoya dianqi, 1992 现代的SF6断路器制造技术,不仅能把断路器的开断能力做得很高、而且电寿命也很长,在额定电流下可达到几千次,额定短路电流下也能做到几十次,因此不检修周期可达10～20年。要保证这么高的电寿命必须有更高的机械寿命才有可能。因此,研究提高断路器的机械寿命,是生产厂家的重要课题之一。 我厂和西安高压电器研究所等兄弟单位联合研制的LW8—35/1600 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The poor Zn chemistry of Zn metal anode and sluggish reaction kinetics of cathodes at high mass loadings are two crucial issues for hindering the application of aqueous Zn‐ion batteries (AZIBs). Herein, the hierarchical porous N‐doped carbon fibers (HPNCFs) were proposed to simultaneously optimize the reversibility of Zn plating/stripping of ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−
