Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Bismuth anode materials are considered promising anode candidates for sodium–ion batteries (SIBs) due to their high theoretical capacity and appropriate working potential. Nevertheless, the significant volume expansion that occurs during the cycling process restricts its broader application in sodium–ion storage. Herein, Bi/Bi2O3 nanoparticles

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...

Gaoya dianqi, 2019 高补偿度串补在远距离大容量特高压输电线路中有广阔的发展前景,但串补输电线路发生单相接地故障产生的潜供电流包含高幅值低频分量,不利于电弧快速熄弧。针对此问题,文中基于串补输电线路产生潜供电弧的机理,采用ATP-EMTP电磁暂态程序建立特高压串补系统仿真模型,并分别研究采用小电阻短接故障相串补以及联动旁路串补措施对潜供电流、恢复电压的抑制效果。结果表明,潜供电流的衰减速度与串补被短接或旁路的时刻有关,在断路器跳闸前将串补短接或旁路,可加快电弧熄弧速度 ...

Gaoya dianqi, 2020 随着电网规模扩大,短路电流超过开关遮断能力问题日益突出,目前常用的措施包括电网解环及分区运行、母线分裂运行、选用高阻抗设备等。但电网解环、分区、母线分裂运行削弱了电网供电可靠性,使输变电设备容量不能充分利用且可应用空间越来越小;高阻抗设备无法彻底解决短路电流问题还会降低系统稳定水平,增加网损。文中提出在短路电流超过开关遮断能力且无法通过更换开关或改变运行方式满足短路电流要求的变电站采用LCC-HVDC背靠背系统替代部分或全部交流变压器,既保证供电可靠性和供电能力又能有效抑制短路电流过大 ...
