Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Vanadium oxides are deemed competitive cathode candidates for aqueous zinc‐ion batteries (AZIBs), benefited from their high theoretical capacity and multiple crystalline structures. However, the sluggish reaction kinetics, poor reversibility, and high solubility have hindered the practical application.

Gaoya dianqi, 2016 输电线路带电覆冰时,水滴会在接近导线表面过程中会引发局部电晕,而冰层会促使电晕放电更加明显,从而对电网的安全运行及其经济效益产生严重影响。目前国内外针对导线在涂污、淋雨等自然条件下的电晕放电特性进行了较为深入的研究,但针对覆冰过程中的电晕动态特性研究却尚未见报端。故文中在人工气候试验室对导线进行带电雾凇覆冰,利用Q-U法测得覆冰过程中的电晕放电量及放电功率的变化。试验结果表明:不同场强覆冰时的短时电晕放电量和放电功率不同,其大小随场强的增加而增加;覆冰时间的增加会使放电量及放电功率先增加后饱和 ...
