Dianci bileiqi, 1994 阐述了直接法、间接法和湿法（活性氧化锌）三种方法生产的氧化性原料的特点，并分别用此三种原料进行了压敏电阻验证试验。结果表明，间接法生产的氧化锌原料用作压敏电阻性能最好，湿法生产的氧化锌原料也可用作压敏电阻原料，而直接法生产的氧化锌原料则不能直接用于压敏电阻原料。考虑到价格性能比及原料的二次加工，湿法生产的氧化锌原料有望得到应用和推广。

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

Dianci bileiqi, 2017 在对氧化锌压敏电阻的劣化研究中,由于U1mA和Ileakage存在"拐点效应",从而不能够第一时间判断出氧化锌压敏电阻劣化的情况。为此通过实际的冲击平台,研究在不同冲击时间下,氧化锌压敏电阻阀片内部的温度变化情况,主要得出:距离电极较近位置处的变温率较大,远离电极的一端变温率较小,即氧化锌压敏电阻存在极性现象;当变温率出现明显的变化时,压敏电压U1mA和漏电流Ileakage变化处于正常范围内,当压敏电压U1mA和漏电流Ileakage出现明显变化时,氧化锌压敏电阻已经劣化到一定程度,甚至已经完全损坏 ...

Dianci bileiqi, 2018 带间隙氧化锌避雷器已广泛应用于输电线路。由于其正常运行时无泄漏电流,目前尚无有效的带电检测手段判断其性能劣化状况。本文通过35 kV氧化锌避雷器的雷电冲击试验,研究了氧化锌阀片老化与雷电冲击的幅值及大电流冲击的次数间的定量关系;以及大电流冲击时避雷器本体温升与其劣化程度的关系;提出了以氧化锌避雷器大电流冲击次数及本体表面温升作为状态量的带间隙氧化锌避雷器状态监测方法,研发了相应的间隙氧化锌避雷器在线监测装置。实验室测试结果表明该方法的有效性。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...
