Gongye shui chuli, 2002 测定了不同材料电极的i-V关系曲线,研究了电解过程中溶液电导率、电极板间距以及电极联结方式对i-V关系的影响。实验表明,在槽电压V相同时,铁电极的电流密度大于石墨电极,远大于铝电极。在相同电流密度i下,高溶液电导率对应的槽电压较低,而且随着i的增加,不同溶液电导率下的槽电压差别增大。在槽电压V相同时,随着电极板间距的增加,电流密度逐渐减小。不同电极板间距下铁电极的i -V曲线均呈现良好的线性关系。铁电极的电压梯度与电极板间距之间存在很好的线性关系。对应于相同的电流密度 ...

Dianci bileiqi, 2020 为了明确接地装置冲击试验时回流极布置对冲击特性测试的影响,研究了回流路径对实际塔脚冲击特性的影响。测试了塔基的四种不同回流电极结构:单根电极、多根电极、环形电极、环形电极和多根电极的组合电极的冲击响应,同时与常用的单回路电极测试的结果进行了比较。研究表明:在不同的回流极结构下,测量得到不同的冲击接地电阻值和地电位升,相比单根回流极,多根回流极和环形回流极的组合可更好的地模拟雷电真实放电情况。

Gongye shui chuli, 2012 增大电极比表面积是提高电容去离子效率的方法之一．通过研究活性炭负载量对电极比表面积的影响，探讨了一种提升炭电极电容去离子性能的有效方法．实验结果表明，增加活性炭负载量可有效提升电极比表面积，电极电容最高可达0.56 F/cm2，表现出较好的电容去离子性能．持续增加活性物质虽对电极内电阻影响较小，但不能进一步提高电极吸附表面，比电容急剧下降．优化电极孔隙结构是提升活性炭电极电吸附性能的有效方法．

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tin‐based composite oxides typically undergo severe volume variations and exhibit poor intrinsic conductivities despite their high theoretical capacity as promising anode candidates for sodium‐ion batteries. This results in rapid structural degradation and capacity fading upon cycling.
