The charging dynamics of electric double layers (EDLs) have been extensively investigated through theoretical and simulation methods, yet the experimental studies remain limited. In this work, we accurately measure the charge dynamics between platinum plate electrodes and the aqueous solutions of seven electrolytes, including sulfuric acid, lithium sulfate, sodium sulfate, potassium sulfate, lithium nitrate, sodium nitrate, and potassium nitrate. This study explores the dependence of EDL charging dynamics on voltage, electrolyte concentration, and electrode distance with an equivalent circuit model employed in data analysis.

碱金属硫酸盐和硝酸盐水溶液中铂电极双电层充电动力学的测量

双电层（EDL）的充电动力学已经通过理论和模拟方法进行了广泛的研究，但实验研究仍然有限。在这项工作中，我们准确测量了铂板电极与七种电解质水溶液之间的电荷动力学，包括硫酸、硫酸锂、硫酸钠、硫酸钾、硝酸锂、硝酸钠和硝酸钾。本研究通过数据分析中采用的等效电路模型探讨了 EDL 充电动力学对电压、电解质浓度和电极距离的依赖性。
