Electrochemical Impedance Spectroscopy (EIS) measurements of Hybrid Supercapacitor

Hybrid Supercapacitors (HSC) are innovative energy storage solutions that are becoming essential in many fields of applications, like automotive, aerospace and consumer electronics. Their performances are strongly influenced by several parameters, such as temperature conditions, load characteristics and State-Of-Charge (SOC). For this reason, it is becoming fundamental to characterize their performances under different scenarios.<br>One of the best ways to investigate the performances is by employing the Electrochemical Impedance Spectroscopy (EIS) measurement. However, since HSC is a recent technology, databases and studies focused on impedance analysis are not currently available in the literature.<br>For this reason, this work presents the results of a large measurement campaign carried out to acquire impedance data on a large frequency range (from 1 mHz to 100 kHz) under 8 different operating temperatures and 6 different operating SOC conditions.<br>The constructed dataset has been used to investigate impedance anomalies and to analyze the effects that temperatures and SOC may have on the HSC impedance in the following paper: "M. Catelani, L. Ciani, F. Corti, M. Laschi, G. Patrizi, A. Reatti, D. Vangi, “Experimental characterization of Hybrid Supercapacitor under different operating conditions using EIS Measurements”, IEEE Trans. Instrum. Meas., vol. 72, 2023".<br>The obtained dataset can also be used for diagnostic and prognostic purposes, as well as for battery-supercapacitor comparison, SOC estimation, and safety zone identification.<br><br><b>If using this dataset in a publication, please kindly cite: </b><b>"M.

混合超级电容器（Hybrid Supercapacitors, HSC）是一类创新型储能解决方案，目前在汽车、航空航天、消费电子等诸多应用领域正成为不可或缺的核心技术。其性能受多种参数显著影响，包括温度条件、负载特性以及荷电状态（State-Of-Charge, SOC）。正因如此，在不同工况下表征其性能已愈发成为一项关键任务。

研究其性能的最优途径之一，是采用电化学阻抗谱（Electrochemical Impedance Spectroscopy, EIS）测量技术。然而由于HSC属于新兴技术，当前文献中尚未出现聚焦于其阻抗分析的专用数据库与相关研究成果。

为此，本工作呈现了一项大规模测量实验的结果：该实验在8种不同工作温度与6种不同工作SOC条件下，采集了覆盖1 mHz至100 kHz宽频率区间的阻抗数据。

所构建的数据集已被用于探究阻抗异常现象，并分析温度与SOC对HSC阻抗的影响，相关研究成果发表于论文："M. Catelani, L. Ciani, F. Corti, M. Laschi, G. Patrizi, A. Reatti, D. Vangi, “Experimental characterization of Hybrid Supercapacitor under different operating conditions using EIS Measurements”, IEEE Trans. Instrum. Meas., vol. 72, 2023".

该数据集还可应用于故障诊断与预后分析，以及电池-超级电容器对比、SOC估算与安全区间识别。
