Thermographic imaging of electrochemical double layer capacitors during cycling charging - discharging 0 - 2,7 V at 120 mA. Sample 103. Image period: 0,5 sec.

Dataset contains thermal images of prototype electrochemical double layer capacitor taken during cyclic charging - discharging. The sample was charged to 2,7 V and discharged to 10 mV by constant current 120 mA.  Sample 103. Thermographic pictures were taken relatively fast, with period of 0,5 sec in order to examine the fast fluctuations of sample temperature during cycling charging-discharging.The images were taken with thermographic camera VigoCAM V50. The sample was covered by black graphite paint to ensure uniform surface emission. For sample charging and discharging the ATLAS 1361 MPG&T was used.The sample is in a form of triplex envelope (6 cm x 7 cm) with active structure (2,5 cm x 4 cm) inside and electrodes contacts at one of envelope edge.The ASCII text data file consists of images acquired within a fixed period of measurement, T = 0,5 sec. The recorded image is a matrix containing 388 x 288 temperature data. Each image is preceded with header with image number, date and time of acquisition.

本数据集包含原型电化学双电层电容器（electrochemical double layer capacitor）在循环充放电过程中采集的热成像图像。本次测试样品编号为103，其充电截止电压为2.7 V，放电截止电压为10 mV，充放电过程采用120 mA的恒定电流。为捕捉循环充放电过程中样品温度的快速波动，热成像采集速率较快，单张图像的采集间隔为0.5秒。所有图像均通过VigoCAM V50型热成像相机采集。为保证样品表面热辐射均匀，测试前在其表面喷涂了黑色石墨涂料。样品的充放电测试由ATLAS 1361 MPG&T设备完成。该样品采用三层封装结构，封装尺寸为6 cm × 7 cm，内部活性区域尺寸为2.5 cm × 4 cm，电极触点位于封装边缘的一侧。配套的ASCII文本数据文件包含固定采集周期（T=0.5秒）内获取的图像数据。单张热成像图像为包含388×288个温度数据点的矩阵，每张图像前均带有包含图像编号、采集日期及采集时间的文件头。
