Dataset for following 8 batteries' SoH decline: Including charge-discharge curves, ICI and EIS data

8 Aspilsan INR18650 batteries with NMC 622 cathode and graphite anode were subjected to number of tests. Mainly the State of Health (SoH) was tracked to correlate with Electrochemical Impedance Spectroscopy (EIS) and/or Intermittent Current Interruption (ICI) tests. These tests were applied in 50 charge-discarge cycle intervals for 1150 cycles. The data package includes all files for tests and cycling and a thorough, descriptive text file for all data.本次研究选取8颗搭载镍钴锰622（NMC 622）正极与石墨负极的Aspilsan INR18650型锂离子电池，开展多组测试。本次测试的核心为追踪电池健康状态（State of Health，简称SoH），并将其与电化学阻抗谱（Electrochemical Impedance Spectroscopy，简称EIS）及/或间歇电流中断（Intermittent Current Interruption，简称ICI）测试的结果进行关联分析。上述测试每间隔50个充放电循环开展一次，整个测试周期共计1150个充放电循环。本数据包涵盖了所有测试与循环测试的相关文件，以及一份针对全部数据的详尽描述性文本文件。
