Degradation path indicators for lithium-ion batteries

Short term aging study of a commercial lithium-ion battery

This dataset contains data from 48 commercial lithium-ion cells at beginning of life, during aging, and end of life. Information on the measurements performed can be taken in part from this readme file.  CCCV discharge capacity, pulse measurements in the charge and discharge direction, pseudo OCV measurements, EIS measurements, and NFRA measurements are recorded.  All measurements are performed in a BaSyTec Cell Test Systems (CTS-Lab) are used for cyclic aging and reference performance tests (RPT). Two climate chambers (Binder KB53 and CTS T-40/50) were used to control environmental conditions. EIS and NFRA measurements are performed using Zahner ZENNIUM Pro.

The data of each of the cells is uploaded as a zip file and each zip file has multiple files that represent different tests as described in the table below.

It should be noted that some EIS and NFRA might occur twice and they are appropriately numbered. The file extracted_degradation_metrics.xlsx contains information about the aging conditions for each of the cells tested in the study and degradation metrics extracted from the raw data.
