Key facts
Contents & fields
The dataset contains impedance spectra and capacity measurements from periodic tests during life cycle tests of commercial 18650 (graphite/NMC) cells. Data are provided as files, with a PDF file offering detailed information. No field-level description is publicly available on the source page.
Research uses
Can be used to validate impedance-based residual capacity estimation models, supporting research on second-use of lithium-ion batteries.
This card was drafted from the source page; institution, coverage, time span, scale, fields and license are subject to the official page (pending human review).

Why this is hard to get on your own
Impedance data for batteries are often scattered and lack standardization; this dataset provides systematic life-cycle test data for model validation.
