Scope This collection contains records with structured data files representing GITT measurements on the positive electrode (cathode) harvested from an INR18650-MJ1 Li-ion battery cell. The active material in the electrode is NMC. The measurment is obtained in three-electrode configuration with the working electrode NMC, counter electrode composite graphite/silicon oxide, and reference electrode lithium metal in a coin cell casing. The records include raw data obtained from GITT and EIS measurements. The data is intended to be used to charactrize the open-circuit potential and lithium diffusion coefficient in the NMC material to support model-based analysis of MJ1 cells.
