Scope
This record contains an open-circuit voltage (OCV) model fitted to OCV curves from GITT measurements during discharging and charging. The GITT measurements were obtained from positive electrode (cathode) harvested from an INR18650-MJ1 Li-ion battery cell manufactured by LG CHEM. 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.
