Scope This record contains open-circuit voltage (OCV) data extracted from a GITT measurement on the harvested anode of the MJ1 cylindrical 18650 cell from LG CHEM. The active material of the harvested electrode is composite graphite/silicon oxide. The measurment is obtained in three-electrode configuration with the working electrode composite graphite/silicon oxide, counter electrode NMC, and reference electrode lithium metal in a coin cell casing. The data is intended to support the generation of parameterized OCV curves for use in battery cell modelling.
