title: INR18650-LG-3500-MJ1 Anode GITT Overpotential

description: Scope

This record contains overpotential observed in GITT measurements during discharge and charge, pre-selected and packaged in parquet files for further analysis.The GITT measurements were obtained from negative electrode (anode) harvested from an INR18650-MJ1 Li-ion battery cell manufactured by LG CHEM. The active material in the 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.
