title: INR18650-LG-3500-MJ1 Anode GITT Structured Data

description: Scope

This record contains GITT measurements during discharge and charge, pre-selected and packaged in parquet files for further analysis. The measurement 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 characterization of the open-circuit potential (OCP) and lithium diffusion proprties of the graphite/silicon oxide active material.
