Description
Scope
This record contains EIS 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 exchange-current density and lithium diffusion proprties of the graphite/silicon oxide active material.

| isPartOf | INR18650-LG-3500-MJ1 Anode Structured Data | This collection contains records with structured data files representing GITT measurements on the negative electrode (anode) harvested from an INR18650-MJ1 Li-ion battery cell. 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. 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 composite graphite/silicon oxide material to support model-based analysis of MJ1 cells. |
