Scope
This record contains raw data from the GITT characterization of a negative electrode (anode) harvested from an INR18650-MJ1 Li-ion battery cell. The active material in the electrode is composite graphite/silicon oxide. 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 parameterization of open-circuit potential (OCP) and lithium diffusion coefficient in the composite material.

INR18650-LG-3500-MJ1 Anode Raw Data |
This collection contains records related to the characterization of 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 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 be used to charactrize the lithium diffusion coefficient in the composite graphite/silicon oxide material to support model-based analysis of MJ1 cells. |

INR18650-LG-3500-MJ1 Anode GITT Data Preprocessing |
This record contains workflows for packaging GITT measurements obtained during discharging and charging processes within parquet files. The workflows are intended to process GITT data coming from 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 resulting data can then be used for open-circuit potential (OCP) extraction. |
