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

description: 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.
