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

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.

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.

INR18650-LG-3500-MJ1 Anode EIS Data Preprocessing
This record contains workflows for packaging EIS measurements obtained during discharging and charging processes within parquet files. The workflows are intended to process EIS 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.
