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

description: Scope

This record contains GITT measurements with intermittent 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 open-circuit potential (OCP) and lithium diffusion proprties of the graphite/silicon oxide active material. Note that the GITT signal floats during EIS measurements.

Legend for the dataset column names:



"LINE": # of the step in the measurement device script

"COMM": type of the step (Charge/Discharge/...); intermittent EIS measurements happen during "Set-Temp", since the measurement device links with the climate chamber

"STATE": labels start (3) and end (2) of any step

INR18650-LG-3500-MJ1 Anode GITT+EIS Raw Data
This record contains raw data from the GITT characterization with intermittent EIS measurements 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.
