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

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 Files Data Filename Description Format Usage 18650-LG-3500-MJ1-anode-GITT-EIS-Ch.parquet Parquet file containing GITT charge data for the MJ1 anode with intermittent EIS.
