INR18650-LG-3500-MJ1 Anode EIS Raw Data

Scope This record contains raw data from the EIS 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 exchange-current density and lithium diffusion coefficient in the composite material.
