Supporting information: Understanding the stability of the solid electrolyte interphase formed by vinylene carbonate and fluoroethylene carbonate in sodium-ion batteries

This deposit has the experimental data supporting the article:Understanding the stability of the solid electrolyte interphase formed by vinylene carbonate and fluoroethylene carbonate in sodium-ion batteries.Jan Felix Schuster*, Qihan Hu, Laura King, Alexandre Linas Lapidus, Charles Aram Hall, Leif Nyholm and Reza Younesi*DOI: 10.1039/d6fd00038j Published in Faraday Discussions. Department of Chemistry - Ångström Laboratory, Uppsala University, 75121 Uppsala, Sweden. *[e-mail] *[e-mail] The electrochemical data is provided as combined CSV files for each figure. The cell_metadata gives information about what each cell_id stands for. There are additional columns found in the CSV file that have been computed; these are "current_density_mA_cm2" and "voltage_vs_Na_V". Current density is computed based on the area of the working electrode, and the voltage is calculated based on the reference potential, which is assumed to be 3.3V vs Na/Na+. Electrochemical data were collected on biologic equipment, and the data were transferred to parquet files to be plotted. Codes for how the figures were generated and the data parser can be provided if required. XPS data is provided after it has been normalised and calibrated. Raw data can be provided if required. GC-MS data is only shown as the chromatograms; raw data can be provided on request.
