This dataset contains:

Data supporting the raw and fitted impedance data for the separators (Fig. 2) and electrodes (Fig. 4). 

The figures are as follows:

Fig. 2  Nyquist plots of the impedance measurements of cells with GF/F separators (a-c) and the Toray separators (d-f) filled with electrolytes of various concentrations. Three independent repeated experiments are shown for each cell.
Fig. 4  (a-c) Nyquist plots of electrolyte-filled carbon-sulfur composite electrodes in symmetrical cell configuration. The insets show a zoom-in of the plot for the OXIS electrodes; (d) equivalent circuit used to fit the data of the laboratory-scale produced electrodes; (e) equivalent circuit used to fit the data of the OXIS electrodes. 

Date of data collection: 01/10/16 to 04/05/18

Information about geographic location of data collection: University of Southampton, U.K.
