Datafile descriptions
----------------------

Electrodialysis_experimental_data.csv – collection of 23 electrodialysis tests using a synthetic Na2SO4-Li2SO4 feed, different operating conditions with the observed responses. The dataset includes solution volumes (ml), molar concentrations (M) of acid and base products, as well as elemental concentrations of the solutions (mg/kg solution).

Column A: Test run order.
Columns B-E: Operating conditions.
Columns F-H: Back-calculated feed composition by massbalancing the products.
Columns I-Q: Data for the electrode rinse solution.
Columns R-Z: Data for the salt feed solution.
Columns AA-AJ: Data for the acid product solution.
Columns AK-AT: Data for the alkali product solution.
----------------------

Black_mass_leaching_data.csv - collection of data from leaching of NMC 8111-type black mass.

Column A: Product name.
Column B: Mass of the product in grams (g).
Columns C-K: Elemental concentrations as milligram per kilogram solution (mg/kg).
----------------------

Solids_composition_experimental_data.csv - data for determnging the elemental composition of solid samples.

Column A: Sample name.
Column B: Mass of the sample in grams (g).
Column C: Solution volume upon dissolution of the sample in aqua regia an diluting it in ultrapure water.
Columns E-O: Elemental concentrations as milligram per kilogram solution (mg/kg).
Columns P-Y: Elemental composition of the solid samples as milligram per kilogram solid material (mg/kg), calculated from the elemental concentrations in columns E-O.
----------------------

Column A: Test identifier.
Column B: Date when the test was conducted.
Column C: Time stamp.
Column D: Measured current in amperes (A) at the time shown in column C.
Column E: Applied stack voltage in volts (V) at the time shown in column C.
----------------------

Thermogravimetric_analysis_experimental_data.csv - Thermogravimetric analys (TGA) of the nickel oxalate dihydrate (NiC2O4*2H2O) precipitate in nitrogen atmosphere.

Column A: Measured temperature in degrees Celsius (°C).
Column B: Time in minutes (min) during TGA when the temperatures in column A were measured.
Column C: Percental mass retained during TGA, as a fraction of the initial sample mass.
