Sepion Battery Cell Cycling Dataset

These files contain the Sepion Cell Dataset, consisting of 100 cells with raw and processed battery cell cycle data. The following describes the cells used, the testing, and each file and its contents: Cells Construction Cells are multi-layer pouch cells, 3 anodes / 2 cathodes Approximately 250-300mAh each All of the cathodes and anodes are from a single production campaign. Separators are from 3 lots. Cells are from a wider range of dates, provided in the data Bill of Materials: Cathode: NMC631 Anode: Graphite, 70:30 Artificial/Natural Electrolyte: LP57+FEC/VC Separator: 9 micron PE + 2 micron ceramic (single side) Purpose - Most of the cells derive from the same manufacturing process, with a small subset dedicated to electrolyte fill studies that may be used as a challenge problem. The file cell_metadata.csv describes the specific conditions for each cell. Testing Profile: 1C/1C, 30°C, over a consistent terminal voltage range Cycle Data: includes charge and discharge capacities, coulombic and energy efficiency Raw Data: Time, Current, Voltage File Structure Resources.zip - License, description of the dataset and cells, cell metadata register, and example files LICENSE dataset_description.md - overview of the dataset standard_cell_conditions.md - construction and processing conditions for cells cell_metadata.csv - details with one row for each cell CELLXXX_cycles.csv.stub - 100 lines of cycle data from a single cell for testing purposes CELLXXX_raw.csv.stub - 100 lines of raw data from a single cell for testing purposes Cycling.zip - cycling data, one file per cell, one row per cycle with summary information (charge and discharge capacity and energy, coulombic and energy efficiency) CELL[001-100]_cycles.csv Raw.zip - time, current, voltage CELL[001-100]_raw.csv
