Comprehensive parameter set and electrochemical data for a 1 Ah graphite/LNMO battery cell for physical modelling

Scope: This dataset contains electrochemical measurements for a graphite-LNMO 1 Ah prototype pouch cell that was developed and characterized within the Horizon Europe project HYDRA. The electrochemical data includes GITT, quasi-OCV, and rate capability tests on electrode level as well as rate tests and quasi-OCV on the full-cell level. The parameter set contains geometrical, physical, microstructural, kinetic and transport parameters required to parameterize a P2D cell model (to be uploaded in a later version). The corresponding scientific publication which will also include experimental information on the parameter identification and on the model calibration is currently under preparation and will be linked as well. The repository will be further updated in the future to comprise additional data (e.g. EIS and temperature variation) and more comprehensive data description and meta-data. This dataset supports physics-based modeling and validation of lithium-ion cell models.
