This dataset was used as an example in the Battery2030+ Excellence Seminar, "How Semantic Technology Accelerates Battery Innovation" by Dr. Simon Clark.

Scope

This record contains raw data from the constant-current discharge of a CR2032 lithium coin cell at 11 mA. The test was performed using a BioLogic battery cycler with data recorded at 1-second intervals. The CR2032 cell is manufactured by VARTA and was tested in ambient laboratory conditions. The dataset is intended to demonstrate ontology-based linked data reporting that is also consistent with the FAIR principles. RDF metadata is made available in metadata.jsonld and metadata.html formats.
