== Scope == | |||
This record contains raw data from the constant-current discharge of a [[:Category:OSWb61b96acf2f44b7482d5565fe3a2d88b|CR2032]] lithium coin cell at 11 mA. The test was performed using a [[Item:OSW4956eab590f649c18139b1f292cc836f|BioLogic]] battery cycler with data recorded at 1-second intervals. The CR2032 cell is manufactured by [[Item:OSW249dcc24b5ab4916a8e5f813fe44cb44|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. | |||
