Battery Ontology
================================

Welcome to the **EMMO Battery Domain Ontology**, a semantic resource with essential terms and relationships to describe battery cells, materials, methods, and data. **Here's a simple example:**

.. tab-set::

   .. tab-item:: JSON

      .. code-block:: json
         :linenos:

         {
            "@context": "https://w3id.org/emmo/domain/battery/context.json",
            "@type": "CR2032",
            "schema:name": "My CR2032 Coin Cell",
            "schema:manufacturer": {
               "@id": "https://www.wikidata.org/wiki/Q3041255",
               "schema:name": "SINTEF"
            },
            "hasProperty": {
               "@type": ["NominalCapacity", "ConventionalProperty"],
               "hasNumericalPart": {
                     "@type": "Real",
                     "hasNumericalValue": 230
               },
               "hasMeasurementUnit": "emmo:MilliAmpereHour"
            }
         }
