The electrochemical composition family of a battery used in product, performance, safety, recycling, and passport-data contexts.
Battery chemistry is a practical classification layer for battery-passport data because chemistry affects sustainability attributes, material declarations, performance expectations, recycling routes, and risk interpretation.
This is an editorial implementation term rather than a single formal legal definition. Keep chemistry-family labels separate from EU active material, U.S. 45X electrode active material, battery model, batch, and item identity unless a page explicitly maps those layers.
These entries are non-verbatim context summaries. They are not presented as public legal definitions.
DIN DKE SPEC 99100:2025-02 — Requirements for data attributes of the battery passport
DIN DKE SPEC 99100 uses battery chemistry as implementation context for classifying battery composition in battery-passport data attributes.
Non-verbatim implementation-context summary only; not a verbatim DIN definition. DIN DKE SPEC 99100 is a copyrighted standard, so this page gives context rather than republishing the standard text.
Reference: Section 3.6
Passport and product-data systems should store a chemistry field with an active-material link, chemistry source, test or supplier evidence, model or batch scope, safety implications, and recycling route so downstream users can distinguish chemistry interpretation from complete material disclosure.
Battery chemistry is not just a technical label. It has material-risk, carbon, performance, safety, and recycling implications, so this chemistry-to-evidence control should connect chemistry to the evidence and lifecycle decisions behind the supporting records rather than treat it as a standalone label.
