A Battery Passport is a data-access and product-information layer. A lithium vault is the source-evidence layer beneath it. Lithium Record preserves uploaded files, hash values, source URLs, and handoff notes that may support passport workflows while keeping regulated passport creation, access control, and data responsibility with the operator and its chosen systems. 1
This is a pillar page for the Lithium compliance evidence cluster. It should act as the hub that spoke pages cite and return to.
Why the vault layer matters
Passport data becomes fragile when the source file disappears or the supplier context is lost. Lithium inputs touch carbon footprint, recycled content, provenance, due diligence, material identity, and end-of-life records. A vault page can hold the evidence behind those data fields and make each file reviewable. That is a different function from issuing a Battery Passport.
Battery Regulation context
Regulation (EU) 2023/1542 introduces digital battery passport obligations for relevant battery categories and links those obligations to product information, sustainability, and lifecycle data. Lithium Record can support the evidence chain by publishing stable URLs and hashes for source documents. It does not decide access rights, create official identifiers, or satisfy passport obligations by itself.
Data-field discipline
Each passport-supporting page should identify a data field, the lithium source file behind it, the issuer, the file date, the upload date, the hash, and the limitation. If the source file supports carbon data, it should link to the carbon pillar. If it supports origin or due diligence, it should link to provenance pages. This prevents orphan data fields.
Spoke structure
The spokes below separate source URLs, passport data fields, recycled-content files, verifier access, and retention logic. Together they form the operational bridge between uploaded lithium evidence and downstream passport workflows.
