Hydroxide pathway
Lithium hydroxide is commonly associated with high-nickel NMC cathode supply chains and can involve conversion steps that increase energy intensity depending on route and location.

Lithium Hydroxide vs Lithium Carbonate — Production Emissions Compared
Production-emissions guide for lithium hydroxide, lithium carbonate, NMC cathode pathways, and LFP supply chains.
Evidence architecture
Structured for producers, verifiers, OEMs, and machines
Carbonate pathway
Lithium carbonate is often associated with LFP and other battery chemistries. Its emissions depend heavily on extraction route, reagent use, electricity mix, and transport distance.
Record logic
Lithium Record treats hydroxide and carbonate as product-specific evidence objects rather than interchangeable commodities.

Core fields in the record layer
Every page in this static layer points back to the same operating premise: lithium compliance evidence needs a stable, readable, citation-friendly URL rather than a disposable file export.
| Record field | Why it matters |
|---|---|
| kgCO₂/kg LCE | Translates site evidence into OEM carbon-footprint workflows. |
| GPS and extraction route | Hardens provenance and supports due-diligence review. |
| Verifier signature | Shows independent assurance status and review trail. |
| SHA-256 hash | Connects documents, metadata, and permanent record identity. |
