Guide to Battery-Grade Lithium Carbonate & Hydroxide

Lithium Extraction and Refining for Electric Vehicle Batteries

Aug 04, 2026

• Introduction: Hard-rock (Spodumene) vs. Salar Brine processing pathways.
• Direct Lithium Extraction (DLE):
- Adsorption, ion-exchange, and solvent extraction mechanisms.
- Reducing water usage and yield recovery timelines from months to hours.
• Refining Chemical Grade Products: Converting raw extract to Battery-Grade Lithium Carbonate (Li2CO3) and Lithium Hydroxide (LiOH·H2O).
• Purity Benchmarks: Meeting strict iron, sodium, and heavy metal limits for high-nickel cathode synthesis.
