Description
1. Product Overview
Spent Lithium Carbonate is a secondary lithium compound recovered from end-of-life lithium-ion battery recycling streams and industrial process residues. Its primary industrial use is as a cost-effective lithium feedstock for cathode precursor manufacturing, ceramics, glass, lubricants, and chemical synthesis. The key value proposition lies in delivering verified lithium content at a lower price point than virgin Li2CO3 while supporting circular economy mandates. It is strategically important as global OEMs and battery gigafactories seek ESG-compliant, secure, non-mining lithium sources to mitigate supply chain risk and meet tightening recycled-content regulations.
