Report Summary 1. Report Industry Investment Rating - No information provided 2. Core Viewpoints - Short - term supply - demand mismatch drives up the price of lithium carbonate; in the medium - long term, increased production may suppress futures prices. High demand stimulates downstream to increase lithium carbonate purchases, leading to a reduction in social inventory [3] 3. Summary by Related Catalogs Lithium Compounds - SMM battery - grade lithium carbonate average price is 74,100 yuan/ton, up 100 yuan; SMM industrial - grade lithium carbonate average price is 71,850 yuan/ton, up 100 yuan.
