Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core View The current supply and demand of lithium carbonate are both strong, and the upstream inventory pressure is not significant. With the active resumption of key mines, the expectation of supply contraction has weakened. It is expected that the price of lithium carbonate will fluctuate at a low level. [1] 3.
