Sentiment in the lithium carbonate spot market was influenced by fluctuations in production, prompting some upstream lithium salt factories to raise their quotes accordingly. The transaction focus for spot purchases by downstream material factories with rigid demand shifted notably upwards, while other material factories maintained their previous lower price points. The psychological expectations of upstream and downstream parties regarding transaction prices continued to diverge. Considering the actual supply-demand situation and cumulative inventory levels for the month, lithium carbonate spot prices may continue to fluctuate within a range.
