SHANGHAI, Jun 13 (SMM) - The prices of lithium carbonate rose slightly last week. Thanks to a surge in the planned output of LFP plants, the lithium carbonate market could potentially shift back to a small supply deficit this month. Both inquiries and transactions increased last week. The recovery of end demand encouraged major smelters to raise their offers slightly. Some small and medium-sized smelters and traders either held back from selling or hiked their quotations considerably amid bullish sentiment. Battery material factories purchased primarily under long-term orders, while a few small and medium-sized producers had to accept higher prices in order to secure the supply. The market prices are expected to go up further with the recovery of the demand.
