SHANGHAI, Sep 18 (SMM) – Lithium carbonate price declined in the week ending September 14. The overall supply and demand situation for lithium carbonate remained weak recently. However, there was a gradual differentiation in the trends between industrial-grade and battery-grade lithium carbonate. In terms of battery-grade lithium carbonate, lithium prices have continued to decline recently. The manufacturing cost of some major lithium carbonate smelters who use spodumene as raw material was lower than its selling price, and this inversion trend was expanding. Moreover, we are approaching the negotiation period for Q4 mining contracts, and the market still held relatively high expectations for future mining prices. As a result, some companies had a stronger intention to maintain prices and had temporarily suspended quoting prices to the market, leading to reduced market transactions and a relatively sluggish market. For industrial-grade lithium carbonate, there has been an increase in market circulation recently, resulting in more selling pressure and downward pressure on prices in the short term.
