SMM Daily Review: Spot Lithium Carbonate Prices Remained Stable on April 16 The SMM battery-grade lithium carbonate index price stood at 71,638 yuan/mt, up 54 yuan/mt from the previous working day. Battery-grade lithium carbonate was quoted at 70,200-72,900 yuan/mt, with an average price of 71,550 yuan/mt, unchanged from the previous working day. Industrial-grade lithium carbonate was quoted at 69,150-70,150 yuan/mt, with an average price of 69,650 yuan/mt, also unchanged from the previous working day. The price center of spot lithium carbonate transaction prices remained stable today. Currently, downstream material plants have a high proportion of long-term contracts and customer supply, resulting in weak demand for spot orders. With no clear guidance on future demand, they mainly make just-in-time procurement and have no inventory plans. Although upstream lithium chemical plants have slightly loosened their offers, there remains a significant gap with downstream's expected purchase prices. Overall, market transactions remained relatively sluggish.
