Core Viewpoint - The lithium carbonate main contract surged by 8% amid supply-side disruptions, with concerns over production resumption and stricter environmental regulations in Jiangxi province [3][9]. Supply Side - There is no official announcement for the resumption of production at the Jiangxi site, with the first environmental assessment already publicized and further processes required, potentially delaying resumption until after the Spring Festival [3][9]. - Jiangxi province faces heightened environmental requirements, leading to increased industrial waste treatment costs, which may force smaller producers to exit the market due to inability to bear these costs [3][9]. - Weekly lithium carbonate production increased by 115 tons to 22,535 tons, with specific increases in various extraction methods: spodumene by 35 tons to 13,959 tons, lepidolite by 20 tons to 2,956 tons, brine by 40 tons to 3,185 tons, and recycled materials by 20 tons to 2,435 tons [10][11]. Demand Side - In January 2026, the production of ternary materials is expected to decrease by 5% to 78,180 tons, while lithium iron phosphate production is projected to decline by 10% to 363,400 tons [10][11]. - The production of ternary power batteries is anticipated to drop by 6.15% to 28.7 GWh, and lithium iron power is expected to decrease by 9.77% to 90.01 GWh, while lithium iron energy storage is projected to increase by 0.99% to 63.15 GWh [10][11]. Inventory - The weekly social inventory of lithium carbonate increased by 337 tons to 109,942 tons, with downstream inventory decreasing by 2,458 tons to 36,540 tons, while other segments increased by 2,080 tons to 55,020 tons, and upstream inventory rose by 715 tons to 18,382 tons [10][11].
