1. Report Industry Investment Rating - Not provided in the document 2. Core Viewpoints of the Report - Short - term lithium carbonate prices may stabilize due to policy expectations, but the high - inventory and oversupply situation remains unchanged. The downward trend in the cost side opens up price space, and it is expected to maintain a weak oscillation [12] 3. Summary by Directory 3.1 Viewpoint Overview - The short - term price of lithium carbonate may be affected by policy expectations and stabilize, but the high - inventory and oversupply pattern persists, and the cost decline allows for price drops, with a forecast of weak oscillation [12] 3.2 Balance Sheet 3.2.1 Global Balance Sheet - From 2018 to 2025E, global lithium demand has been growing, with the global effective lithium demand reaching 142.3 million tons in 2025E, a year - on - year increase of 29%. Global lithium supply has also been increasing, with the global effective lithium supply reaching 165.0 million tons in 2025E, a year - on - year increase of 13%. The global lithium market shows a trend of changing from surplus to shortage and then back to surplus, with a surplus of 22.7 million tons in 2025E, accounting for 16% of the total demand [15] 3.2.2 Domestic Balance Sheet - In 2024 - 2025, the supply and demand of domestic lithium carbonate are both increasing. In May 2025E, the total supply of lithium carbonate is expected to be 91,250 tons, and the total demand is expected to be 90,421 tons, with a supply - demand difference of 829 tons [16] 3.3 Fundamental Data 3.3.1 Supply and Demand - In April, the estimated total supply of lithium carbonate was 89,560 tons, and the total demand was 87,292 tons, with a supply - demand difference of 2,268 tons. In May, the estimated total supply was 91,250 tons, and the total demand was 90,421 tons, with a supply - demand difference of 829 tons [10] 3.3.2 Inventory - According to SMM data, the monthly inventory in April was 96,202 physical tons, including 45,169 physical tons of downstream inventory and 51,033 physical tons of smelter inventory. The weekly inventory this week was 131,920 physical tons, including 56,522 physical tons of smelter inventory, 41,428 physical tons of cathode factory inventory, and 33,970 physical tons of battery and trader inventory. According to Baichuan data, the lithium carbonate factory inventory was 34,785 tons [10] 3.3.3 Price Difference - On May 16, the spot price of battery - grade lithium carbonate was 64,500 yuan/ton, a month - on - month decrease of 1.15%, the futures price was 61,800 yuan/ton, and the basis was 2,700 yuan/ton [10]

碳酸锂周报 供应压力仍存，价格延续偏弱 长江期货股份有限公司交易咨询业务资格：鄂证监期货字[2014]1号 【产业服务总部|有色中心】 资深研究员：李 旎 执业编号：F3085657 投资咨询号: Z0017083 2025/4/28 需求端：4月整体排产预计环比持平。3月，我国动力和其他电池合计产量为118.3GWh，环比增长18.0%，同比增长54.3%。动力和 其他电池合计出口23.0GWh，环比增长8.8%，同比增长75.3%。动力和其他电池销量为115.4GWh，环比增长28.3%，同比增长 64.9%。以旧换新政策出台和政策端新能源车购置税的延期也有望持续支撑中国新能源车市场销量的较快增长。 库存：本周碳酸锂库存呈现累库状态，工厂库存周内增加2860吨至32560吨，市场库存减少3722吨，广期所库存增加2233吨。 ⚫ 策略建议： 从供应端来看，碳酸锂产量稳增，3月产量环比增加24%，近期锂盐厂稳定生产，3月锂精矿进口量环比减少6%，3月锂盐进口环 比增加47%，预计后续南美锂盐进口量保持高位。从需求端来看，受储能和电动车终端增速的带动，下游需求较好，但美国对等关税 政策落地对锂电池出口形成负面 ...
