现货和期货价格同步维持跌势，但现货价格跌幅放缓，基差整体呈小幅走弱趋势。截至5月19日，SMM 电池级碳酸锂现货均价为6.37万元／吨，工业级碳酸锂均价为6.21万元／吨，环比跌幅分别为1.39%和 1.43%。整体上，现货市场心态偏悲观，交投观望情绪较浓。 库存高位施压。上周全环节库存整体小幅增加，其中上游冶炼厂库存累积明显，下游库存略有减少，其 他环节贸易商库存稳中小幅减少。根据SMM的数据，截至5月15日，样本周度库存总计13.19万吨，冶 炼厂库存为5.65万吨，下游库存为4.14万吨，其他环节库存为3.40万吨。SMM样本4月总库存为9.62万 吨，其中样本冶炼厂库存为5.10万吨，样本下游库存为4.52万吨。 供给宽松持续。虽然有部分上游企业在4月和5月进行了减停产，但随着上游陆续复产，叠加海外矿到港 量攀升，供应压力仍然显著，最新产量数据基本维持高位。另外，自云母提锂产能复产以来，上游供应 稳步增长，各原料提锂投产节奏稳定，在一体化降本趋势下，上游难以快速出现大规模减停产。 近日碳酸锂期货盘面持续走弱，空头氛围有所强化。截至5月20日收盘，碳酸锂主力合约2507已下跌至 6.086万元／吨。一方 ...

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core View of the Report The supply - demand contradiction of lithium carbonate remains unresolved, and the pattern of weak oscillation may continue. The expansion inertia after the Spring Festival and the current stall in demand dominate the market. The spot market has default news, and there are also some differences within the short - selling funds in the futures market. It may enter a bottom - seeking stage in the short term [2][4]. 3. Summary by Relevant Catalogs 3.1 Daily Market Summary - The price of the lithium carbonate main contract on May 8 was 64,280 yuan/ton, a slight increase of 0.19% from the previous day, but it showed an oscillating downward trend in the past five days, dropping from 66,260 yuan/ton to 64,280 yuan/ton [2]. - The basis weakened significantly, reaching 2,120 yuan/ton on May 8, a decrease of 620 yuan/ton from the previous day [2]. - The position of the main contract decreased for two consecutive days, dropping to 267,396 lots (-3.43%) on May 8, while the trading volume increased significantly by 51.75% to 309,284 lots [2]. - The market price of battery - grade lithium carbonate dropped to 66,400 yuan/ton (-0.75%), and the industrial - grade lithium carbonate also declined. The price center of the industrial chain spot continued to move down [2]. - The prices of downstream products such as lithium hexafluorophosphate, power ternary materials, and lithium iron phosphate decreased by 1.09%, 0.3%, and 1.04% respectively, and the prices of electrolyte and anode materials also weakened [2]. 3.2 Industry Chain Supply - Demand and Inventory Analysis - In April, the total output of lithium carbonate decreased by 7% month - on - month but remained at a high level. The output of spodumene decreased by 16%, that of lithium mica increased by 4% month - on - month, and the output of salt lakes increased by 10% with the warming of the temperature [3]. - The price of lithium salts forced the mining end to make concessions, and severely hit the smelting demand such as toll - processing. The mining end is currently in a stage of price decline and inventory accumulation [3]. - From April 1 - 30, the retail sales of new energy passenger vehicles in the country were 922,000 units, a year - on - year increase of 37% and a month - on - month decrease of 7%; the wholesale volume of manufacturers was 1.142 million units, a year - on - year increase of 41% and a month - on - month increase of 1% [3]. 3.3 Industry Chain Price Monitoring - On May 8, 2025, compared with May 7, 2025, the price of the lithium carbonate main contract increased by 0.19%, the basis decreased by 22.63%, the main contract position decreased by 3.43%, and the main contract trading volume increased by 51.75%. The market price of battery - grade lithium carbonate decreased by 0.75%, while the prices of spodumene concentrate and lithium mica concentrate remained unchanged. The prices of lithium hexafluorophosphate, power ternary materials, and lithium iron phosphate decreased by 1.09%, 0.3%, and 1.04% respectively [6]. - From May 2 to April 25, 2025, the capacity utilization rate of lithium carbonate decreased by 0.48% [6]. 3.4 Industry Dynamics and Interpretation - On May 8, the SMM battery - grade lithium carbonate index price was 65,346 yuan/ton, a decrease of 1415 yuan/ton from the previous working day. The average price of battery - grade lithium carbonate was 65,250 yuan/ton, and that of industrial - grade lithium carbonate was 63,600 yuan/ton, both decreasing by 1400 yuan/ton. Due to high inventory and weak downstream procurement, the spot price of lithium carbonate continued to fall [7]. - From April 1 - 27, the retail sales of new energy passenger vehicles in the country were 728,000 units, a year - on - year increase of 24% and a month - on - month decrease of 10%, with a retail penetration rate of 52.3%. The wholesale volume of manufacturers was 846,000 units, a year - on - year increase of 25% and a month - on - month decrease of 6%, with a wholesale penetration rate of 53.9% [8]. 3.5 Industry Chain Data Charts The report provides multiple data charts, including those on lithium carbonate futures main contract and basis, battery - grade and industrial - grade lithium carbonate prices, lithium concentrate prices, lithium hexafluorophosphate and electrolyte prices, ternary precursor prices, ternary material prices, lithium iron phosphate prices, lithium carbonate inventory, lithium carbonate operating rate, and cell selling prices [9][14][17][19][21][22][24][26][28].
