供给端扰动持续发酵，盘面以涨停幅度快速上行

Group 1: Report Overview - Report Title: Supply-side disruptions continue to ferment, and the market rises rapidly by the daily limit - Weekly report on lithium carbonate by Zhongtai Futures' Non-ferrous Metals & New Materials Team (July 27, 2025) [1] - Research Team: An Ran, Wang Haicong [2] Group 2: Industry Investment Rating - Not provided in the document Group 3: Core Views - In July, the overall incremental production from restarts exceeded the reduction from maintenance, but the suspension of Zangge Lithium Industry in the salt lake segment led to a decline in overall production. The downstream demand was mainly based on on-demand procurement, showing differentiation and overall performing better than expected. The price of lithium carbonate rose rapidly, but the high price suppressed downstream demand, and there was also speculative demand. If the production suspension is implemented, it will affect the supply-demand pattern, and the surplus volume will be significantly reduced. If the production suspension expectation is not fulfilled, the fundamental surplus pattern remains unchanged, and the price of lithium carbonate will face a significant decline. In the short term, the price is boosted by news and shows emotional upward movement, and it will mainly fluctuate strongly until the expectation is verified. It is necessary to beware of the price decline risk caused by the failure of the production suspension expectation, and the short-term volatility will continue to increase. It is recommended to wait and see [12][13] Group 4: Section Summaries Part 01: Lithium Carbonate Overview - Supply: The overall incremental production from restarts in July exceeded the reduction from maintenance, but the suspension of Zangge Lithium Industry in the salt lake segment led to a 13.25% decline in salt lake production. The production at the mica end increased by 0.29%, and the production at the recycling end decreased by 0.35%. The import volume remained unchanged [12] - Demand: The weekly apparent demand decreased by 3.64%, and the available days of downstream inventory increased by 0.10%. The overall demand performance was better than expected [12] - Inventory: The lithium ore inventory at ports and warehouses decreased, while the overall inventory increased slightly. The inventory shifted from lithium salt plants to traders, and the surplus pattern continued to accumulate inventory. After the price rose rapidly, the warehouse receipts increased, but the growth rate still needed to be observed [12] - Cost and Profit: The cost of externally purchased spodumene and mica increased, and the profit of externally purchased spodumene decreased by 10.12%, while the profit of externally purchased mica increased by 1.93% [12] Part 02: Lithium Carbonate Industry Chain Prices - Lithium Carbonate Market: The report presents data on the futures and spot prices, basis, trading volume, and open interest of lithium carbonate [16] - Lithium Ore Prices: It shows the prices of spodumene concentrate and lithium mica [16] - Lithium Carbonate Prices: The prices of battery-grade and industrial-grade lithium carbonate, as well as the price difference between them, are provided. The production cost and profit of lithium carbonate are also analyzed [16] - Lithium Hydroxide Prices: The prices of battery-grade and industrial-grade lithium hydroxide and their price differences are presented [16] - Cathode Material Prices: The prices of ternary materials and lithium iron phosphate are shown [16] - Power Battery Cell Prices: The prices of square lithium iron phosphate, cobalt acid lithium, and 523 square ternary cells are provided [16] Part 03: Lithium Carbonate Upstream Supply Environment - Lithium Concentrate: The import volume of lithium concentrate, especially from Australia, is analyzed, including cumulative and monthly data and their changes [62] - Lithium Carbonate: The production capacity, monthly and weekly operating rates, production volume, production volume by raw material, import and export volume, and total supply of lithium carbonate are presented [62] Part 04: Lithium Carbonate Downstream Consumption Environment - Apparent Demand: The apparent consumption of lithium carbonate is analyzed [100] - Real Demand: The production volume, monthly operating rate, and production volume by grade of ternary materials, lithium iron phosphate, cobalt acid lithium, manganese acid lithium, and lithium hexafluorophosphate are presented [100] - Terminal Demand: The production volume, shipment volume, inventory-to-sales ratio, and installation volume of lithium batteries, power batteries, energy storage batteries, and consumer batteries are analyzed. The production and sales of new energy vehicles and their penetration rate, as well as the winning bid scale and capacity of energy storage projects, are also provided [100] Part 05: Lithium Carbonate Inventory Structure - Weekly Inventory: The warehouse receipts by region, smelter inventory, downstream cathode material factory inventory, other inventory, and total inventory of lithium carbonate are presented [194] - Monthly Inventory: The smelter inventory, downstream cathode material factory inventory, and total inventory of lithium carbonate on a monthly basis are analyzed [194] - Upstream and Downstream Inventory: The inventory of lithium ore, finished product inventory of lithium iron phosphate, and finished product inventory of ternary materials are provided [194]
