价格快速上涨，警惕非理性风险

1. Report Industry Investment Rating - The investment ratings for industrial silicon, polysilicon, and lithium carbonate are all "oscillating" [7][8][82] 2. Core Viewpoints of the Report - The prices of industrial silicon, polysilicon, and lithium carbonate in the new energy industry are all expected to oscillate. Industrial silicon has increasing supply, decreasing demand, and fluctuating inventory; polysilicon has a speculative sentiment, and its supply and demand will both decrease in December, but the supply - demand pattern is expected to improve; lithium carbonate has strong terminal demand, and the industrial chain is in a game over long - term contract prices, with short - term price increases and risks of chasing high prices [7][8][82] 3.

Although the supply and demand will both decrease in December, the supply - demand pattern is expected to improve, but there is a speculative sentiment in the short term [8] 3.3 Lithium Carbonate (LC) - Supply Side: The national weekly production is 22,200 tons, a week - on - week increase of 0.53%. The production in November was 95,400 tons, a month - on - month increase of 3.35% and a year - on - year increase of 49.00%; the planned production in December is about 98,200 tons, a month - on - month increase of 3.00% and a year - on - year increase of 40.97% [82] - Import Side: In November, the import volume of lithium carbonate was 22,100 tons, a month - on - month decrease of 7.64% and a year - on - year increase of 14.66%. The import volume of lithium concentrate was 677,500 tons, a month - on - month increase of 27.59% and a year - on - year increase of 40.42% [82] - Material Demand: The weekly production of lithium iron phosphate is 101,000 tons, a week - on - week decrease of 3.08%, and the weekly production of ternary materials is 19,800 tons, a week - on - week increase of 0.25% [82] - Terminal Demand: In November, the production and sales of new energy vehicles increased year - on - year. From January to October, the cumulative bidding for energy storage was 201.5GWh, a year - on - year increase of 44%, and the cumulative winning bids were 153.2GWh, a year - on - year increase of 170.67% [82] - Inventory Side: The social inventory (including warehouse receipts) is 10,980 tons, a week - on - week decrease of 0.59%, and the lithium salt factory inventory is 17,900 tons, a week - on - week decrease of 1.32% [82] - Cost and Profit: The cash production cost of lithium mica for external ore purchase is 109,946 yuan/ton, a week - on - week increase of 10.18%, and the production profit is - 9,014 yuan/ton, a week - on - week decrease of 2,986 yuan/ton [82] - Investment Viewpoint: The price is expected to oscillate.
