库存继续去化，碳酸锂盘面宽幅震荡

Group 1: Market Analysis - On December 4, 2025, the main contract 2605 of lithium carbonate opened at 93,800 yuan/ton and closed at 93,700 yuan/ton, with a -1.26% change in the closing price compared to the previous day's settlement price. The trading volume was 663,458 lots, and the open interest was 560,629 lots, down from 562,836 lots the previous day. The current basis was 760 yuan/ton (average price of electric carbon - futures). The lithium carbonate warehouse receipts were 10,422 lots, a change of 770 lots from the previous trading day [1] Group 2: Spot Market - According to SMM data, the price of battery - grade lithium carbonate was 92,200 - 95,800 yuan/ton, a change of -350 yuan/ton from the previous trading day, and the price of industrial - grade lithium carbonate was 90,500 - 92,600 yuan/ton, also a change of -350 yuan/ton. The price of 6% lithium concentrate was 1,175 US dollars/ton, a change of -30 US dollars/ton from the previous day [2] - The downstream material factories' inquiry and trading activities are becoming more active. The annual long - term contract negotiations between upstream and downstream enterprises are still ongoing, with the focus on next year's price coefficient and procurement volume [2] - In December, the domestic lithium carbonate production is expected to continue to grow, with a month - on - month increase of about 3%. In terms of demand, new energy vehicle sales in December are expected to be strong, and the energy storage market will continue to have strong supply and demand with a tight supply situation. The production schedules of cells and cathode materials in December are expected to remain high but decline slightly month - on - month. Overall, lithium carbonate will continue to be destocked in December, but the destocking rate will slow down compared to November [2] - According to the latest weekly data, the weekly production increased by 74 tons to 21,939 tons, the production from spodumene and mica slightly increased, and the production from salt lakes slightly decreased. The weekly inventory decreased by 2,366 tons to 113,602 tons. The inventory in smelters and other links decreased, while the inventory in downstream links increased, and the consumer end still performed well [2] Group 3: Strategy - The market fluctuated widely on the day, inventory continued to be destocked, and consumption provided some support. The resumption of production at the mine end is in progress and is expected to gradually resume. There are significant differences in the consumption forecast for the first quarter, with expected decreases in the power battery segment and high levels in the energy storage segment. Attention should be paid to the inflection points of consumption and inventory [3] - For the single - side strategy, short - term waiting and seeing is recommended. There are no strategies for options, inter - period, cross - variety, and spot - futures operations [3][4]
