1. Report's Investment Rating for the Industry - No investment rating for the industry is provided in the report. 2. Core Viewpoints of the Report - On December 18, 2025, the lithium carbonate futures 2605 contract fell 0.79% to 106,160 yuan/ton. The average price of battery - grade lithium carbonate rose 500 yuan/ton to 97,550 yuan/ton, and the industrial - grade lithium carbonate average price also rose 500 yuan/ton to 94,950 yuan/ton. The battery - grade lithium hydroxide (coarse particles) increased 500 yuan/ton to 85,980 yuan/ton, and the warehouse receipt inventory remained at 15,636 tons [3]. - In terms of supply, the weekly output increased by 47 tons to 22,045 tons. Lithium extraction from spodumene increased by 60 tons to 13,804 tons, lithium extraction from lepidolite decreased by 50 tons to 2,826 tons, lithium extraction from salt lakes increased by 20 tons to 3,095 tons, and lithium extraction from recycled materials increased by 17 tons to 2,320 tons. In December, the output of ternary materials is expected to decline by 7% to 78,280 tons, and the output of lithium iron phosphate is expected to decline by 1% to 410,000 tons. The weekly inventory decreased by 1,044 tons to 110,425 tons, with downstream inventory decreasing by 1,253 tons to 41,485 tons, other - link inventory increasing by 1,280 tons to 50,850 tons, and upstream inventory decreasing by 1,071 tons to 18,090 tons [3]. - The weekly inventory reduction rate has slowed down, and the positive factors have weakened marginally. If the lithium mine projects in Jiangxi resume production and the seasonal off - season factors come into play, the inventory reduction speed may slow down or turn into inventory accumulation, and prices may still face a callback. However, under the strong demand expectation, the downstream's willingness to stock up may also be relatively strong. Attention should be paid to the resumption rhythm, the decline in production scheduling, and whether the strong demand next year can be verified [3]. 3.

The price of battery - grade lithium hydroxide (coarse particles/domestic) was 85,980 yuan/ton, up 500 yuan; the price of battery - grade lithium hydroxide (micropowder) was 90,600 yuan/ton, up 500 yuan; the price of industrial - grade lithium hydroxide (coarse particles/domestic) was 80,330 yuan/ton, up 500 yuan; the price of battery - grade lithium hydroxide (CIF China, Japan, South Korea) was 10.48 US dollars/kg, up 0.03 US dollars [5]. - Other Products: The price of lithium hexafluorophosphate was 170,500 yuan/ton, down 2,500 yuan. The price differences between battery - grade and industrial - grade lithium carbonate, and between battery - grade lithium hydroxide and battery - grade lithium carbonate remained unchanged. The prices of some ternary precursors, ternary materials, lithium iron phosphate, manganese acid lithium, and cobalt acid lithium increased to varying degrees, while some remained unchanged [5]. 3.2 Chart Analysis - Ore Prices: Charts show the price trends of spodumene concentrate (6%, CIF), lepidolite with different Li2O contents, and amblygonite with different Li2O contents from 2024 to 2025 [6][8]. - Lithium and Lithium Salt Prices: Charts show the price trends of metallic lithium, battery - grade and industrial - grade lithium carbonate average prices, battery - grade and industrial - grade lithium hydroxide prices, and lithium hexafluorophosphate prices from 2024 to 2025 [11][13][16]. - Price Differences: Charts show the price differences between battery - grade lithium hydroxide and battery - grade lithium carbonate, battery - grade and industrial - grade lithium carbonate, CIF China, Japan, South Korea battery - grade lithium hydroxide and domestic battery - grade lithium hydroxide, and the basis from 2024 to 2025 [18][20][23]. - Precursors and Cathode Materials: Charts show the price trends of ternary precursors, ternary materials, lithium iron phosphate, manganese acid lithium, and cobalt acid lithium from 2024 to 2025 [26][27][30]. - Lithium Battery Prices: Charts show the price trends of 523 square ternary cells, square lithium iron phosphate cells, cobalt acid lithium cells, and square lithium iron phosphate batteries from 2024 to 2025 [32][35]. - Inventory: Charts show the weekly inventory trends of downstream, smelters, and other links from April 30, 2025, to December 17, 2025 [37][39]. - Production Costs: The chart shows the production profit trends of lithium carbonate from different sources such as外购三元极片黑粉,外购磷酸铁锂极片黑粉,外购锂云母精矿, and外购锂辉石精矿 from 2024 to 2025 [42].
