Report Title - Carbonate Lithium Daily Review 20250902: Still High Volatility, Pay Attention to Protect Positions [2] Report Industry Investment Rating - Not provided Core View - On September 1, the main contract of lithium carbonate futures declined. The spot market trading was okay, and the basis premium widened. In the cost - end, the price of lithium pegmatite concentrate increased, while the mica price decreased. The lithium carbonate production decreased slightly last week, and the production of lithium carbonate from different raw materials changed little. The production of lithium iron phosphate and ternary materials increased last week. In September, the production scheduling of lithium cobaltate and lithium manganate increased, and the production of power batteries increased last week. The year - on - year growth rate of new energy vehicle production and sales continued in July, but the sales decreased month - on - month. The 3C shipments were average, and the production scheduling of energy - storage batteries increased in September. The inventory of registered warrants increased, and the social inventory decreased. The short - term supply and demand both strengthened. The fundamentals changed little in the short term, and the market was still easily affected by news. It is expected that the lithium carbonate price will fluctuate within a range. It is recommended to conduct short - term range trading, and buy options to protect positions or buy straddle options [3].
