Report Summary 1. Report Industry Investment Rating No information provided in the content. 2. Core View of the Report - The lithium carbonate futures increased in position and declined in price. Although the lithium futures rose nearly 2000 yuan driven by sentiment yesterday, the spot market did not follow today. The price of electric carbon rose 100 to 64800, and the weak follow - up of the spot price dragged down the performance of the futures during the day. The price of the main contract returned below the spot price again. This week, the weekly output of lithium carbonate decreased by 9.4% to 16630 tons, but the social inventory turned to accumulation again, with a weekly increase of 351 tons to 132000 tons. The inventory accumulation pressure continued to put pressure on the spot price. The poor de - stocking process of lithium carbonate made the short - term rebound of lithium carbonate futures lack fundamental support. However, the current macro - sentiment has improved, and there is an expectation of export rush in the terminal energy - storage lithium battery. So, it is less likely for the lithium carbonate futures to break the previous low in the short term [7]. 3. Summary by Relevant Catalogs 3.1 Market Review and Operation Suggestions - The lithium carbonate futures increased in position and declined. The spot price had weak follow - up, and the main contract price returned below the spot price. The weekly output decreased by 9.4% to 16630 tons, and the social inventory increased by 351 tons to 132000 tons. The short - term rebound of futures lacks fundamental support, but it is less likely to break the previous low in the short term due to improved macro - sentiment and export rush expectation in the terminal [7]. 3.2 Industry News - On May 15, Mitsubishi Chemical's subsidiary MUIS and CATL reached a technology licensing agreement for LIB - related patents [8]. - Scientists from institutions such as the Technical University of Munich in Germany developed a new composite material composed of lithium, antimony, and scandium, with a lithium - ion conduction rate more than 30% higher than existing materials [8]. - Recently, Times Qiji New Energy Technology (Suizhou) Co., Ltd. was established, with a registered capital of 5 million RMB, wholly - owned by Times Qiji Green Energy Technology (Hubei) Co., Ltd., a subsidiary of CATL [9].
