Core Viewpoint - The article highlights the advancements in solid-state battery technology, particularly focusing on the doping modification of existing solid electrolytes to enhance overall performance, which is crucial for the commercialization of solid-state batteries [1][2]. Group 1: Sulfide Route - The introduction of iodine in sulfide solid electrolytes is becoming a significant direction, improving compatibility with lithium metal anodes and suppressing lithium dendrite growth [3][6]. - The ionic conductivity of iodine-doped sulfide electrolytes has reached 10 mS/cm, operating under pressures below 5 MPa, meeting key application demands [5]. - The supply chain risk is highlighted, as each GWh of solid-state battery requires approximately 90 tons of iodine, contrasting with the 10 tons needed for 1 GW of perovskite solar panels [6][7]. Group 2: Oxide Route - The technology iteration in oxide solid electrolytes is shifting from LATP (Lithium Aluminum Titanium Phosphate) to LLZO (Lithium Lanthanum Zirconium Oxide), with LLZO showing superior performance metrics [8][9]. - LATP is favored for its lower cost, while LLZO offers higher ionic conductivity, a larger electrochemical window, and better chemical stability [9][10]. - The supply chain considerations for LLZO are complex, as it relies heavily on rare earth materials, with China dominating the supply of lanthanum but being highly dependent on imports for zirconium [10][11]. Group 3: Mass Production Challenges - The mass production of LLZO faces significant challenges, particularly in achieving "sintering densification" due to lithium volatility during high-temperature processing [15][16]. - Innovative approaches like ultra-fast sintering (UFS) and pressure-assisted methods are being explored to enhance densification while minimizing lithium loss [17][18]. - Companies are also investigating cost-effective methods, such as direct wet coating of electrolyte slurries on electrodes, to streamline production processes [20]. Group 4: Industry Progress - Companies like Dingsheng Technology have established pilot production lines for sulfide solid electrolytes, indicating progress in scalable supply capabilities [4]. - Domestic firms are actively pursuing innovations to address the challenges of solid-state battery commercialization, paving the way for more robust industrial applications [21].

Core Viewpoint - The environmental equipment sector experienced a slight increase of 0.06% on September 24, with Henghe Co., Ltd. leading the gains, while the overall market indices also showed positive performance [1]. Group 1: Market Performance - The Shanghai Composite Index closed at 3853.64, up 0.83%, and the Shenzhen Component Index closed at 13356.14, up 1.8% [1]. - The environmental equipment sector saw significant individual stock movements, with Henghe Co., Ltd. rising by 29.98% to a closing price of 32.30 [1]. Group 2: Stock Performance - Key stocks in the environmental equipment sector included: - Henghe Co., Ltd. (32.30, +29.98%, 80,400 shares, 248 million CNY) - Xuedilong (8.27, +6.99%, 578,100 shares, 481 million CNY) - Chuxiu Technology (22.72, +4.41%, 18,400 shares, 41.31 million CNY) [1]. - Other notable performers included Jiuwu Gaoke (+3.86%) and Hengrui Environmental (+3.79%) [1]. Group 3: Capital Flow - The environmental equipment sector saw a net inflow of 129 million CNY from institutional investors, while retail investors experienced a net outflow of 146 million CNY [2]. - The capital flow data indicated that Xuedilong had a net inflow of 87.56 million CNY from institutional investors, despite a net outflow from retail investors [3].

Report Summary 1. Report Industry Investment Rating - No information provided about the industry investment rating in the report. 2. Core View of the Report - The lithium carbonate futures rebounded after hitting a bottom. Although the supply pressure remains as the weekly production reached a record high last week, the demand growth is higher than the supply, leading to inventory reduction. It is expected that it is difficult for lithium carbonate to open a downward space in the short - term [10]. 3. Summary by Relevant Catalogs 3.1. Market Review and Operation Suggestions - The lithium carbonate futures hit a bottom and then rebounded. The main contract dropped to a minimum of 72,360 during the session. All industrial products fell during the session, and lithium carbonate futures followed suit, but it turned positive first driven by downstream point - price purchases at low points. The spot electric carbon price remained flat at 73,850, and the spot still had a slight premium over the futures. The price of Australian ore remained flat at 832.5, and the price of lithium mica remained flat at 1,900. The production loss of plants using externally - purchased lithium spodumene narrowed to 2,759, and the production loss of plants using externally - purchased lithium mica remained flat at 8,521. Although salt plants are currently making losses, it does not affect their production enthusiasm [10]. 3.2. Industry News - On September 22, Chile's economic development agency Corfo submitted a resolution to the Comptroller General's Office (CGR) to approve the modification of the contract for the Atacama Salt Lake project with SQM Salar SpA and the OMA mineral lease contract, extending the contract validity to 2030. It also submitted a new mineral lease contract for the Atacama Salt Lake with Codelco and its subsidiary Minera Tarar SpA, with a contract validity from 2031 to 2060. SQM and Codelco are expected to finalize a partnership for the development of the Atacama Salt Field in northern Chile this year, marking the local's first large - scale entry into lithium production [13]. - Jiuzhou Hi - Tech (300631.SZ) announced that it signed a procurement contract worth 81.5 million yuan (including 13% VAT), with a tax - free amount of 72.1239 million yuan, with SDIC Xinjiang Lithium Industry Co., Ltd. for the "Membrane Treatment System Procurement" project of the expansion and renovation project for comprehensive utilization of old brine lithium extraction from the Lop Nur Salt Lake. The signing of this contract is expected to have a positive impact on the company's future performance [13].
