Core Viewpoint - Enjie Co., Ltd. (002812) announced on August 5 that its electrolyte powder types exhibit varying ionic conductivity and particle sizes, with the highest ionic conductivity reaching 16 mS/cm, and particle sizes ranging from 0.3 μm to 15 μm, indicating a leading position in the domestic market [1] Summary by Relevant Categories Product Performance - The company’s electrolyte powder can achieve ionic conductivity as high as 16 mS/cm, with the finest particle size of 0.3 μm also reaching a conductivity of 6 mS/cm, which is considered a domestic leading level [1] - Different ionic conductivities and particle sizes can be applied in the anode, electrolyte layer, and cathode, depending on customer requirements and application scenarios [1] Technical Insights - The variation in ionic conductivity among different electrolytes is attributed to changes in their components, and there is no direct correlation between conductivity and production yield [1] - The inherent properties of different component electrolytes determine their ionic conductivity [1]

Group 1: Product Characteristics - The company's sulfide solid electrolyte membrane is not a skeleton membrane and does not require a skeleton support, consisting only of electrolyte and adhesive, achieving a tensile strength of 1.2 MPa [2] - The electrolyte powder types have varying ionic conductivities, with the highest reaching 16 mS/cm and the smallest particle size of 0.3 μm achieving 6 mS/cm, which is considered leading in the domestic market [5] Group 2: Production Processes - The electrolyte membrane production process includes dissolving the adhesive in a solvent, mixing it with electrolyte powder, and coating it onto a substrate to form a roll [3] - The core process for producing electrolyte powder involves solid-phase sintering, with key steps including mixing, sintering, and fine grinding [4] - The company employs a carbon thermal reduction method for lithium sulfide production, which is safe and suitable for large-scale production [6][7] Group 3: Quality and Application - The company can achieve lithium sulfide purity of 99.9% using carbon thermal reduction, while also providing samples of 99.5% purity, which meets electrolyte preparation needs [7] - Different ionic conductivities and particle sizes of the electrolyte powders do not correlate with production yield, as their performance is determined by the inherent properties of the components [5]
