News agency reports that on November 14, some investors haveLuxi ChemicalIs the company adding new production capacity for lithium iron phosphate? What is the annual production capacity? Regarding this,Luxi ChemicalOn November 19, it was stated on the investor interaction platform that the company's main products include polyols, caprolactam, nylon 6, organosilicon, formic acid, methylene chloride, methylamine, DMF, polycarbonate, etc., and do not involve lithium iron phosphate.

On November 17, the Nantong City Data Bureau announced the decision to re-approve the Environmental Impact Report for the High-end Polyolefin New Materials Project by Blue Ocean New Materials (Tongzhou Bay) Co., Ltd. (Approval No. Tong Data Approval [2025] 342). The project construction includes: the establishment of one 100,000 tons/year POE unit, one 100,000 tons/year 1-hexene/1-octene unit, one 200,000 tons/year FDPE unit (solution method octene copolymerization), two 25,000 tons/year ethylene-propylene rubber units, two 1000 standard cubic meters/hour water electrolysis hydrogen production units, along with supporting public works and auxiliary facilities.

According to reports from the news agency, on November 17, investors approached...Huitong Co., Ltd.Has the company's humanoid robot solution formed any orders? Which enterprises are cooperating with us? Regarding this,Huitong Co., Ltd.On November 17, the company responded on the investor interaction platform that in the field of robotics, it closely follows industry development trends, focusing on "replacing metal with plastic" to conduct in-depth research on robot lightweighting. It has developed multiple materials such as high-rigidity carbon fiber reinforced materials, high-performance PEEK materials, and continuous fiber composites to meet the application needs of customers in different scenarios. At the same time, focusing on "flexible skin," it has developed multiple materials including injection-molded skin and high-silicon content food-grade elastomer materials. Furthermore, the company continues deep interaction with leading enterprises in the industry around structural components such as optical sensors, tactile sensors, millimeter wave radar, and aesthetic appearance materials, providing material solutions to deliver an exceptional value experience for customers. Currently, the order amount for related business accounts for a small proportion, and this period has no significant impact on the company's operating performance.

On November 17th, the Rongbai Technology 2025 Sodium-ion Battery Cathode Material Launch and Investor Exchange Conference was held in Shenzhen. Wang Zunzhi, General Manager of Rongbai Technology's Sodium Battery Division, introduced that sodium-ion batteries, with their high safety, ability to operate at wide temperatures, long cycle life, and high cost-effectiveness throughout the lifecycle, can be applied to many scenarios where lithium batteries cannot penetrate. In the context of global energy transition and surging demand for energy storage, the market size for sodium-ion battery cathode materials is expected to reach hundreds of billions in the next decade. Currently, Rongbai Technology has achieved comprehensive coverage of sodium battery technology routes, leading the industry in key indicators such as cycle life, compaction, and energy density, all of which have been mass-produced.

The Tianyancha App shows that recently, the patent applied for by Xiaomi Automobile Technology Co., Ltd. for "lightweight design method, device, electronic equipment, and program product for vehicle structure" has been published. The abstract shows that the present disclosure relates to the field of vehicle technology, including establishing a macro mechanical representation by obtaining a finite element model of the components in the vehicle corresponding to the components. By reflecting the microcrystalline arrangement characteristics of the components combined with the beam element crystal structure of the components, a topological model of the components is constructed, and a topological analysis is performed on the topological model to obtain the topological analysis results. By combining the microcrystalline arrangement characteristics and macro mechanical representation, lightweight design of the topological analysis results can be achieved from microscopic lattice arrangement to macroscopic structural form, thereby realizing lightweight design of vehicle structures.
