Core Viewpoint - The 2025 Fifth Chang'an Two-Wheeled Vehicle Battery Exchange Conference focuses on advanced technologies in the two-wheeled vehicle and battery exchange industry, gathering over 300 key enterprises and 600 executives to discuss industry development. Group 1: Event Overview - The conference was held on July 11, 2025, in Shenzhen, organized by various entities including Qidian Lithium Battery and Qidian Solid-State Battery [1] - The forum emphasized discussions on cutting-edge technologies such as lithium batteries, sodium batteries, high-rate charging, and new materials [1] Group 2: Company Insights - Star恒电源 has developed a comprehensive battery manufacturing and recycling business over 20 years, with production bases in Suzhou and Chuzhou, and international factories in Hungary and Indonesia [4] - The current production capacity is 2.25 GWh in Suzhou and 8 GWh in Chuzhou, with an upcoming expansion of 4 GWh [5] Group 3: Material Innovations - The company focuses on manganese-based materials, particularly lithium manganese oxide, which offers good ionic conductivity and stability, making it suitable for two-wheeled vehicles [5] - The first-generation single crystal Mn3O4 precursor material developed by the company enhances performance by 50% compared to traditional materials, reducing processing costs [5] - Lithium iron manganese phosphate is another material being explored, which has a voltage platform around 3.8V and is cost-effective [6] Group 4: Production Methods - Two main production methods for manganese-based materials are discussed: liquid phase methods (e.g., co-precipitation, sol-gel) and solid phase methods (e.g., high-temperature solid-state) [8] - Liquid phase methods offer better material uniformity but are complex, while solid phase methods are simpler and more cost-effective but may result in lower quality [8] Group 5: Advanced Technologies - The company introduced its seventh-generation technology, "Super Lithium S7," which combines the advantages of various manganese-based materials and has been successfully applied in over 200,000 vehicles [9] - The development of a precursor material platform aims to produce high-purity manganese oxides and transition metal oxides, with significant production capabilities planned for 2026 [10]
