融捷能源：下一代储能电芯技术，向大容量、高效率、长循环演进

Core Viewpoint - The presentation by Liu Wen from Rongjie Energy at the 2025 Starting Point Lithium Battery Industry Annual Conference highlights the current state and challenges of the household energy storage industry, while showcasing the company's technological solutions and future development paths for energy storage cells [6][16]. Industry Overview - The household energy storage industry presents significant advantages in reducing electricity costs, enhancing emergency backup capabilities, and achieving autonomous energy management, but it faces challenges such as battery consistency, capacity management issues, high installation and maintenance costs due to complex system integration, and safety and reliability risks [6][7]. Technological Solutions - Rongjie Energy has developed a diverse matrix of energy storage cells, including 72Ah, 100Ah, 102Ah, 280Ah, 314Ah, and 588Ah, to meet various application needs. The 72Ah and 102Ah cells can achieve over 6000 cycles at a 1C rate, while the 314Ah cell targets long-life requirements with up to 9000 cycles at 0.5C [9][10]. Next-Generation Energy Storage Cell Technology - The evolution of energy storage cells is moving towards larger capacities (over 500Ah), higher energy efficiency (from 93% to over 96%), and longer cycle life (from 8000 to 12000 cycles). Industry standards are transitioning from early adaptations of power battery standards to dedicated mandatory standards like GB 44240-2024 [12][13]. Cost Reduction Strategies - To address market demands for high safety and low costs, Rongjie Energy focuses on reducing initial investment and operational costs. The company has improved the packing density of cathode materials from 2.4 g/cm³ to 2.6 g/cm³, enhancing energy density [13][14]. Conclusion - Liu Wen's presentation outlines a clear evolution blueprint for Rongjie Energy's household storage products, addressing current pain points and future demands. The company is driving advancements in safety, longevity, and cost-effectiveness through material innovation, process optimization, and system integration, thereby reconstructing the energy storage value chain [16].
