300Ah+储能电芯竞争迈入2.0：瑞浦兰钧392Ah量产“接棒”

Core Viewpoint - The article highlights the rapid development and competitive advantages of the new 392Ah energy storage cell from Ruipu Lanjun, emphasizing its low modification cost, short cycle time, and quick ramp-up to mass production, which positions it favorably in the evolving 300Ah+ energy storage market [1][15]. Group 1: Market Trends and Product Development - The competition in the 300Ah+ energy storage cell market is entering a 2.0 era, with major manufacturers expected to complete new product launches and mass production plans between 2023 and 2024. The capacity switch rate from 280Ah to 314Ah cells among leading manufacturers is projected to reach 52% by early 2024 [2]. - By the second half of 2024, large-scale bidding for 314Ah cells is anticipated, with a market penetration rate of 40% for these cells in commercial energy storage products [2]. - GGII forecasts that the penetration rate of 314Ah cells will exceed 70% by 2025, indicating a growing acceptance in the mainstream market and opening doors for the commercialization of 300Ah+ energy storage cells [3]. Group 2: Product Features and Performance - The new 392Ah energy storage cell from Ruipu Lanjun boasts an energy density of 415Wh/L, a cycle life of over 12,000 cycles, and an energy efficiency of 95%, making it a strong contender in the 300Ah+ energy storage cell market [4][16]. - The Powtrix™ 6.26MWh energy storage system, developed alongside the 392Ah cell, reduces the number of battery clusters by 50%, increases energy density by 20%, and saves 16% in footprint, while also shortening operational time by 18% compared to the 5MWh system [4][22]. - The 392Ah cell's design allows for minimal size changes, enhancing compatibility with existing production lines and processes, which improves safety, reliability, and manufacturability [14]. Group 3: Safety and Reliability - The 392Ah cell incorporates advanced safety features, including a zero-tab redundancy design that enhances energy efficiency and stability, reducing potential safety risks and ensuring long-term stable operation [16][18]. - The cell has passed GB 44240-2024 shallow puncture tests, confirming its fire and explosion resistance [17]. - The thermal runaway temperature of the 392Ah cell is comparable to that of the 314Ah product, demonstrating its maturity and reliability in safety standards [18]. Group 4: Market Demand and Future Outlook - The 392Ah cell is positioned to fill a gap in the next-generation energy storage cell market, with a balanced performance in safety, manufacturability, longevity, energy density, and cost [11]. - By 2024, the domestic market for long-duration energy storage (4 hours and above) is expected to reach approximately 15GW/63GWh, accounting for over 25% of total energy storage bidding, indicating a growing demand for such solutions [24]. - Ruipu Lanjun's collaboration with various mainstream automotive and energy storage manufacturers has led to a monthly shipment of over 2GWh of the new battery technology, reflecting strong market traction [9].
