储能大电芯迎来规模化量产元年—CNESA年终盘点

Core Viewpoint - The energy storage industry is transitioning from a focus on "paper parameters" to practical applications, with large capacity battery cells achieving mass production and delivery, indicating a significant shift towards commercial viability and cost efficiency in energy storage systems [2]. Group 1: Mass Production of Large Capacity Battery Cells - Since 2025, several battery companies have reported significant progress in the mass production of 500Ah+ battery cells, with production capacity and delivery rates accelerating [4]. - CATL has initiated mass production of its 587Ah energy storage battery in June, with a production capacity exceeding 22,000 units per day, aiming for 3GWh of shipments by the end of the year [4]. - EVE Energy plans to start mass production of its 628Ah battery by the end of 2024, with a target of 750,000 units in 2025, and has successfully applied it in a 200MW/400MWh independent energy storage project [4]. - Envision AESC has achieved mass production of its 500+Ah battery cells, with plans for next-generation 700Ah+ products [4]. - Hicharge Energy has launched the world's first 1175Ah battery cell and has completed deliveries of its 587Ah battery [4]. - A number of other companies, including Chuang Neng New Energy and Penghui Energy, are also announcing timelines for the mass production of 500Ah+ and 600Ah+ products, indicating a competitive landscape by 2026 [5]. Group 2: Strategic Collaborations and Supply Chain Dynamics - The relationship between system integrators and battery manufacturers is evolving towards long-term, large-scale, and deeply integrated collaborations [7]. - By the end of 2025, significant orders of over 100GWh highlight the importance of supply chain stability and cost control in market competition [7]. - CATL has signed a procurement agreement for no less than 200GWh with a partner, with its 587Ah battery already applied in a 400MW/2400MWh energy storage project [7]. - EVE Energy has established a three-year collaboration for 20GWh with a partner, including 10GWh of large battery cells [7]. - These long-term agreements not only secure production capacity but also indicate a trend towards early collaborative development between systems and battery cells, enhancing overall product performance and safety [7]. Group 3: Global Market Expansion - The competitiveness of China's energy storage industry is being tested globally, with significant progress in the export of 500Ah+ battery cells [9]. - CATL delivered its 587Ah battery for a project in Abu Dhabi, while EVE Energy secured orders in Australia and signed a project agreement for 1GWh [9]. - Hicharge Energy has partnered with a Saudi power company for a 1GW/4GWh energy storage project, utilizing its 1175Ah battery cell [9]. - The export of large battery cells represents not only product output but also the extension of system solutions and standards, opening new opportunities for Chinese energy storage companies in the global long-duration energy storage market [9]. Group 4: Industry Trends and Future Directions - The 500Ah+ battery cells are still in a rapid development phase characterized by diverse sizes and specifications, but there is a consensus that 6MWh+ energy storage systems will accelerate the replacement of previous 5MWh+ solutions, driving down energy storage costs [10]. - The year 2025 is positioned as a pivotal year for large battery cells transitioning from laboratory settings to practical applications in energy storage systems [10].
