210Ah Prismatic Cell

The 210Ah sodium-ion prismatic cell is designed for large-scale energy storage systems, industrial backup power and grid-level applications. With 609 Wh of nominal energy and a nominal voltage of 2.9V, the cell gives battery developers and system integrators a high-capacity sodium-ion format for stationary storage, commercial energy systems and infrastructure projects.

The 210Ah sodium-ion prismatic cell supports applications where long service life, stable operation and system-level safety matter. Its prismatic format makes it suitable for module, rack and containerized battery designs. This makes the cell relevant for energy storage systems, renewable energy integration, commercial and industrial storage, telecom backup, remote microgrids and grid-support applications.

One practical advantage of the 210Ah cell is its compatibility with standard LFP battery formats. This can help engineers evaluate sodium-ion technology without completely redesigning existing module, rack or enclosure concepts. By keeping a familiar physical format, the cell can reduce engineering complexity and support faster development for sodium-ion energy storage projects in Europe.

The cell uses NaCrO₂ sodium chromium oxide chemistry, which supports stable operation and a safety-focused battery architecture. This makes the 210Ah sodium-ion prismatic cell suitable for stationary storage projects where thermal behaviour, reliability and compliance planning are important. The cell is certified according to UL9540A, UN38.3 and CE requirements, supporting use in regulated energy storage applications.

Efficiency is also important in stationary storage. With round-trip efficiency above 96%, the 210Ah cell helps reduce energy losses during charge and discharge cycles. In long-duration energy storage systems, lower losses can support better system performance and more efficient operation over time.

The 210Ah sodium-ion prismatic cell is designed for long service life, with more than 20,000 cycles under suitable operating conditions. This makes it relevant for applications with frequent cycling, such as solar energy storage, peak shaving, grid balancing, commercial backup power and industrial energy buffering.

The cell operates across a wide temperature range from -40°C to +60°C. It also maintains more than 90% capacity at -40°C, which makes it suitable for outdoor installations and cold-climate energy storage projects. In suitable system designs, this low-temperature performance can reduce the need for additional thermal management.

From a logistics perspective, the cell supports 0V zero-voltage shipping. This helps simplify transport, storage and inventory planning for manufacturers, distributors and project teams. It also gives customers more flexibility when managing large project volumes or long-term stock.

The prismatic design supports laser welding and high-volume module assembly. This helps create strong electrical connections and supports efficient production workflows for battery modules, racks and larger energy storage systems.

AuroraCell supports European customers with local EU stock availability and standard delivery options, subject to stock and project requirements. For companies evaluating sodium-ion technology for stationary storage, the 210Ah sodium-ion prismatic cell offers a high-capacity option for testing, system integration and project-specific energy storage development.
