210Ah Prismatic Cell

The AuroraCell 210Ah Sodium-Ion Prismatic Cell is purpose-built for large-scale energy storage systems (ESS), industrial backup power, and grid-level applications where long-term reliability, safety, and efficiency are critical. Delivering 609 Wh of energy at a nominal voltage of 2.9V, this high-capacity sodium-ion battery is engineered to meet the evolving demands of modern energy infrastructure. Whether deployed in utility-scale storage or commercial and industrial (C&I) environments, it provides a stable and scalable foundation for next-generation energy systems.

One of the most important advantages of the 210Ah cell is its drop-in compatibility with standard LFP (LiFePO₄) battery formats. This allows engineers and system integrators to transition to sodium-ion energy storage in Europe without redesigning existing modules, racks, or enclosures. By maintaining the same physical footprint, the AuroraCell 210Ah significantly reduces engineering complexity, shortens development cycles, and accelerates time to market. For companies seeking a cost-effective alternative to lithium-ion batteries, this compatibility is a major operational benefit.

Safety is a defining feature of this prismatic sodium-ion battery cell. Built using advanced NaCrO₂ (Sodium Chromium Oxide) chemistry, it inherently resists thermal runaway, reducing fire risk and improving overall system safety. This is especially important in large-scale installations where safety compliance is non-negotiable. The cell is fully certified with UL9540A, UN38.3, and CE, ensuring it meets the highest international standards for stationary energy storage. These certifications also streamline permitting and regulatory approvals for both indoor and outdoor installations.

Efficiency and longevity are key drivers of performance in energy storage systems, and the AuroraCell 210Ah excels in both areas. With a round-trip efficiency exceeding 96%, it minimizes energy losses during operation, allowing more stored energy to be used effectively. Over its lifespan of more than 20,000 cycles, this high efficiency translates into significant cost savings and improved return on investment (ROI). For operators of grid storage systems, solar energy storage, and peak shaving applications, these gains can have a substantial financial impact.

The cell is designed to perform reliably across a wide range of environmental conditions. Operating between -40°C and +60°C, it maintains over 90% capacity even in extreme cold. This makes it particularly suitable for outdoor deployments in harsh climates, where traditional batteries often require energy-intensive HVAC systems. By reducing or eliminating the need for active temperature control, the 210Ah cell helps lower operational costs and improve overall system efficiency.

From a logistics and safety perspective, the ability to discharge the battery to 0V (zero-voltage shipping) offers a significant advantage. This feature ensures safer transport, simplifies compliance with international shipping regulations, and enables long-term storage without degrading the cell. For large-scale projects requiring bulk shipments, this enhances both safety and supply chain flexibility.

The prismatic design is optimized for laser welding and high-volume manufacturing, ensuring strong, low-resistance electrical connections and efficient module assembly. Combined with local EU stock availability, the AuroraCell 210Ah supports fast delivery across Europe within five working days, making it a reliable choice for time-sensitive projects.

Ideal applications include utility-scale energy storage systems (ESS), telecom infrastructure backup, commercial and industrial peak shaving, renewable energy storage, and remote microgrids. For organizations seeking a scalable, safe, and high-efficiency sodium-ion battery solution, the AuroraCell 210Ah delivers outstanding performance and long-term value.
