Why Sodium-Ion Technology with AuroraCell

Sodium-ion batteries are a key building block for the next generation of safe, sustainable and cost-effective energy storage systems. AuroraCell focuses on this technology because it aligns with the needs of European customers: high safety, predictable lifetime and resilient supply chains.

Safety

  • Inherently stable sodium-ion chemistries that significantly reduce the risk of thermal runaway
  • Safety levels comparable to LTO chemistry
  • Reduced need for complex secondary safety systems at module and pack level

Performance

  • Wide operating temperature range (–40 °C to +60 °C) for indoor and outdoor application.
  • Predictable ageing and cycle-life behaviour, simplifying system design and lifetime estimation.
  • Focus on total cost of ownership instead of pure peak energy density.

Lifetime Performance

  • Our Sofium-Ion technology is designed for Ultra-Long Lifetime performance >20.000 Cycles (100% DoD)
  • Significant advantages in total cost of ownership compared to many LFP and NMC solutions
  • Chemistry enables large-scale deployments without the same raw-material constraints as traditional lithium-ion technologies
  • Particularly attractive for applications where long-term stability and predictable performance are critical

Technology Comparison

AuroraCell Versus NMC

Compared to typical NMC lithium-ion cells, AuroraCell sodium-ion technology offers lower energy density but significantly higher safety and improved sustainability. Our cells rely less on critical and expensive metals, which supports a more secure and ethical supply chain for large-scale energy storage systems.

AuroraCell Versus LFP

Compared to LFP technology, AuroraCell sodium-ion cells deliver similar high safety benefits while offering the advantage of different raw material sourcing. This diversification is attractive for large-scale, cost-sensitive energy storage systems where volume and weight are less critical than safety, lifetime and overall system cost.
