The Science Behind NaXcell™

At the core of NaXcell™ is advanced sodium-ion battery chemistry that delivers safe, efficient, and scalable energy storage. By replacing lithium with sodium—a far more abundant and less volatile element—our technology avoids the supply chain constraints and thermal risks associated with traditional lithium-ion systems. This innovation enables energy resilience and cost-effectiveness across a wide range of applications.

“Why Sodium-Ion Now — and What’s Next”

​

Sodium-ion batteries function similarly to lithium-ion batteries but use sodium ions (Na+) to carry charge between the electrodes. Sodium is plentiful, easier to source sustainably, and less reactive, making it ideal for energy storage that is safer, greener, and more predictable.

 

Key Advantages:

  • No lithium, cobalt, or nickel required

  • Non-flammable, thermally stable chemistry

  • Wide operating temperature range (-40°C to +60°C)

  • Naturally suited for large-scale and cold-climate use

What Research Tells Us About the Future of Sodium-Ion

​

A 2024 study by Stanford and Princeton researchers shows that sodium-ion batteries can become cost-competitive with lithium-ion by the 2030s — especially if supply chains for lithium and graphite tighten. At NaXcell™, we focus on use cases where sodium-ion already makes economic sense today.

Built for Real-World Conditions

NaXcell™ batteries are powered by cells manufactured by QNAS China, a global leader in commercial sodium-ion cell production. QNAS’ cylindrical cell format offers consistent performance, structural stability, and ease of integration into existing system architectures.

​

  • Cell Type: Cylindrical sodium-ion

  • Energy Density: ~100–120 Wh/kg

  • Cycle Life: 5,000+ full cycles

  • Efficiency: ~93% round-trip

​

Safe to Ship, Safe to Store
Unlike lithium-ion batteries, NaXcell™ sodium-ion cells can be stored and transported at 0 volts, significantly reducing chemical risk.

  • No copper dissolution

  • No risk of thermal runaway

  • Safe for air and sea transport

  • Can be shorted for extended periods without damage

​

This is made possible by the use of aluminum as the negative current collector, which does not react with sodium as copper does with lithium.

Smart storage isn’t just about energy—

it’s about reliability, safety, and economics.

NaXcell™ delivers all three.
