Robust, long-lasting batteries. No critical raw materials.

We develop sodium-ion battery cells based on Prussian White cathodes.

Why Sodium-Ion Batteries?

At the moment, every modern battery in electric cars, power stations, and home storage systems is lithium-based. This dependence is associated with several problems. We can solve these problems using sodium-based materials:

Lithium Shortages

By the end of this decade, lithium demand will be so high that supply shortages are expected. This could drastically increase the price of lithium.

Abundant Raw Materials

Sodium-ion batteries can use abundant materials that are available everywhere on Earth (and Mars), and lowers the geopolitical problematics associated with batteries.

Low Cost

Cathode and anode account for 60% of the cost of a battery cell. The use of inexpensive active materials in sodium-ion batteries offers the possibility of significantly reducing costs at the cell level.

Energy Density

Sodium-ion batteries have the potential to reach energy densities comparable to entry-level lithium-ion batteries.

Fast Charging

With proper material choice, sodium-ion batteries can potentially achieve high charging capabilities.

Low-Temperature Performance

Sodium-ion batteries can provide excellent low-temperature performance that outperform lithium-ion batteries.

Why Prussian White?

Prussian White is a cathode material for sodium-ion batteries that can achieve the same specific energy (Wh/kg) as lithium iron phosphate (LFP). It does not rely on lithium, cobalt, nickel, copper or vanadium and is made of 100% abundant elements. These have the potential to significantly reduce the cost of battery cells.

Furthermore, it guarantees a stable voltage plateau that delivers the same power regardless of the State of Charge.

However, its energy density (Wh/L) is about 40% lower compared to LFP.
