Na-ion (PBA) is a natural fit for low voltage applications.
Key advantages beyond electrochemical performance.
- PFAS-free cells. Compliant with REACH & RoHS.
- Water-based electrode coatings. Eliminates toxic solvents (e.g. NMP), lowering processing cost and easing environmental compliance.
- Aluminium-only electrodes. Eliminates copper foil, simplifying logistics and cutting material cost.
- 0V storage capability. Long-term storage and logistics without maintenance charging.
- Drop-in compatible with Li-ion manufacturing lines.
Commercial models.

Integration partnership. Tailored cell variants for your application, shared roadmap, shared IP.
Common questions.
The P-Series is optimised for high C-rate applications requiring rapid, repeatable power delivery. The E-Series is optimised for long-duration endurance applications with maximum cycle life. Both are built on the same Prussian White cathode active material.
Yes. The P-Series is engineered for drop-in compatibility with existing lead-acid form factors and battery management systems in 12V, 24V and 48V automotive architectures.
No. Altris sodium-ion cells are classified as Non-Dangerous Goods (Class 9 Exempt) and can be stored and shipped at 0 volts.
Built on Altris’ proprietary CAM
Our Prussian White powers both Power and Energy applications.
The P-Series uses the same Prussian White cathode active material as the E-Series – iron and sodium, manufactured in Czechia from European raw materials. One chemistry, two cell formats, every market segment.
