Sodium-ion solutions where
supply, safety, and storage are non-negotiable.
Validated for -40C cold start, 0V stockpile storage, Class 9 Exempt logistics, and 100% European materials.
Mission-critical requirements
Built for the conditions that break other chemistries.
Five capabilities Altris cells deliver out of the box – without active thermal management, without compromise.
-
01
Energy dense down to -40C.
Retained capacity across arctic, alpine, and continental winter conditions – without active heating.
-
02
Safety.
Best-in-class safety profile under abuse testing – no thermal runaway cascade.
-
03
100% European material origin.
Sovereign supply chain. No dependence on conflict minerals or single-source geographies.
-
04
Non-Dangerous Goods.
Simplified field deployment, no hazmat surcharges, full transport flexibility.
-
05
0V storage capability.
Long-term stockpiling without maintenance charging.

Common questions.
Altris cells are validated against industrial test standards including cold-start, cycle life, and abuse tolerance. Certification programmes for specific defence standards are available through our co-development process.
Yes. Altris sodium-ion cells can be stored at 0 volts with minimal degradation – a critical capability for defence and emergency readiness applications.
