Every satellite’s heart is a battery system

providing energy to the satellite when it is in Earth's shadow

The problem

Three key problems

of established space batteries

TOO HEAVY

Current space battery systems are nearly twice as heavy as automotive batteries with the same energy capacity.

HIGH PRICE

Established space batteries are magnitudes more expensive than automotive batteries.

SLOW INNOVATION

Traditional space development programs take many years, leading to outdated tech in space.


In the last 15 years, automotive battery technology has advanced rapidly and is now significantly more performant than established space battery technology.

The solution

Qualifying higher automotive performance for space applications

We are transforming automotive battery cells into space-grade battery systems.

Our approach

Pushing the boundaries of space batteries

TRANSFORMING AUTOMOTIVE BATTERY CELLS INTO SPACE-GRADE BATTERY SYSTEMS

Automotive technology has significantly better performance and lower prices. We qualify it for space by using comprehensive aerospace certification experience.

FUTURE-READY BY USING THE AUTOMOTIVE-STANDARD CELL FORMAT

Our modular & chemistry-independant battery system technology builds upon the industry-standard 21700 cylindrical cell format, enabling fast upgrades to even better future battery cell chemistries.

RAPID DEVELOPMENT LOOPS VIA VERTICAL INTEGRATION

Cell selection, battery system development (mechanical, electral, thermal), production and testing all in-house. Optimized to keep and extend our competitive advantage.

30,000 battery cycles in 5 years

In lower earth orbit (LEO), a satellite circles earth approx. 16 times per day

- that corresponds to 30,000 battery cycles in 5 years.
