SOLiTHOR will first target the Regional Aviation and Urban Air Mobility market where it can leverage the advantages of our rechargeable solid-state lithium technology.

Current lithium-ion cell technology is not adequate for powering aircraft over long distances. It is volatile and the risk of fire from the flammable electrolyte is a major concern. Lithium-ion batteries are heavy, and powering for take-off and landing is intensive which dramatically reduces flight time.

SOLiTHOR’s rechargeable solid-state lithium batteries is a major advancement in battery technology and will solve the limitations of Li-ion.


Safe with SOLiTHOR

Aircraft design and operations has some of the highest and most stringent requirements of any industry. Considering that aircraft battery systems will most likely operate within a range of between 150 and 500 kWh, inherent safety and being lightweight is crucial to the success of our technology.

An inherently safe nano-SCE solid electrolyte, combined with thermally stable cells ensures that SOLiTHOR’s technology meets these rigorous targets.

We are targeting regional jets with a journey time of up to 5 hours.


SOLiTHOR’s Solutions to Aviation Requirements

  • High-performance needs - Li-metal anode and pouch cell design    
  • Enhanced safety - intrinsically safe solid electrolyte, thermally stable, allows for denser packs
  • Optimal default working temperature range - easier battery thermal management systems (BTMS)
  • Cost-competitive cells - €/kWh liquid-to-solid based manufacturing for solid electrolyte integration
  • Sustainable production process - lower temperature requirements compared to other solid-state batteries

It is highly likely that SOLiTHOR's cells will be deployed into regional aircraft 
within the next 3 to 5 years.
