Safran is to develop an electrical storage system (ESS) for aviation alongside Cuberg, a subsidiary of Swedish battery maker Northvolt.
Designed to equip future hybrid- and full-electric aircraft, the ESS will combine Cuberg’s rechargeable lithium-ion cells, modules and packs, with a Safran Electrical & Power-developed high-voltage protection system. The French firm will also provide integration and certification expertise, alongside in-service support.
Cuberg’s module design yields improve specific energy and energy density from its liquid electrolyte and lithium metal pouch cells, the company says.
In May, it announced a new programme “dedicated to developing high-performance battery systems that will enable safe, sustainable electric flight”. Deliveries to select customers were due to take place this year.
Northvolt acquired the California-based firm in March 2021.
