Safran and Cuberg to collaborate on battery systems for electric aviation

Sept. 26, 2023

PARIS - Safran Electrical & Power in Paris and Cuberg in San Leandro, California announced the two companies plant to combine their technologies to create a high performance propulsive energy storage system for future generations of aircraft. Cuberg, a vertically integrated battery provider, will manufacture and supply rechargeable aviation battery systems based on Cuberg’s lithium metal cells, modules, and packs while Safran Electrical & Power will design and develop global energy storage systems, including high voltage protection components, integration, certification and in-service support.

Cuberg battery systems are built on the configurable Cuberg module, which has been internally validated to achieve a specific energy of 280 Wh/kg and an energy density of 320 Wh/L. This specific energy, Cuberg says, is up to 40% higher than comparable modules based on lithium-ion technology. This improvement provides increased flight range which, in turn, enables new use cases for electric and hybrid aviation. Cuberg modules are purpose-built to manage the mechanical, thermal, and electrical integration of next-generation battery cells.

The Cuberg module incorporates Cuberg’s 20 Ampere-hour lithium metal cell technology. This technology uses a lithium metal anode and proprietary liquid electrolyte to simultaneously solve the interlocking challenges of high-performance cell design and manufacturability.

“We are excited to team with Cuberg as they propose unrivaled disruptive battery cell technologies associated with a best-in-class industrialization process strongly supported by Northvolt. Their unique technology, combined with our expertise in aircraft electrical systems, will enable cutting-edge energy storage systems for future platforms." said Bruno Bellanger, vice president & general manager of Power division, Safran Electrical & Power.

“This partnership with Safran Electrical & Power will help both companies provide certifiable integrated battery systems to aviation customers around the world, and we are thrilled to be working with such an elite and respected provider of aviation products.” said Cuberg CEO and founder Richard Wang. “Cuberg has built the world’s most established high-performance aviation battery systems program, and this agreement is a welcome endorsement of our technology, our people, and our vision for the future of flight.”
