Cuberg, a Northvolt subsidiary at the forefront of new technology development in the battery sector, has today published a validation report of its first-generation lithium-metal battery module. The results are a testament to the exceptional performance of Cuberg’s lithium-metal technology and represent the world’s first third-party validation of a lithium-metal battery module.
Designed to fulfil the operating requirements of a fully electric vertical takeoff and landing (eVTOL) aircraft, the lithium-metal module is capable of providing high discharge rates, at low weight, with consistent performance over hundreds of missions.
Featuring 60 lithium-metal 20 Ah pouch cells, the battery module was validated using flight profiles representative of an eVTOL aircraft. As detailed in the report, the module performed 692 cycles before reaching capacity retention of 90% and demonstrated specific energy of 284.8 Wh/kg — performance never before achieved with lithium-metal technology.
The high specific energy of the module translates to increased flight range which, in turn, enables multiple use cases for electric aviation. High specific energy would enable operators to choose between longer cruise times or heavier payloads — both of which expand the opportunities for eVTOL businesses cases.
Shauna McIntyre, CEO Cuberg, comments: “Our mission is to push the boundaries of what’s possible with battery technology. The validation of our first lithium-metal module marks a milestone in our journey towards commercial lithium-metal battery solutions. With a focus on performance, safety and reliability, we’re committed to accelerating the adoption of electrification across new market segments and accelerating the transition to a cleaner future.”
