Cuberg’s Next-Gen Battery for Electric Flight Earns U.S. Dept. of Energy Validation

Battery innovator Cuberg announced that its electric aviation battery technology demonstrated an exceptional combination of specific energy, specific power, and cycle life in an independent testing and verification process conducted by Idaho National Laboratory (INL) on behalf of the U.S. Department of Energy. The announcement of this achievement in the performance and maturity of battery technology was featured in key industry trade publications including Aviation Week, eVTOL.com, TransportUP, and Sustainable Skies.


Three key battery performance measures need to be optimized in balance for successful use in aviation: specific energy, which allows for longer flight times and ranges at a given weight; specific power output, which enables greater aircraft weights and payload capacity; and cycle life, which impacts cost of ownership. With testing that included an up to 80% increase in specific energy relative to Lithium-ion cells of comparable high-power output, Cuberg became the first company to successfully combine this level of energy with high power and competitive cycle life under realistic operating conditions. These results represent a major step forward in battery technology for the future of electric mobility.


“Cuberg’s mission is to deliver next-gen batteries to power the rise of electric mobility, and an essential part of our strategy is to achieve independent verification and transparency of our results,” said Richard Wang, co-founder and CEO of Cuberg. “We are gratified to receive this verification by INL of the industry-leading performance and reliability of our technology, and excited to be working with our customers to begin full-scale flight testing in their aircrafts in the next year.”
