Senior Battery Cell Designer, R&D



San Leandro, CA, USA
Posted on Friday, July 28, 2023

Cuberg builds high-performance energy solutions based on next-generation technology for the world’s most demanding battery applications. Cuberg technology, paired with the manufacturing excellence of parent company Northvolt, will help give rise to a new generation of mobility businesses and decarbonize hard-to-abate segments of the transportation industry.

Cuberg technology uses a lithium metal anode and proprietary liquid electrolyte to simultaneously solve the interlocking challenges of battery performance and manufacturability. While incumbent battery technologies, such as lithium-ion, can be too heavy and low-performing for use in aircraft, Cuberg’s battery cells are lightweight and high-performance. The technology is also compatible with industry standard manufacturing methods, enabling scalability, reliability and traceability across the value chain.

Cuberg and Northvolt believe that complete electrification will require a revolutionary spirit and a practical mind. We won’t just design the world’s best batteries—we will ship them at scale.
