Scientist I/II - Materials Characterization



San Leandro, CA, USA
Posted on Thursday, July 13, 2023

The Characterization team at Cuberg specializes in studying the chemical and physical properties of battery materials. Our mission is to establish analytical techniques for characterizing key compositional and structural features of cell components to further our understanding of fundamental chemical processes and improve cell performance. We provide innovative problem-solving through high-quality data collection and interpretation. We are looking for an enthusiastic and creative individual to work on projects involving method development of advanced characterization techniques to study battery materials including electrolyte, cathode, anode and separator.


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.
