Cuberg is an energy startup company developing a next-generation battery technology based on a non-flammable liquid electrolyte formulation and a lithium metal anode. These cells deliver a step-change improvement in energy density and safety compared to the best lithium-ion batteries in the world today. The technology has already been demonstrated and validated in thousands of commercial-scale prototypes, and the products are undergoing manufacturing scale-up to supply early drone, electric plane, and air taxi customers.

Cuberg has secured over $8M in funding from private investments and grants, including from: Boeing HorizonX Ventures, the California Energy Commission, the Department of Energy, the National Science Foundation, and the U.S. Army. The company spun out of the materials science department at Stanford in 2016 and was initially supported by the TomKat Center for Sustainable Energy at Stanford. Cuberg graduated from the prestigious Cyclotron Road entrepreneurial fellowship program at Lawrence Berkeley National Laboratory in 2018. We have a close-knit team, an informal and collaborative working style, impactful technology, and exciting commercial progress. Join us as we take this to the next level!
