We transform
EV battery waste into value
using cutting-edge technology to create reliable, low-cost "second-life" energy storage systems.
Our values
Integrity
Sustainability
Safety
Early history
We were founded in 2018 to commercialize nearly a decade of research at the University of California, Davis on used battery testing, reassembly, and controls.
Recent progress
Since commissioning our commercial-scale demonstration in 2019, we have established and scaled our battery testing and reassembly operations in Fairfield, CA.
Future goals
By the end of this decade, over 150,000 tons of EV batteries will be retired in the United States alone. We aim to give these batteries a second life.
