About us
Adden Energy’s dynamically-stable battery will render internal combustion obsolete and usher in a world of battery-powered robotic and other AI-driven mobility applications. Our team spent nearly a decade at Harvard perfecting the science underlying dynamic stability before founding Adden Energy. That decision to focus on hard science first is now paying dividends. Our batteries are the highest performing cells in the world. Even more importantly, the ease of manufacturing dynamically-stable batteries has allowed us to continue to scale with unparalleled speed.
Join us as we achieve EV parity with the combustion engine!
