Adden Energy

Adden Energy is an advanced battery technology company pioneering next-generation solid-state lithium-metal batteries developed by Harvard scientists with the potential to render combustion engines obsolete. Anchored by expansive patent families, Adden Energy’s breakthroughs enable super-fast charging, exceptional safety, a million-mile lifetime, and a driving range that surpasses that of a gas tank. The technology is the result of nearly a decade of foundational research at Harvard, where academic freedom was essential to getting the science right before company formation. That deliberate approach now allows Adden Energy to move rapidly toward commercialization, supported by the National Science Foundation, the Commonwealth of Massachusetts, leading venture capital firms, and partnerships with multiple global automakers.
