Harvard engineers develop solid-state battery that lasts 20 years, charges in 3 minutes

Harvard’s Office of Technology Development has granted an exclusive technology license to Adden Energy, Inc., a startup developing innovative solid-state battery systems for use in future electric vehicles that would fully charge in minutes. Adden Energy has closed a seed round with $5.15M in funding led by Primavera Capital Group, with participation by Rhapsody Venture Partners and MassVentures.

The license and the venture funding will enable the startup to scale Harvard’s laboratory prototype toward commercial deployment of a solid-state lithium-metal battery that may provide reliable and fast charging for future EVs to help bring them into the mass market.
