Adden Energy is a Massachusetts-based startup founded in 2021 by a team of Harvard scientists, including co-founders Li, William Fitzhugh, PhD, and Luhan Ye, PhD. The company focuses on developing solid-state battery technology primarily for electric vehicles (EVs) and advanced applications like drones and robotics.

Their innovative technology features self-healing solid-state separators and a porous lithium metal anode, enabling ultra-fast charging times of as low as three minutes and long lifetimes with over 10,000 charge cycles. Adden Energy's batteries are designed for safety, using non-flammable components, and aim to provide longer driving ranges than gasoline vehicles at a lower cost per kilowatt-hour. The company is committed to making EVs more accessible and practical, addressing key consumer barriers such as charging speed and battery longevity. They plan to scale battery technology from small pouch cells to full-scale vehicle batteries within three to five years, collaborating with research institutions and industry partners to support innovation and market integration.
