Harvard University's Office of Technology Development recently announced it has granted a technology license to Adden Energy, which is working on a lithium-metal battery that charges in minutes.
Adden is developing solid-state battery systems for use in electric vehicles (EVs), which will likely at some point include construction equipment. The startup recently closed a seed funding round of $5.15 million led by Primavera Capital Group.
According to Harvard, the license will help bring EVs to mass market through the commercial deployment of lithium-metal batteries, used in electronics and EVs.
Harvard reports that Adden aims to scale the battery up to a palm-sized pouch cell, and then upward toward a full-scale vehicle battery in the next three to five years.
“If you want to electrify vehicles, a solid-state battery is the way to go,” said Xin Li, who helped develop the battery technology and is a scientific advisor to Adden Energy. “We set out to commercialize this technology because we do see our technology as unique compared to other solid-state batteries. We have achieved in the lab 5,000 to 10,000 charge cycles in a battery’s lifetime, compared with 2,000 to 3,000 charging cycles for even the best in class now, and we don’t see any fundamental limit to scaling up our battery technology. That could be a game changer.”
The technology, which was developed at Harvard, includes core innovations in solid-state battery design and electrolyte production methods.
