$15M Raised to Develop Electric Vehicle Batteries That Charge in 10 Minutes

Researchers with Harvard University have developed a solid-state battery for electric vehicles that can fully recharge within 10 minutes—and have just received funding to produce a pilot line of them, reports Electrek.

The batteries are made with a lithium metal anode, which has allowed ions to attach to the surface of the silicon particle and not penetrating further, allowing for an even surface and more efficient plating and stripping.

$15 million has now been raised by Adden Energy as part of a Series A round led by At One Ventures to launch a roll-to-roll pilot line production facility for the batteries, and eventually bring the technology to automakers.

Adden Energy has shared that by 2028, it expects its batteries to help EVs achieve parity with internal combustion engines.

“Our investment in this technology is a signal of how important we know this to be, and it’s also our confidence level in Adden Energy’s ability to win market share through competitive unit economics,” said Laurie Menoud, a partner with At One Ventures and Adden Energy board member. “With the added energy density of lithium metal anodes, the cost per kilowatt hour is going to drop by 30%, and that is going to be a significant driver of adoption.”
