Anthro Energy breaks ground on Kentucky plant to supply China-free electrolytes for EVs

Anthro Energy broke ground on a Louisville, Kentucky facility that will generate enough electrolyte material for over 300,000 electric cars, with an initial capacity of 25 GWh. The plant, expected to begin production in 2028, is financed by a $24.9 million Department of Energy grant, $18.4 million in tax credits under the Inflation Reduction Act, and $2.3 million in state incentives, supporting 110 permanent jobs. Mackanic highlighted the site's strategic position, reaching roughly 70 % of U.S. battery factories within a half-day drive, and its role as a China-free source for high-spec customers.

While the factory will initially produce a range of electrolytes, the company hopes to shift much of the output to its proprietary polymer, Proteus, designed for easy integration into existing lines. Proteus aims to enable solid- and semi-solid-state batteries by solidifying after flowing as a liquid, delivering cells up to 15 times stronger than those with conventional liquid electrolytes. Mackanic believes the federal support will help the company overcome the scaling challenges that have stalled solid-state battery commercialization.
