Anthro Energy has begun construction on a manufacturing facility in Louisville, Kentucky, designed to produce electrolytes for solid-state battery production, with output scaling to materials for over 300,000 electric vehicles annually upon opening in 2028. The project receives $24.9 million from the Department of Energy under the Bipartisan Infrastructure Law, $18.4 million in federal tax credits under the Inflation Reduction Act, and $2.3 million in Kentucky state incentives. The venture specifically targets providing battery components from sources independent of Chinese manufacturing or control—a priority for U.S. battery makers seeking domestic supply chains.

Anthro's manufacturing approach introduces electrolyte as a liquid that hardens in place, creating battery cells substantially stronger than conventional designs while eliminating combustion risks and preventing internal short circuits. The company aims initially to serve multiple battery manufacturers with various formulations before transitioning production toward its own proprietary polymer product, designed to integrate into existing production systems. The facility addresses a critical barrier that has prevented solid-state batteries from reaching commercial viability: the lack of cost-effective manufacturing methods capable of producing batteries at industrial scale.
