Anthro Energy breaks ground on factory that could pave the road to solid-state batteries
By Pradhyuman,
Battery materials startup Anthro Energy began construction on a factory in Louisville, Kentucky, on August 18, 2026. The facility has a planned output of 25 gigawatt-hours of electrolytes, which is enough for more than 300,000 electric vehicles. The company plans to start production in 2028.
David Mackanic, co-founder and CEO of Anthro Energy, told TechCrunch that the factory will supply domestic customers with materials free from Chinese control. To fund the project, Anthro Energy received a $24.9 million federal grant and $18.4 million in federal tax credits. Kentucky also provided $2.3 million in tax incentives, which require the company to create 110 jobs.
The factory will make several electrolytes, such as a polymer called Proteus. Mackanic said Proteus flows into a cell as a liquid and later solidifies, which makes the battery 10 to 15 times stronger than cells with liquid electrolytes.
