Anthro Energy broke ground on Tuesday on a factory in Louisville, Kentucky, that can make enough battery materials for more than 300,000 electric vehicles.<\/p>\n

But the facility\u2019s headline output, 25 gigawatt-hours worth of electrolytes, is just part of the story. Anthro\u2019s factory could give solid-state batteries a much needed boost in the U.S.<\/p>\n

Battery manufacturers are scouring the planet for materials that aren\u2019t encumbered by \u201cforeign entity of concern\u201d problems \u2014 in other words, materials that aren\u2019t somehow controlled by Chinese companies. Anthro hopes its new facility, scheduled to start production in 2028, can help fill that need for many U.S. companies.<\/p>\n

\u201cWhen it opens, we\u2019ll be serving domestic, high-spec customers, this emerging ecosystem for battery production where they frankly just needs electrolytes \u2014 a domestic source of China-free supply, FEOC-free supply,\u201d David Mackanic, co-founder and CEO of Anthro Energy, told TechCrunch in an exclusive interview.<\/p>\n

The startup, which raised its first funding round just four years ago, wants its Kentucky factory to become a key node in the emerging U.S. battery supply chain. \u201cWithin a 12-hour drive, you can get to 70% of the battery production facilities in the United States that exist today,\u201d he said.<\/p>\n

To build the factory, Anthro received a $24.9 million award from the Department of Energy under the Bipartisan Infrastructure Law, and another $18.4 million in investment tax credits under the Inflation Reduction Act. Kentucky pitched in another $2.3 million in tax incentives in exchange for creating 110 permanent jobs.<\/p>\n

The Louisville factory will be set up to make a range of electrolytes, though Mackanic said he\u2019d eventually like to see much of the output dedicated to Athro\u2019s own polymer product, Proteus, which is designed to drop into an existing production line with minimal tweaks \u2014 a major reason why the startup can begin production using other company\u2019s formulations. Once customers validate Anthro\u2019s own material, the startup can shift production accordingly. <\/p>\n

There\u2019s every reason to think at least a portion of those customers will make the switch eventually. Proteus is a polymer that promises pave the way to solid- and semi-solid-state batteries, a holy grail of the battery industry. Chinese companies are reportedly looking to start trial production of solid-state batteries in 2027.<\/p>\n

Solid-state batteries promise to solve a range of challenges presented by the lithium-ion batteries commonly used today. Solid-state batteries help boost energy density, and by eliminating flammable electrolytes, they should reduce the risk of fires. Also, because they form a solid barrier between the anode and cathode, they prevent the appearance of dendrites, which are spiky growths that can bridge the two electrodes and cause short circuits.<\/p>\n

But for all their promise, solid-state batteries have so far failed to reach their potential because no one has figured out how to cost-effectively manufacture durable cells at scale.<\/p>\n

Anthro might have a solution to those challenges. In its manufacturing process, Anthro\u2019s electrolyte flows into the cell as a liquid, allowing it to penetrate the anode and cathode, just like today\u2019s liquid electrolytes. Later, it firms up, essentially gluing the two parts of the battery together.<\/p>\n

The result is a cell that, depending on the formulation, is not just stronger \u2014 \u201c10 to 15 times stronger than with a liquid electrolyte,\u201d Mackanic said \u2014 but can be flexible, too. Ultimately, he envisions those qualities paying dividends not just in EVs, but drones and robots as well.<\/p>\n

Plenty of other battery materials companies have failed at this precise moment, when they move from small-scale to larger scale production. But Mackanic is optimistic that the federal funding will help Anthro vault over the valley of death. <\/p>\n

\u201cTo get into big applications, you have to have big production,\u201d he said. \u201cThe Department of Energy award solves a lot of the chicken or the egg problem.\u201d<\/p>\n<\/div>\n
