Group14 lands $463M from SK, Porsche, and others to make silicon anodes for EVs Tim De Chant PM PDT · August 20, 2025 Battery materials startup Group14 announced Wednesday it has closed a $463 million funding round to expand its manufacturing footprint, a sign that investors remain confident in the future of electric vehicles.

The startup manufactures silicon anode materials, which significantly boost the storage capacity of lithium-ion batteries. Group14 currently operates three factories, two in the U.S. and one in South Korea.

Despite headlines about softening demand growth for electric vehicles, the global market for lithium-ion batteries remains strong. Over the next decade, its expected to grow more than 15% annually, quintupling in size, according to Precedence Research. And automakers and investors are still in pursuit of companies working on technology that will make EVs more efficient and affordable.

The round was led

Silicon has long been targeted as a potential replacement for graphite, today’s go-to anode material, because it can hold up to 10 times more electrons. But with every charge and discharge, pure silicon anodes have a tendency to crumble as the material expands and contracts, something that graphite is more resistant to.

Startups like Group14 and its competitor Sila have accommodated silicon’s propensity to swell

The material itself can be blended with graphite or replace it entirely. Many companies still opt for the latter because of graphite’s inherent stability. But the more silicon used, the more energy a single cell can store. Group14 says its material can improve energy density
