Leydenjar secures €23M funding to scale up silicon anode production

Silicon anode manufacturer Leydenjar has raised 13 million euros in equity financing, alongside 10 million euros in customer funding from a major US consumer electronics company. The combined 23 million will accelerate the completion of the firm’s Plantone production facility in Eindhoven and kick off full-scale operations by 2027.

Leydenjar’s proprietary silicon anodes – branded Silyte – promise a 50 percent increase in energy density, sub-12-minute charging and an 85 percent reduction in CO₂ emissions. Plantone will deploy custom PECVD machinery to produce 125,000 square meters of silicon anode material annually, enough for 5 million smartphone batteries.

“This funding marks a pivotal moment for Leydenjar,” says CEO and co-founder Christian Rood. “We’re now moving from breakthrough lab innovation to full-scale production. Our technology is already integrated into the roadmaps of some of the world’s most ambitious product developers and with Plantone, we’ll be ready to deliver at scale.”
