Leydenjar Technologies has raised 22 million euros to further its battery technology and scale up its production facility. The Leiden-headquartered startup running a pilot plant in Eindhoven has cooked up a nanotextured silicon anode that boosts the energy density of lithium-ion batteries up to 70 percent. Leydenjar is currently developing manufacturing equipment that will allow mass production of the anode material.

Technologically, the TNO spinout’s current main priority is increasing battery lifetime. Another crucial next step will be to upscale the Eindhoven plant to demonstrate cost-effective production on a large scale. As a result of the investment, Leyenjar expects to grow from 25 employees to at least 70 FTEs within the next year and a half.

The series-A capital injection is provided by Catalus Capital, Yard Energy, Invest-NL, ING Sustainable Investments and Somerset Capital Partners. Existing investors, including BOM and Doen Participations, also partake in this financing round. Leydenjar received an additional 5-million-euro subsidy from the Netherlands Enterprise Agency (RVO).
