LeydenJar, a Dutch
deeptech company, has raised €23 million to scale its technology
into full production at its Eindhoven facility, PlantOne.
The round includes €13
million in equity financing, led by Extantia and Invest-NL, to complete the
final phase of PlantOne’s construction and begin operations in 2027. In
addition, LeydenJar secured €10 million in customer funding from a leading
US-based consumer electronics company to support the development and
installation of key production equipment.
LeydenJar is developing
Silyte™, the energy-dense pure silicon anode for lithium-ion batteries. Its 100
per cent silicon anodes are ultra-thin, fast-charging, and structurally stable
thanks to a unique porous columnar design, while also cutting CO₂ emissions.
The technology increases
energy density by up to 50 per cent, enables charging within minutes, and
delivers reliable performance across hundreds of cycles.
According to Christian Rood, CEO and co-founder of LeydenJar, the funding represents a significant
milestone for the company:
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.
The
company is investing in expanding its commercial organisation and scaling
operational infrastructure to support rising customer demand and prepare for
full industrial deployment.
