Get to know LeydenJar
Modern society needs electric vehicles with longer driving ranges and shorter charging times, smartphones, power tools, and wearables with increased functionality and exceptional battery life, and new and improved technologies to tackle climate change.
LeydenJar Technologies holds the key to this energy-fueled future by enabling the world’s most powerful batteries with radical silicon anodes. With incredibly high energy density, lightning-fast charging, and a low environmental footprint, LeydenJar’s anodes are truly indispensable. The secret lies in ultra-thin, pure silicon battery anodes that enable a lower CO2 footprint with significant cost savings.
Imagine a world where all vehicles are electric and can be charged to full capacity in less than 10 minutes. A world where electric airplanes replace those that run on fuel, and smartphone technologies increase exponentially. This is the world that LeydenJar has been envisioning since its’ founding in 2016.
LeydenJar has raised €40M in venture capital and employs over 70 of the world’s brightest scientists, engineers, and innovators.
Development of LeydenJar
Christian Rood and Gabriel de Scheemaker founded LeydenJar in 2016. They recognized the great value that the silane PECVD process could have for the battery industry.
Proof of Concept
Realization of the first tangible proof of concept. A demonstrated proof in pouch cell format was delivered in cooperation with external scientists and in university R&D-labs. This enabled early stage growth.
World Record Energy Density
LeydenJar demonstrated the highest energy density in the market of 1350Wh/L. Meanwhile, roll-to-roll manufacturability was developed in the GEN2 production tool. These results gained significant market attention, valuable for next steps to market entry.
€22m Series A
Demonstrated high energy density and roll-to-roll production technology gained attention from investors, which resulted of closing a €22m Series A. The final step to first market entry was taken and the organization grew and developed first applications.
Opening Plant One
LeydenJar will open a 100MWh anode foil production facility in 2026: the LeydenJar Plant One. Construction is scheduled for 2023-2024, production in 2025-2026.

Few people can say that they made it possible for airplanes to fly on electricity instead of fuel. Or that they have beaten Tesla’s batteries. Or that they built the foundation for phones that never die.
Can we? We sure think so. Maybe not today, maybe not tomorrow, but we’re close. We strive for a bright, energy-filled future—one step at a time, with big ambitions in mind.
How do we do this? The answer lies not – as one might expect – in our amazing technology. No. It is found in something more complex and unique: our team, culture, and DNA.
What defines LeydenJar’s culture? We’ve captured it in 5 core values. These core values describe what we feel, think, and strive for.
