Eindhoven, Wednesday, 10 September 2025.
LeydenJar secures €13 million to finalize its Eindhoven facility, aiming to produce 100% silicon anodes that enhance battery energy density by 50% and reduce CO2 emissions by 85%.

LeydenJar’s Breakthrough in Battery Technology

LeydenJar, a deep-tech startup based in Leiden, Netherlands, has successfully secured €13 million in funding to complete its PlantOne facility in Eindhoven. This facility aims to produce 100% pure silicon anodes, significantly enhancing battery energy density by 50% and reducing CO2 emissions by 85% [1][2].

Investment and Industry Impact

The funding round was led by climate-focused investors Extantia and Invest-NL. This investment marks a pivotal moment for LeydenJar as it transitions from lab innovation to full-scale production [1][3]. LeydenJar’s innovative silicon anode technology is set to revolutionize the battery industry by enabling smaller, lighter, and more powerful batteries, which can be used in a wide range of applications, including AI-powered wearables, electric vehicles, and aviation [2][3].

Global Ambitions and Sustainability

LeydenJar’s PlantOne factory, expected to become operational in 2027, will have an annual production capacity of 125,000 square meters of silicon anode material, sufficient to power 5 million smartphone batteries or the entire global demand for earbuds [4][5]. The production process employs a roll-to-roll PECVD machine, which not only enhances efficiency but also aligns with sustainable practices by significantly reducing carbon emissions [5][6].

Strategic Positioning in the Battery Market

The strategic positioning of LeydenJar in the battery market is underscored by its commitment to addressing the challenges faced by traditional battery technologies, particularly the issues of swelling and cracking associated with silicon anodes [6][7]. By achieving over 500 charge-discharge cycles without external pressure, LeydenJar’s technology sets a new benchmark for commercial viability [7].
