Wedoany.com Report on Feb 9th, Dutch battery technology company LeydenJar recently announced securing €7.8 million in new equity investment, bringing its total funding to €43 million. This capital will primarily be used to complete the construction of its first production plant in Eindhoven, laying the foundation for the large-scale mass production of silicon anode batteries by 2027.
This round of financing was led by the Dutch pension fund ABP, with participation from the Netherlands Organization for Applied Scientific Research (TNO). Investment bank Stifel acted as the financial advisor. Florent Roulet, Managing Director of Stifel's Technology Investment Banking, stated: "LeydenJar's technology enables faster charging, higher energy density, and significantly lower CO2 emissions, offering more compact and efficient batteries for applications in consumer electronics, electric mobility, and aviation."
LeydenJar's pure silicon anode technology can increase lithium-ion battery capacity by 50% while reducing CO2 emissions by up to 85%. The company has launched its Silyte™ silicon-based anode product. According to test data from February 2025, batteries using this technology can maintain 80% capacity after 500 charge-discharge cycles without external pressure, and 70% capacity after 700 cycles.
CEO Christian Rood noted that ABP's investment reflects recognition of the company's technology. This €43 million funding comprises equity, customer funds, government grants, and loans. Last year, the company completed a €23 million financing round, with €13 million in equity used for factory construction and €10 million from customer funds.
Regarding market expansion, LeydenJar established a sales and business development office in Richmond, Virginia, earlier this year, officially entering the U.S. market. In October 2025, the company formed a strategic partnership with Great Power. The two parties will combine their respective technological strengths in silicon anode materials and end-side new energy solutions to jointly develop high-energy-density consumer-grade batteries, providing energy support for AI edge devices.
By increasing energy density, LeydenJar's silicon anode technology has the potential to break through the size and weight limitations of traditional batteries. The company expects this technology to bring new development opportunities to various fields, including electric vehicles, electric aviation, and smart wearable devices.
