Quick Takeaways
- LeydenJar silicon anode battery attracts fresh European institutional investment to scale next-generation lithium-ion technology.
- The funding strengthens confidence in commercializing pure silicon anodes for future electric mobility and energy storage.
On January 28, LeydenJar announced an additional EUR 7.8 million equity investment as part of its previously disclosed capital raise, reinforcing investor confidence in the company’s advanced battery materials strategy. The latest funding round was led by APG, acting on behalf of Dutch pension fund ABP, with participation from TNO.
LeydenJar is a Dutch deep-tech company focused on developing what it describes as the world’s first commercially viable 100% pure silicon anode for lithium-ion batteries. Silicon anodes are widely seen as a critical enabler for higher energy density, longer driving range, and improved performance in next-generation electric vehicles.
LeydenJar silicon anode battery technology targets commercial scale
Unlike conventional graphite-based solutions, the LeydenJar silicon anode battery approach aims to significantly increase energy density while remaining compatible with existing lithium-ion manufacturing processes. This positions the technology as a near-term solution rather than a long-horizon laboratory concept.
Key characteristics of the technology include:
Investment supports PlantOne production roadmap
The newly secured capital will support LeydenJar’s transition from development to industrialization. The company’s first commercial production facility, known as PlantOne, is scheduled to start operations in early 2027. This step is expected to mark a major milestone in bringing silicon anode lithium-ion battery technology to market at scale.
ABP, which serves as the pension fund for government and education employees in the Netherlands, continues to expand its exposure to energy transition technologies through this investment. Participation from TNO further underscores the strategic and technological relevance of LeydenJar’s battery innovation.
With the additional EUR 7.8 million investment, LeydenJar strengthens its position within Europe’s battery ecosystem, aligning long-term institutional capital with the growing demand for high-performance lithium-ion batteries in electric mobility and energy storage applications.
