LeydenJar Technologies, founded in 2016 and headquartered in Leiden, Netherlands, is a deep-tech company developing 100% pure silicon anodes for lithium-ion batteries. The company applies semiconductor thin-film technology and plasma deposition processes to create its proprietary Silyte™ anode material, which delivers up to 50% higher energy density compared to conventional graphite anodes.
The company's technology targets applications across consumer electronics, wearables, electric vehicles, and broader automotive sectors. Its production process achieves up to an 85% reduction in CO2 emissions compared to natural and synthetic graphite production.
LeydenJar employs approximately 90 people representing 21 nationalities across sites in Leiden, Eindhoven, Virginia (USA), and Taiwan. The company is in a phase of rapid scaling as it works to commercialize its silicon anode technology.
