LeydenJar Technologies is a spin out venture from Dutch technology institute ECN, developing a 100% Silicon anode that boosts the energy density of Li-ion batteries for application in electric vehicles, consumer electronics, and stationary energy storage. Our technology is based on a proprietary linear MW PECVD proces that is unique in its direct depositioning of silicon on copper foil, rather than existing capital intensive coating processes. PECVD is a mature manufacturing process currently applied in the semiconductor and PV industries.
