LeydenJar Technologies develops a 100% Silicon anode that boosts the energy density of Li-ion batteries for application in high-tech niche applications 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.
