LeydenJar Technologies

LeydenJar Technologies BV is a spin out venture from Dutch applied research center TNO, LeydenJar is developing pure silicon anodes for use in Li-ion battery cells, improving the energy density up to 1.200 Wh/l and 450 Wh/kg. The pure silicon anodes are based on a proprietary PECVD method to create porous silicon layers directly on top of the copper substrate. The production process is developed to reach cost parity with coating based production, while allowing for 100% silicon content. In 2019 LeydenJar will establish its base plant at the High Tech Campus in Eindhoven, the Netherlands, to demonstrate semi commercial production and to produce silicon anode rolls for testing and first commercial products.
