About LeydenJar
Developer of silicon anode rolls designed to generate more energy density in Li-ion battery cells. The company's silicon anodes contain capacity compared to graphite anodes and remain mechanically stable, and their production is based on a roll-to-roll plasma deposition process that has the potential to be applied in existing battery plants, enabling organizations to store energy at their capacity.
