LeydenJar Technologies boosts the energy density of li-ion batteries by replacing the traditional graphite anode with a nanoporous, pure silicon anode. This yields cheaper (-20% costs), greener (-85% CO2 footprint) and higher energy density batteries (+70% as compared to state-of-the-art, 1350Wh/L).


Revolutionizing batteries with greener, cheaper, and higher energy density solutions.
