E-STONE BATTERIES

We develop nickel-iron batteries and perform research towards iron-air batteries. In our prototypes we combine our easy innovative fabrication method and use our patented iron-electrode formulation.

The cycle life is already proven to be several times longer than lead-acid batteries and the energy density is 2-3 times greater. In future, we aim to replace the nickel for a much cheaper and more sustainable air electrode.

The abundance, direct availability and global utilization of iron makes it ideally suited  as the affordable clean-energy storage material, enabling energy storage for everyone, everywhere. Just take a look around you, from building materials to your body, the world runs on iron!
