Coulomb Technology is developing and will manufacture novel battery cells for energy storage, backup power, and mobility. These batteries are based on zinc, manganese dioxide, and seawater. They are safer, utilize abundant materials, are faster charging, and are half the price of the incumbent lithium batteries. Coulomb cells include a unique 3D-electroplated anode that reduces dendrites and corrosion and works in low PH regimes. Coulomb Technology is part of the 2024 Innovation Crossroads cohort.
