Natron Energy

Natron Energy is an energy storage company that develops sodium ion battery solutions leveraging Prussian Blue electrode materials. Natron’s battery products are based on a unique Prussian Blue chemistry and can integrate into a wide variety of energy storage applications, ranging from critical backup power systems to EV fast charging and behind-the-meter applications.

Natron Energy develops sodium-ion batteries using Prussian Blue chemistry as an alternative to lead-acid and lithium-ion batteries. Natron claims that its battery solution is the first to not be lifetime-limited due to chemical factors. The company’s new cell technology is based on Prussian Blue analog electrodes and a sodium-ion electrolyte that charge and discharge by single-phase reactions within the stability window of the electrolyte. This eliminates the conversion reactions and electrolyte decomposition that limit the lifetime of lead-acid and lithium-ion cells. Natron’s battery technology can be used in mission-critical stationary applications such as data centers, electric forklifts, smart grids and microgrids, and renewable energy support systems.
