Nickel-Iron based energy storage system.

The main components of TerraBattery are individual cells made out of the metal nickel and iron. These individual cells are assembled along with other electronics into a plug-and-play battery system for users. It contains no lead, cadmium, or cobalt. Thus, its construction and recycling processes do not pose environmental and health concerns.



Thomas Edison commercialised the nickel-iron battery in the early 1900s as an alternative to lead-acid.

Nickel & Iron

Nickel and iron are naturally-occurring elements that are abundant on earth and easily found in your daily lives. 


We bring back this battery technology, so as the role of renewable energy continues to grow in the future, storing energy can be sustainable, simple, and safe. 


Operate in extreme weather and demanding environments. Wide operational temperature range of -40°C to +45°C. 


Tailor storage capacity and power output to match your specific needs.


Made out of non-toxic and completely recyclable materials, meet your energy demand with minimal environmental impacts. 


Aqueous (water-based) electrolyte thus no instantaneous combustion possible due to temperature increase. Built with adequate passive ventilation to be safe for the environment and for you.

Engineered to last

Long-lasting performance that withstands operational stresses. Energy storage that lasts through the lifespan of your renewable energy source.

Plug and play

Smart design for easy installation and carefree maintenance.

Power smarter and make the world circular.
