TerraBattery
A nickel-iron based energy storage system. The nickel-iron chemistry is proven to be robust and safe leading to affordable, long-lasting battery cells with minimum environmental impact. This chemistry is ideal for energy storage in combination with renewable energy sources with daily complete cycling at varying weather conditions.
History
Thomas Edison commercialised the nickel-iron battery in the early 1900s as an alternative to lead-acid. The original batteries from the factory are still being used by people around the world.
Future-proof
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.
Features
Extremely long life
- Design lifetime is 40 years
- Service life of 20 years with daily completely cycling for renewable integration
Inherently safe
- Aqueous (water-based) electrolyte
- Non-flammable and non-explosive
- Electrodes do not contain toxic or rare metals, like lead (Pb), Cadmium (Cd), or Cobalt (Co)
- The chemistry can handle continuous overcharging without experiencing thermal runaway
Robust operation
- Operating temperature ranges from -40°C to +45°C
- Able to withstand deep discharging and overcharging with no permanent damage to cell capacity
Environmentally friendly
- Electrodes are composed of nickel (nickel oxide hydroxide) and magnetite (iron oxide), which are abundantly available in nature
- 100% recycling metal compounds is possible due to the absence of alloy
