IMABATTERY®

Our redox-flow battery technology improves on past iterations and reduces the cost of energy to less than $100/kWh 

without sacrificing performance.

Complex Iron-Chromium Redox Flow Battery Technology

 Researchers at Cougar Creek Technologies have developed redox-flow battery technology with a near-neutral solution for increased performance and safety. Using complex cations formed from ligands, we are able to raise the potential of each compound. Our energy-dense electrolyte solutions are made from industry-grade chemicals and don’t require any catalysts, creating an incredibly stable system. In the redox reaction, an acid is reduced and a proton is lost. Competitors use expensive proton membranes to transfer charge between electrolytes, but IMABATTERY® uses porous separators that allow cations and anions to move between the fluids, reducing proton transfer. This keeps performance high and system costs at a breakthrough low of less than $100/kWh.

Advantages of IMABATTERY®

- Intrinsically safe, aqueous system with no risk of fire

- Near neutral electrochemical reaction

- 25+ years of service life with unlimited cycles

- 0% capacity decay

- Zero negative environment impact at the end of service

- Occupies less space than lithium-ion batteries

- Built-in absorbent cleans up leaked electrolyte solution

IMABATTERY® Technology

Our latest redox-flow battery technology successfully solves the key problems of past models:

IMABATTERY® uses an iron-chrome redox reaction. These materials are earth-abundant, cheap, and easily recycled. Our batteries are able to provide energy storage for the present as well as the future.


A sub-system using Vanadium-containing solutions and a hydrocarbon material as a reductant has been developed to reduce Fe 3+ back to Fe 2+ and to compensate the proton loss due to H2 generation.


IMABATTERY® avoids harmful catalysts that would otherwise contaminate the electrolyte solution. Our organic compound has the same desired effects as a catalyst, extending the battery's overall lifetime without negative impacts.
