Redox Flow Battery

4th Generation RFB Design

The advantage of this RFB is that the power and energy specifications can be scaled independently.

The amount of energy stored is proportional to the volume of electrolyte solution in the storage reservoirs. The power on the other hand is directly proportional to the size of the power stack.

This System achieves and maintains full electrolyte utilization. Other battery systems degrade over time losing the ability to fully charge and discharge. The Vanion Battery will transition from fully charged to fully discharged and back without degradation for an unlimited number of cycles, for more than 25 years.

The Vanion RFB can charge and discharge simultaneously which is ideal for the incorporation of renewables as it will regulate cycle and voltage ensuring a stable flow of electricity when required.

Decoupling the power (kilowatts – kW) and energy (kilowatt hours – kWh) by warehousing the electrolyte in separated storage tanks and not in the power cell of the battery, (like lead acid and lithium-ion), dramatically improves the useful/economic life of the platform as well as removing the risk of overheating (cascading-discharge), which leads to fire and explosion (thermal-runaway), resulting in battery failure and hazardous environmental consequences.

This new system is scalable for grid applications from kilowatt to megawatt and can easily incorporate power generated from diesel gensets and renewables like solar, wind and run-of-river.

A Fully Integrated,
Containerized Energy Storage System.

Safe and Transportable Anywhere


This high energy-density battery with full charge and discharge capability is controlled by a Battery Management System (BMS) capable of response performance in milliseconds, ensuring constant regulated power, making it commercially viable in all areas of electrical demand.
