Technology: How Flow Batteries Work

A flow battery is a type of rechargeable battery where the battery stacks circulate two chemical components dissolved in liquid electrolytes contained within the system. The two electrolytes are separated by a membrane within the stack and ion exchange across this membrane creates the flow of electric current while both liquids circulate in their own respective space. The maximum power, in kilowatts, of any flow battery is determined by the number of stacks in the power unit as voltage is built up with more stacks. The amount of energy any flow battery, in kilowatt hours, can deliver is determined by the volume of the tanks. Larger tanks lead to longer duration.

Why ViZn Energy is Revolutionary

ViZn Energy’s core technology, chemistry and robust packaging is the result of more than 8 years of engineering and R&D into the most promising energy storage technology available. Our value lies in our ability to simultaneously deliver high-power and long-duration energy services. (Most battery technologies can only excel at one aspect.) The ViZn battery achieves this unique performance blend by utilizing a hybrid flow battery in which alkaline electrochemical components are dissolved in the electrolyte.

Counter to nearly every commercially available energy storage solution, our systems run on a safe chemistry that is non-toxic, non-flammable, and non-explosive. The electrolytes used in the ViZn system are food grade and found in abundance at commodity prices. ViZn’s products deliver unmatched level of performance without sacrificing safety.

The Fundamental Benefits

Energy storage is the enabling technology for the modern electric grid. ViZn Energy storage systems are the safest and most robust solutions under all operating conditions. Our systems can tolerate extreme high-temperature environments and deliver under intense duty cycling across the full state of charge.
