Flow Battery Technology

Our Iron Salt Battery is based on advanced flow battery technology, which fundamentally differs from conventional storage technologies. It allows for optimal storage of green energy, ensuring availability both day and night.

The advantages of the Iron Salt Battery are:

Economical Cost-effective provision of long-duration storage

Durability More than 10,000 charging cycles without loss of storage capacity

Safe Storage medium consists of non-flammable components

Flexibility Power and capacity can be scaled independently

Environmentally friendly Without rare or conflict-related raw materials and featuring recyclable battery technology

Function And Design Of A Flow Battery

Energy storages based on flow battery technology are fundamentally different from conventional batteries such as lithium ion.

A flow battery consists of tanks, a pump system and battery cells, also known as a battery stack. The tanks contain a liquid electrolyte solution that serves as a storage medium. The electrolyte is pumped through the battery cells to charge and discharge the battery, binding electrons.

Electrolyte The storage medium is a liquid electrolyte. This is located in separate tanks and can take on different levels of oxidation through an redox process, thereby storing energy.

Battery Stack The electrolyte flows through the battery cells in two circuits. If electrical energy is stored, the electrolyte is reduced in the negative half-cell and oxidized in the positive half-cell. When discharging, this process is reversed.

Pumps A pump system directs the electrolyte into and through the battery cells. This means that all the electrolyte does not have to be retained in the cells. This allows capacity and power to be decoupled. The pumping system is only activated when it is necessary.

Decoupling Of Power And Capacity

In flow batteries, the electrolyte is pumped through the battery cells for charging and discharging and acts as the energy storage medium. The amount of electrolyte determines the capacity, while the number of battery cells determines the power. In this way, the power and capacity of a flow battery can be scaled independently of each other.
