Product Outline

VRFB basically consists of cell stack, two independent electrolyte tanks, pumps and pipeline. With the help of the pumps, the electrolyte is circulated between the cell stack and electrolyte tanks. In the electrolyte, vanadium exists four different oxidation states:V2+, V34, V4 + and VSt. A reversible electrochemical reaction of the vanadium ions takes place in both half-cell of the cell stack, allowing electrical energy to be stored or released. The stack determines the power (kW) of the energy storage system, and the electrolyte determines the capacity (kWh) of the energy storage system.
