Here’s how our vanadium flow batteries work. The fundamentals of VFB technology are not new, having been first developed in the late 1980s. In contrast to lithium-ion batteries which store electrochemical energy in solid forms of lithium, flow batteries use a liquid electrolyte instead, stored in large tanks.
There are even 4 MWh containerised flow batteries installed in various locations where the storage of renewable-derived energy needs a buffer to smooth out the power flow. The neat thing about vanadium flow batteries is centred around the versatility of vanadium itself.
Vanadium redox flow batteries (VRFBs) represent a revolutionary step forward in energy storage technology. Offering unmatched durability, scalability, and safety, these batteries are a key solution for renewable energy integration and long-duration energy storage. VRFBs are a type of rechargeable battery that stores energy in liquid electrolytes.
Vanadium flow batteries are gaining attention in the media, various industries, and even the general public for the many benefits over lithium-ion batteries. Those benefits include longer life, very little degradation of performance over time, and a much wider operating temperature range. All of which significantly reduces the cost of ownership.
Other useful properties of vanadium flow batteries are their fast response to changing loads and their overload capacities. They can achieve a response time of under half a millisecond for a 100% load change, and allow overloads of as much as 400% for 10 seconds. Response time is limited mostly by the electrical equipment.
A vanadium / cerium flow battery has also been proposed . VRBs achieve a specific energy of about 20 Wh/kg (72 kJ/kg) of electrolyte. Precipitation inhibitors can increase the density to about 35 Wh/kg (126 kJ/kg), with higher densities possible by controlling the electrolyte temperature.
