Discovery and invention: How the vanadium flow battery story began

Recognised as one of the original inventors of the vanadium redox flow battery (VRFB) and holder of more than 30 patents relating to the technology. We spoke to her about how some of those original discoveries came about — and why it''s been a long road for VRFBs from lab to mainstream deployment ever since.

Vanadium redox flow batteries can provide cheap, large-scale grid

Called a vanadium redox flow battery (VRFB), it''s cheaper, safer and longer-lasting than lithium-ion cells. Here''s why they may be a big part of the future — and why you may never see one.

6 FAQs about [Comoros vrfb batteries]

What are the disadvantages of a VRFB battery?

VRFBs' main disadvantages compared to other types of battery: toxicity of vanadium (V) compounds. Schematic of vanadium redox flow battery. Solutions of Vanadium sulfates in four different oxidation states of vanadium. Different types of graphite flow fields are used in vanadium flow batteries.

What is a VRFB battery?

The VRFB was first developed in the 1980s and has been commercialised in the past 10 years . The VRFB is more flexible in capacity expansion and design compared with lithium-ion and lead–acid batteries by increasing the volume of electrolytes and the electrode size.

Can a VRFB battery be completely discharged?

Unlike lithium-ion batteries, VRFB can be completely discharged. Professor Skyllas-Kazacos with Dr Menictas and Professor Jens Tübke (far left), in 2018 at a 2MW/20MWh VRFB site at Fraunhofer ICT in Germany. (Supplied: Maria Skyllas-Kazacos) They can store energy for long periods with no ill effects.

Can a battery management system control a VRFB?

Their results showed a peak power of 8.9 kW with a stack specific power of 77 W/kg and a maximum current density of 665 mA/cm 2. Recently, Trovò have used this test facility to develop a battery management system (BMS) as a valuable tool for controlling and testing a VRFB.

How much energy does a VRFB use?

The specific energy is low compared to other rechargeable battery types (e.g., lead–acid, 30–40 Wh/kg (108–144 kJ/kg); and lithium ion, 80–200 Wh/kg (288–720 kJ/kg)). [citation needed] VRFBs' large potential capacity may be best-suited to buffer the irregular output of utility-scale wind and solar systems.

Are VRFB batteries better than lithium-ion batteries?

Nevertheless, compared to lithium-ion batteries, VRFBs have lower energy density, lower round-trip efficiency, higher toxicity of vanadium oxides and thermal precipitation within the electrolyte , .
