8 August 2024 – Prof. Zhang Huamin, Chief Researcher at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, announced a significant forecast in the energy storage sector. He predicts that in the next 5 to 10 years, the installed capacity of vanadium flow batteries could exceed that of lithium-ion batteries.
Battery storage systems become increasingly more important to fulfil large demands in peaks of energy consumption due to the increasing supply of intermittent renewable energy. The vanadium redox flow battery systems are attracting attention because of scalability and robustness of these systems make them highly promising.
Unlike lithium-ion batteries, Vanadium flow batteries store energy in a non-flammable electrolyte solution, which does not degrade with cycling, offering superior economic and safety benefits. Prof. Zhang highlighted that the practical large-scale energy storage technologies include physical and electrochemical storage.
Exposure of the polymeric membrane to the highly oxidative and acidic environment of the vanadium electrolyte can result in membrane deterioration. Furthermore, poor membrane selectivity towards vanadium permeability can lead to faster discharge times of the battery. These areas seek room for improvement to increase battery lifetime.
In numerous energy storage technology, vanadium redox flow batteries (VRFBs) are widely concerned by all around the world with their advantages of long service life, capacity and power independent design [9, 10].
