6 FAQs about [Proportion of all-vanadium liquid flow batteries in new energy storage]

What is a vanadium flow battery?

The vanadium flow battery (VFB) as one kind of energy storage technique that has enormous impact on the stabilization and smooth output of renewable energy. Key materials like membranes, electrode, and electrolytes will finally determine the performance of VFBs.

How can vanadium battery capacity be expanded?

The capacity of a vanadium battery can be increased by adding more vanadium electrolytes. This makes it safer for large-scale installation. Given these advantages, the Chinese government sees the vanadium battery as an alternative to other, more hazardous storage batteries.

Are vanadium batteries better than lithium batteries?

Despite the growth, vanadium batteries still represent a much smaller proportion of energy storage compared to lithium batteries, which accounted for 89.6% of the total installed capacity in 2021 according to research by the China Energy Storage Alliance.

Will vanadium battery capacity increase in 2023?

According to a vanadium battery whitepaper published by independent research institute EVTank, vanadium battery storage capacity is forecast to double in 2023 from an estimated capacity of 0.73GW. The capacity will further increase to 24GW by 2030.

What is the cost of a vanadium battery?

The cost of a vanadium battery, when calculated for the whole life cycle, is 300-400 yuan per kWh according to a vanadium trader source. This is lower than the cost of a lithium battery, which is approximately 500 yuan per kWh.

Can vanadium redox flow batteries combust?

Unlike lithium batteries, which can spontaneously ignite or explode, vanadium redox flow batteries are prevented from igniting or exploding by their water-based electrolytes. Vanadium’s ability to exist in a solution in four different oxidation states allows for a battery with a single electroactive element.
