Customer ServiceDespite 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.
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.
Vanadium flow batteries “have by far the longest lifetimes” of all batteries and are able to perform over 20,000 charge-and-discharge cycles—equivalent to operating for 15–25 years—with minimal performance decline, said Hope Wikoff, an analyst with the US National Renewable Energy Laboratory.
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.
The Chinese government views the vanadium battery as an alternative to more hazardous storage batteries, such as ternary lithium batteries, due to safety concerns. In June, China’s national energy administration banned the use of ternary lithium batteries and sodium-sulphur batteries for energy storage because of safety issues.
At the end of the battery’s 25+ year lifespan, the vanadium electrolyte can be reused in another battery. It might only need to be rebalanced to recover any minor capacity loss over that time. For example, VRFB manufacturer CellCube reported a ~1% capacity loss for a VRFB that had been operating for 10 years.
