The biggest advantage of vanadium flow battery - Safety
In recent years, lithium battery safety problems occur frequently, which has attracted social attention. As a rookie in the field of energy storage, the safety advantage of all vanadium flow battery is very prominent.
According to incomplete statistics, over the past three years, more than 30 explosions and fires have occurred in global lithium battery energy storage projects.
On July 30, 2021, a fire broke out in the "Victoria battery" project near Jilang, Australia. Tesla Megapack battery pack with 13 tons of lithium ion battery caught fire. About 150 firefighters are trying to control the spread of the fire to other battery packs at the scene. According to the news previously released by neoen, the project was registered with the Australian energy market operator on July 28. This means that two days after registration, a fire broke out in Tesla's Megapack energy storage unit.
All vanadium flow battery uses the mutual conversion between vanadium ions with different valence states to realize the charge and discharge process by storing and releasing chemical energy. Different from the current mainstream battery of energy storage power station - lithium battery, because the lithium battery adopts non-aqueous electrolyte, while the electrolyte ions of all vanadium flow battery exist in aqueous solution, which greatly reduces the possibility of battery overheating and explosion. The safety performance of the battery makes it stand out in the battery field.
