Vanadium Redox Flow Batteries . The Future of EV. “The VRFB’s long life, exceeding 20 years, makes it one of the most sustainable and long-lasting ways of storing renewable energy. At the end of the battery’s mechanical life, the vanadium electrolyte can be reused indefinitely.”
In contrast to a lithium-ion battery, which stores all the charge inside the battery cell itself, VRFBs use a circulating electrolyte solution of vanadium pentoxide to store the charge in tanks.”
That means they have a lower energy density compared to Li-ion, but because the tanks can be scaled up to any size, they have the ability to store a lot more total energy. And they have greater depths of discharge.
Vanadium redox flow batteries are also well suited to the harsh conditions of Australia, able to handle high temperatures without the risk of explosion, and will be ideally suited for remote stretches of Australia’s landscape and roadways.
