Are vanadium redox flow batteries the future?
Called a vanadium redox flow battery (VRFB), it's cheaper, safer and longer-lasting than lithium-ion cells. Here's why they may be a big part of the future — and why you may never see one. In the 1970s, during an era of energy price shocks, NASA began designing a new type of liquid battery.
Is vanadium a viable alternative for energy storage?
China is the world's biggest consumer. Its weak property sector has contributed to the mineral's price weakness.
