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 SnO2 a superior electrode for vanadium redox flow battery?
Jiang QC, Li J, Yang YJ, Ren YJ, Dai L, Gao JY, He ZX (2023) Ultrafine SnO2 in situ modified graphite felt derived from metal–organic framework as a superior electrode for vanadium redox flow battery. Rare Met 42 (4):1214–1226
Is vanadium cheaper than lithium ion?
"At more than three hours' storage, vanadium is cheaper than lithium-ion." Storage time (or capacity) is a function of the amount of stored electrolyte, or the size of the tanks. Since VRFBs are most cost-efficient with size, they're probably going to be very big. That's why you may never see one.
