What about long-term demand of each though TJ? Do you know whether those proportions will adjust much in the future or stay the same or not sure? Is there a main driver (use) for graphite? I know it has lots of uses but not sure of whether there is any key drivers in particular. Vanadium I think is something like 80%+ used as a steel additive (ferrovanadium). So in light of the coming VRF battery boom, could it significantly increase the size of the vanadium market by comparison? I suppose it all depends on how much growth there is in VRF batteries vs li-ion etc and how much grsphite is in VRF batteries? Not much I dont think compared other existing battery types...
