Nahhhhhh, Shell Canada disagrees @AGROS

“JT Steenkamp, a Shell Canada engineer has been testing out a new type of battery at Shell Canada's research center in Calgary, using vanadium, usually considered a by-product of oil sands production. What particularly was exciting to Steenkamp was vanadium's unusual properties. “Vanadium is a really special element in that it is able to exist stably in a whole host of valence states,” he says, “so you can use the same electrolyte both in the positive and the negative half-cells of the battery. When you don’t use the same electrolyte, you’re at risk of degrading the battery over time as each half-cell becomes contaminated with the electrolyte from the other.”

This is just the beginning; look long and be strong
