Hvad er vanadium? Vanadium er det 23. element i det periodiske system og er hovedsageligt brugt som legering i værktøjsindustrien. Derudover er det et metal med en høj elektrisk tæthed som bruges til elektrolytvæske, eksempelvis i et redox flowbatteri. Vanadium bruges netop på grund af dets unikke evne til at tilgå fire forskellige oxidationsniveauer – V2, V3, V4 og V5 …
