Vanadium

When it comes to battery technology, I have only read superior comparison of vanadium over lithium.  But if it is so much better, why is it not in daily use?  It would appear to be more suited for large scale storage rather than for appliances.

When I first invested in lithium companies, it took ages before some become profitable and others are still languishing.

The question now is do I go ahead and start on vanadium miners?

KRC is worth almost next to nothing in my portfolio!
