Very very good article you found there skylion explaining the benefits of vanadium flow batteries over lithium batteries when it comes to energy storage,even though the article is a few years old its even more relevant today than ever,look at the money being pump into research and development into the energy and storage market right now,its huge.Thats what i love about POW they have vanadium flow battery development happening as well as a major vanadium resource,thats a win win
