On paper this looks great however I'd be weary of most new battery tech. By their own admission they only produced a small battery and make no mention of the costs of doing so beyond "inexpensive electrode". Theres a reason we're still on Lithium-Ion Despite all the other proposed alternatives. Same with the polymer coating for 200k cycles that is mentioned as being expensive to produce. The tech will get there eventually I just don't think eventually will be within the next few years.
