Even if we get this high energy density, I'm skeptical about its utility/impact. Right now we are barely able to mine enough lithium for our current batteries, which are used for phones and a few (percent-wise) EVs. As far as I know, and please correct me, we need to increase production by at least 8x for 5-10 rare earth elements in order for everyone to use EVs. Where are these extra rare minerals going to come from?
