Any info about energy density?
According to Wikipedia:
Looks like power to weight it much higher, while energy per volume and energy per mass is comparable to existing lithium ion batteries.
No, the energy to volume is much less.
See, that's what I thought, but the wiki article seems to disagree.
Or am I just misreading something?
