"charges 20 times faster", which is also found in the title, is a statement about power density.
My post was a reply to the post that decried nutty battery companies. I just wanted to point out that 20x power density of lithium ion is something that's actually feasible and available today. It, however, isn't all that useful and if you have to sacrifice even a single percent of energy density for it you're better off with lithium-ion batteries.
