There are nano-carbon anode battery experiments from 2-3 years ago that
claimed just that kind of charging density. Could they have gotten
that to actual into production? The word out here is that the Tesla
plant is in the process of moving to the next generation of battery
production.

"But the team is making extraordinary claims about charging, saying the
Mark Zero is capable of blast-charging from 0 to 80 percent of its full
capacity in 4 minutes and 40 seconds. The battery is built by Desten
Group, Limited <http://www.desten.com/>, a Chinese/German operation
based in Hong Kong.
Desten is cagey with details about its batteries, but claims
"exceptionally high charge rates, 10C or higher," as well as power
density in excess of 1600 watts per kilogram. The company says its cells
can be fast charged and discharged 5,000 times before they drop to a
capacity of 80 percent, suggesting excellent longevity particularly if
the cars are charged slowly overnight most of the time."
Definitely not a mistake... who knows whether or not they can actually
do it, but there appears to be a few different companies claiming
they're making batteries that can handle 10C charge rates. I think
they're just using the battery manufacturer's charging claims, and not
actually expecting to be able to charge a real car that fast.

I don't think it was a matter of misinterpretation, there are lots
of different websites saying "under five minutes"... they can't all
be making that mistake.
I suppose it could be something like it's possible to charge these
mystery batteries that fast, but it isn't actually going to happen
in a real car.
