I can't find the text you found, but I did find this, on the Press page:
QuantumScape Releases Performance Data for its Solid-State Battery
Technology
12/08/2020
...
QuantumScape’s newly-released results, based on testing of single layer
battery cells, show its solid-state separators are capable of working at
very high rates of power ... The tested cells were large-area
single-layer pouch cells in the target commercial form factor with zero
excess lithium on the anode and thick cathodes (>3mAh/cm2), running at
rates of one-hour charge and discharge (1C charge and 1C discharge) at
30 degrees Celsius. These tests demonstrated robust performance of these
single layer pouch cells even at these high rates, resulting in retained
capacity of greater than 80% after 800 cycles (demonstrating high
columbic efficiency of greater than 99.97%).
I hope their press release is genuine and not snake oil.

Iam having a hard time with the QuantumScape story line. If you look closely
at their documentation - e.g. read the really small fine print, buried deep at
the end of their corporate history page, they say they have no prototype for
the solid state battery they “will manufacture”. And that they are still
trying to develop the revolutionary new, battery membrane that will enable all
this to work. When and if they are successful, they need two years to build a
prototype facility to test the design, then another four to five years to
enlarge the plant to actually start producing and selling commercial
quantities.
So 5-7 years away from actually selling anything. IF they can discover the
revolutionary new battery membrane to make all this work.
And They never include these key business metrics when they hype their progress.
Sounds like something akin to the old time snake oil salesmen selling lush
Western farmland out beyond Oklahoma. but turns out they were really talking
about the Sonoran desert.
Am I missing something in their pitch?
