No,. they didn't. read the thing carefully. It had three times the POWER
density, not three times the ENERGY density.
Yes, they *are* talking about 3x energy density in milliamp hours per
gram (as well as discussing charge rates in amps per gram).

think they can charge ÂŁ30 for access to their online articles while

They're even dumber than that actually: have a free pdf file:

.... oh, actually to be fair on the publisher, that's deliberately free:
"Tsinghua University Press (TUP) provides €śJust Accepted€ť as an optional
and free service which allows authors to make their results available to
the research community as soon as possible after acceptance. After a
manuscript has been technically edited and formatted, it will be removed
from the €śJust Accepted€ť Web site and published as an ASAP article."
