I think part of the confusion comes from the paper doing all of its energy and power comparisons to the mass of pure lithium in the battery- that leads to a lot of numbers being 10-15 times what they should be. Reading the paper is kind of confusing because of it. They also have a couple things that appear to be switched up and finally it doesn't help when they say things like this:
>Replacement of a host insertion compound as cathode by a redox center for plating an alkali-metal cathode provides a safe, low-cost, all-solid-state cell with a huge capacity giving a large energy density and a long cycle life suitable for powering an all-electric road vehicle or for storing electric power from wind or solar energy.

I don't understand. That was surprisingly easy to understand, compared to the bulk of HN comments.
