Any real lithium-based battery contains compromises, though, and in
principle you can do *somewhat* better by improving on those.

Notably, it wasn't easy to make *rechargeable* lithium batteries, and that
involved a number of compromises.  You probably could make a laptop
battery with rather startling performance... if you were willing to make
it one-shot, recyclable but not rechargeable.  It wouldn't be cheap.

(Me, I'll stick with my Psion Series 5 for working while traveling.  Small
monochrome screen with lousy contrast, and highly nonstandard software,
but I can read text and edit text and touch-type text quite adequately on
it, and that's generally enough for me.  And it fits in a belt holster.  
And, not insignificantly, it runs 20-25 hours on two alkaline AAs...!)
