True for chemical batteries but EEStor devices store energy as an
electrostatic charge. If their press is to be believed, they have 10 - 100x
the capacity per pound as lithium ion. Even with lithium chemistry, silicon
nanowire anodes from Stanford promise 10x the charge.

Electric power is a fast moving target these days. Who is to say what might
be possible. Don't write it off too quickly.

One major problem with battery powered electric systems is that all the
reactants must be carried onboard. This puts them at a major
disadvantage with fuel burning systems. An aircraft with a fuel burning
engine only has to carry its fuel onboard, the oxidizer is pulled out of
the air. This give a fuel burning engine a major weight and range
advantage over a battery powered electric system.
