Nice list, you might add TNT at 9.5, Then there is air pressure
storage not sure where it fits(do you count the pressure vessel as
part of the mass?), and gravity storage. (I'm thinking of pumped
water reservoirs. ) down at 0.5.

Yes, TNT's claim to fame is it's rapid explosive reaction not it's energy
density. Chemical explosives are NOT particularly energy dense compared to
common fuels. People confuse energy density with the ability to detonate
into volumes of gas very rapidly; i,e, explode. They aren't the same thing.
Well, not everybody does. Since that's why the people who actually
understand
the issues work on Self-Replicating Machines, rather than with
Quantum-Chemistry
idiots from GM
And work on GPS, Digital Terrain Mapping, SGML, XML, Electronic

Atomic Clock Wristwatches, Light Sticks, Compact Flourescent

The problem with a large mature company isn't that it'll make wild
claims but that it won't make any claims at all. Even so it was
interesting that they sought out MIT to check their work and bolster
their case.

Wasn't it IBM that came up with carbon nanorods
that are supposed to revolutionize battery capacity?
As anodes they were supposed to multiply the
capacity of batteries by 10x.
What was the enhancement that already
multiplied the capacity of NIMH batteries by 10x?
I think you refer to the Stanford nanowire anode development by Yi Cui,
professor at Stanford.
http://news.stanford.edu/news/2008/january9/nanowire-010908.html
That development applies (and refers) to traditional technology (lithium ion
and such), not the Lithium-air battery proposed here.
still stands and as far as I know they are exploring commercialization.
One recurring issue with these nano technology is upscaling (and keeping
production cost low).
From another report :
"The downside is that the nanowire growth process that Cui uses, which feeds
gaseous silicon to a liquid gold catalyst to make the solid electrode, is a
high-temperature (600 to 900 °C) process that could be costly to scale up.
Cui believes that scale-up of the vapor-liquid-solid process is nevertheless
feasible, but he acknowledges that he is also "exploring another approach."

Don't know this one.
In general, there are many research and development projects ongoing to find
a low-cost, high-capacity battery suitable for the expected PHEV market. You
will see all kind of new developments, one claiming even bolder improvements
that the next.
Which one of these alternatives will make it to commercialization is unclear
at this point.
Just let research and development and production engineering do it's thing.
But one thing is sure : there will be improvements in both energy capacity,
power density and cost reduction.

Well, since that's also why the people who actually understand
engineering, rather than
internal ibm gibberish work on C++, Distributed Processing Software,
Pv Cell Energy,
All-In-One Printers, Digital Fiber Optics Signalling, Multiplexing,
Corner Turning, USB,
Mini Hard Disks, Electronic Books, Cell Phones, GPS, Digital Terrain
Mapping,
Atomic Clock Wristwatches, Holographics, Holograms, Post GM Sockets,
Self-Replicating Machines, Self-Assembling Robots, UAVs, AAVs,

Banking, On-Line Shopping,
On-Line Publishing, Compact Flourescent Lighting, Light Sticks,
Solar Energy, Biodiesel,
Gas Turbine Engines, and Hybrid Electric Trucks and Cars, it's also
an issue that only
Quantum Mechanics and Ford idiots worry about anyway.

Too bad if they can't combine them.

High temp and lots of GOLD? Yowch.
Does the gold end up being consumed or
incorporated into the resultant product?
The consumer NiMH rechargeable AA's ON STORE SHELVES
have gone through two major changes in the last few years.
1. Eliminated the ""memory"" problem
2. 10x capacity
Those are big changes but I haven't seen any explanation
of how they did it.
