This looks like a here and now, being currently manufactured, battery
approaching the concept of the bettery that Vorts brought up a few months
ago...

Don't feel bad. In the past two months, I have had to correct two
retired professors with Ph.D.s in EE who confused power and energy.
And *I* still make
What is the SCiB battery made of?
I think that everyone should know as much about everything
as possible. Secrecy does not help civilization extend
knowledge. People enthusiastic about batteries should
gravitate towards battery makers. Product users should be
as knowledgeable as possible

I just read The World Without Us by Alan Weisman. There
is a chapter on megatons of plastic trash in the ocean
which wears down to microparticles. Mr. Weisman writes
more about the North Pacific Gyre. Let's recover plastic
from there. Reusing plastic is probably better than
burning it for

These cars are disappointing. They have lousy gas mileage. By the old
EPA standard it was 40 mpg city, 45 mpg highway; by the 2008 standard
it is 33 mpg/city, 41 mpg highway. My 1994 Geo Metro gets that

I didn't mean to imply they were a good thing! They are also quite expensive
to service because everything is shoehorned in and one has occasionally to
take the whole drivechain out for repairs that would be easy in

They would be a good thing if they got the kind of gas mileage you
get with a motorcycle. Frankly, I do not understand why they don't.

That's for the cathode material, and it is nanostructured. The rest seems to be
standard Li ion battery materials.
It has all the features one can dream of for a Bettery (5mn charge, works down
to -30°C, 10 yrs life), except for energy density. From the page you quote:
The current capacity and

is an article on the A123 battery featuring a multiple
trace metal modified lithium iron phosphate nanoparticle
cathode and unspecified anode. The LIP material is better
and cheaper than lithium cobalt

They say here http://en.wikipedia.org/wiki/Lithium_ion_battery that the A123
battery has slightly lower energy density that other competing Lithium Ion
technologies.
Standard Li-ion (not high power): 150 to 200 Wh/kg (sez above article), so
slightly lower would be ~100 Wh/kg, twice ScIB's 50
