[EVDL List]

Has anybody heard any thing about this new type battery? It is in the EV
world news report.
. ( The new technology converts the magnetic energy directly into
electrical energy, without a chemical reaction. The electrical current made
in this process is called a spin polarized current and finds use in a new
technology called "spintronics."

Sounds kinda like a new "spin" on scamming?

I'm new on the list (no EV yet) but had to respond to this one because
I am a scientist.
I just googled 'battery spin polarized current' and found that this is
for real, but is a research finding published in one of the top
journals, Nature. If you want more details, here is a link to a
description of the research.
http://www.sciencedaily.com/releases/2009/03/090311162807.htm
I am a chemist myself. This is a physicist's idea for a battery, so I
don't fully understand how it might work. Wait a few years to see if
anything comes of it.

Spintronics is a real branch of research. Spintronics is solid-state
electronics that uses the the quantum spin of electrons. It has some
interesting applications to computer memory; it might replace flash
memory 10 years from now.

I've never heard of spintronics in regards to energy storage, though;
I'm pretty sure any battery based on spintronics is a hoax.

Its not the spintronics I'm familiar with (when will my %#&^#%ing patent app
be out of security review?), but I suppose some overlap in terminology is
acceptable.

I am not certain that magnetic field energy will be as dense as desired. Not
because the initial storage is not dense, that is fantastically dense, but I
can't see any way of preventing leakage.

To my eye the fundamental problem is that the only way to trap a magnetic
field would be through a Faraday cage or a more powerful magnetic field. For
somewhat obvious reasons containing the field in a stronger magnetic field
gains nothing. Leaving only the Faraday cage, unfortunately when containing
a magnetic field the cage itself very quickly enters a state where it
becomes magnetized, creating this magnetic field drains the contained field
and allowing it to pass through to the outside, only more slowly. This
provides the same self-drain problem that we have argued back aand forth on
with Ni* and liquid salt batteries. While this isn't necessarily a horrible
thing, my understanding is that while at first the cage may be nearly
impermiable, the permiability will increase in an exponential manner, that
provides a strong lifetime term for the device.

Unless I'm missing a very significant breakthrough, I read the summary for
the Nature paper cited by Sherman, I don't see this breakthrough. It
magnetic spin cells have existed for years, the actual use is that the MR
effect (magnetoresistive) changes the resistence of the material in the
middle. From my familiarity with Tanaka's prior work I'd say it is likely to
do exactly what the summary says, he is not known for flights of fantasy,
the last sentence of the Nature summary "The ... e.m.f. may find potential
applications in ... new active devices such as 'spin batteries'" so he
didn't find any way of really using it, but sees possibilities for applying
it given enough further research. From the available figures it appears that
the design is not paricularly energy dense, at the current level (nano
cylinder, ~25nm diameter, ~60nm tall) probably won't even reach the density
of lead acid, simply due to wasted space, modern lithography makes it
effectively impossible to pack circles in anything but squares.

Right now this is an early research situation, in 10 years we might be able
to plan on using it, in 12 years we might see early adopters, and 15 years
first mass adoption. From such a timeframe it is impossible to determine
what the energy density will be when market capable research is possible.

I'd be glad to be proven wrong, but I think that's the current status.

I hope we are not going down this road again. : (
