Aluminum battery science?

[Ernie]

Europositron makes some very intriguing claims for a new aluminum battery,
but I have not been able to find any scientific information. Is there some
information available on the SCIENCE of this battery?

http://www.europositron.com/en/background.html
gives the following link for patent, (inventor Rainer Partanen)
http://patinfo.prh.fi/julkaisut/viikkoluettelo/2005/22-2005.pdf
but this seems to be a list of patent applications; it does not contain any
information on the technology.

A search of the European Patent Office website,
http://ep.espacenet.com/search97cgi/s97_cgi.exe?Action=FormGen&Template=ep/en/home.hts
for inventions by Rainer Partanen found a number of documents in the Finish
Patent Office (which appears to be an internet "black hole" - no information
out) but no recent applications in other countries. The only accessible
patent seems to be WO9714824, published on 1997-04-24.

A quick search of the US Patent office website also failed to turn up any
recent patents or applications by Rainer Partanen;

Thank you,

I repost my previous replay to this:

80KW.h into 50 l and with 60kg! I have asked them about time to be
charged, and they told me 1 to 3 hours. With such parameters, the
electric car will be very competitive.

Al battery is not likely to be rechargeable, unless they use water-free
solvents (considering that Al reacts with water).

Non-rechargeable Al-based battery would be somewhat similar to
fuel-cell, it would produce H2 which than would react with oxigen.
Somewhat similar to existing Zn-oxigen cells. This could work
and have higher energy densities with Al than with Zn. But the
company above does not seem to follow this approach.

The site is very chaotic, tends to sensationalism and does not provide
enough information how they approach making Al-based rechargeable
battery or how their claims can be verified.

One funny thing, they say that their future fantazy 80kWh / 50l battery
is 20 times better than existing batteries. However, considering that
state of the art Li-ion battery is 600Wh/l , their unconfirmed fantazy
battery would only be 2.6 times better than Li-ion and not 20 times.

If they can not get their story straight even with their future plans,
you can judge for yourself about everything else.

This came up in this forum a couple of years ago, it looks like snake
oil, and
the fact that they haven't commercialized it since then is even more
evidence
against them. Search out the old posts.
