I thought I'd give our friend (I'm in a
cheritable mood) MGV the honor of appearing as the last wax
museum exhibit for 1999. There will be lots more in the
new year, of course.
Here are some choice
comments from the post below:
"My position has been
both clear and consistent throughout. It is: VLNC
fails because is doesn't execute."

of it's own weight."
I'm afraid all his VLNC
predictions during the past year will be proven wrong. I'm
even betting big bucks on
Happy New Year to one and all!
More details on poly now?--an unintended and

Re the patent question:
it's an interesting situation.
First of all,
the B patent appears to be broader in its claims,
since the G patent claims only two specific
crystallographic structures (olivine and NASICON) and only 4 metal
cations (Mn, Co, Ni and Fe). However, it was filed
earlier as a provisional filing in April '96.
B patent covers a broader range of metal cations
and structures, but it was filed later: Sept.
I would guess that the examiner was convinced by
the filing parties there was a difference between
them, but stranger things have been happenning recently
at the USPTO (for example, the (in)famous 6,007,588
'windowing' Y2K patent).
I'd like to see the

interested in your report from the 'bowels of the beast'
tonight... no doubt you'll have some stories to tell, eh?
Just funnin' ya!
for a happy, healthy, and even *more* prosperous new
year to you, too.
the '111' is now not an unrealistic price target for
a 1-2 year time frame, 'methinks' !
Well, I took advantage of this mornings dip,
which to my mind is that final year-end "adjustment",
to get me a traders block at ~$18 1/2. So I'm set
for next year.
As I hope everyone else
So I mirror M(sub)E's thoughts. Time to get ready
for tonight. And I'm gonna be right down in the belly
of it all, in NYC(call me crazy). It should prove
interesting. I'd like to take this time to wish for everyone a
safe evening, surrounded by those you love, and who in
turn love you.
Another question comes to mind: some time ago
we'd been hearing various numbers as to the royalties
paid by the lithium-ion manufacturers to the Harwell
group for the right to use the lithium-cobalt
From what you know, what was the royalty percentage
paid, and what was the pricing structure? (Was it a
percentage of the final sales price, for
Thanks in advance for your time.
Wishing you a
happy, healthy, and prosperous new year.
Mkt_entropy, thanks for your recent detailed
posts regarding the battery chemistry.
to be posting more details about the polymer
technology than before, have you been talking to some of the
researchers, reading some papers? (As I recall, your personal
interest was more with the liquid electrolyte
Here's a question: can you perceive any difference in
the Barker and Goodenough patents on 'lithium
containing phosphate cathodes'? I noted that the same patent
examiner granted them, Barker's being issued some months
prior to Goodenough's. As I recall, the chemical
compounds differed only in the order listed for the
molecules. Have you any suspicions if that is significant?
A good graphite shows less than 6-8% irreversible
passivation loss, so how much could you gain by using the
"third electrode"--nuthin', like dkctx says, and how
much trouble would you be asking for for the few-%
gain?... They don't know what they're talking about. This
patent you have in mind is not worth the paper it's
printed on. Full of crazy numbers.
When the truth
comnes out (as soon as somebody competent tales apart
their Superpolymer (ha! ha!) battery), we will learn
that what they have done is glued standard electrodes
to a standard separator--like Sony, but in a flat,
prismatic, large-area form. That's what all their previous
patents are about; that's what DasGupta was showing a few
years back. Note my words. There are no other tricks
OK, time to dress up. Champagne's
The 312 volts of lead acid on the ev1, nominally
55 ah, or 16 kwh, generate 100 kw (!) for about 300
kg of weight.
NiMh generate about 50-90 kw for
the same weight, I'm told.

is plenty powerful, as shown by the Nissan Altera.
But its "specific energy", or capacity, is not as
high as one would expect from Li, as shown by its puny
range. That's why the only thing that matters for large
applications is generally kwh, because that tells you how far
it can go.
The exception is zinc, whose 2v
cells have a very low discharge rate--that's why they
are working on hybrid battery/battery
