Sion and Lithium Sulphur

[Rush-5]

Someone asked me about Sion here in Tucson and the Lithium Sulphur batteries
that they are producing. Can anybody give me some info about the battery
chemistry as compared to Lithium Ions?

All the info that I can find from a google search seem to indicate that the
watt density is much better, but the cycling is way down, around 300. I
remember seeing a PBS show about the fact that most of the lithium is owned
by Brazil (I think) and that it might be a problem buying such a large
quantity needed for mass production.

Any info would be helpful, TIA

Dear Rush:

Sorry, I don't know about Sion.

But regarding the world's large Lithium reserves, USA have 3,8%, Bolivia
50,5%, Chile 28,1% Brasil 1,3% and China 10,3%.

In Latin America, Brasil is the largest producer of auto parts, with big
industrial park and all infrastructure - 85% of all energy is hydro-electric
- and many battery companies from USA, China and Japan are dealing to open
facilities here - there's a common market for South America, named Merco Sul
- in order to produce/export and also to sell in the future market of EV´s
in Brasil and Mexico.

Since the end of World War II <http://en.wikipedia.org/wiki/World_War_II>,
lithium metal production has greatly increased. The metal is separated from
other elements in igneous mineral such as those above, and lithium salts are
also extracted from the water of mineral
springs<http://en.wikipedia.org/wiki/Mineral_springs>,
brine pools, and brine deposits.

The metal is produced
electrolytically<http://en.wikipedia.org/wiki/Electrolysis>from a
mixture of fused lithium and potassium
chloride <http://en.wikipedia.org/wiki/Potassium_chloride>. In 1998 it was
about US$ <http://en.wikipedia.org/wiki/US_dollar> 43 per
pound<http://en.wikipedia.org/wiki/Pound_(mass)>($95 per
kg <http://en.wikipedia.org/wiki/Kilogram>).[41]<http://en.wikipedia.org/wiki/Lithium#cite_note-ober-40>

Deposits of lithium are found in South America throughout the
Andes<http://en.wikipedia.org/wiki/Andes>mountain chain.
Chile <http://en.wikipedia.org/wiki/Chile> is currently the leading lithium
metal producer in the world, with
Argentina<http://en.wikipedia.org/wiki/Argentina>next. Both countries
recover the lithium from brine pools. In the United
States <http://en.wikipedia.org/wiki/United_States> lithium is similarly
recovered from brine pools in Nevada <http://en.wikipedia.org/wiki/Nevada>.[
42] <http://en.wikipedia.org/wiki/Lithium#cite_note-lanl-41>

Nearly half the world's known reserves are located in the Andes-containing
country Bolivia <http://en.wikipedia.org/wiki/Bolivia>, which in 2009 is
negotiating with Japanese and French firms to begin
production.[43]<http://en.wikipedia.org/wiki/Lithium#cite_note-romero-42>According
to the US Geological Survey, Bolivia's
Uyuni <http://en.wikipedia.org/wiki/Uyuni> Desert has 5.4 million tons of
lithium, which can be used to make batteries for hybrid and electric
vehicles.[43] <http://en.wikipedia.org/wiki/Lithium#cite_note-romero-42>This
is the largest amount of lithium in any country, compared to Chile's 3
million tons of lithium and the United States's 760,000
tons.[43]<http://en.wikipedia.org/wiki/Lithium#cite_note-romero-42>
[44] <http://en.wikipedia.org/wiki/Lithium#cite_note-43>

China may emerge as a significant producer of brine-based lithium carbonate
around 2010. Potential capacity of up to 55,000 tons per year could come
on-stream if projects in Qinghai
<http://en.wikipedia.org/wiki/Qinghai>province and
Tibet <http://en.wikipedia.org/wiki/Tibet>
proceed.[45]<http://en.wikipedia.org/wiki/Lithium#cite_note-Legers-44>

The total amount of lithium recoverable from global reserves has been
estimated at 35 million tonnes, which includes 15 million tons of the known
global lithium reserve
base.[46]<http://en.wikipedia.org/wiki/Lithium#cite_note-Tahil-45>

In 1976 a National Research Council Panel estimated lithium resources at
10.6 million tons for the Western
World.[47]<http://en.wikipedia.org/wiki/Lithium#cite_note-46>With the
inclusion of Russian and Chinese resources as well as new
discoveries in Australia, Serbia, Argentina and the United States, the total
has nearly tripled by
2008.[48]<http://en.wikipedia.org/wiki/Lithium#cite_note-47>
