Off topic.

If anyone is interested in batteries I suggest they research vanadium redox batteries.
Disclosure: I have a few shares in Camco Clean Energy (CCE)which has a share of REDT.
Obviously I'm biased.

For reference...

The battery pack in the Tesla EV roadster weights around 340kg using conventional lithium ion cells and does 250miles.

Edit:
Sandbag. Yes, SG was talking about the etchant gas but the volumes required were very low I believe.

That's sounds a very heavy battery
Just for fun 100m cars would be 100m kg - or 1m metric tons or 30 times more iodine than the world produces - so I would suggest they has better find something less rare. !
Could be used in smaller more portable uses!

Bobbyshilling

Using the numbers provided from Mr B's article I estimate a car battery would weigh 156kg for 500km range (typical EV efficiency is around 250Wh/mile).

Using the molecular weights of lithium and iodine and quoted energy densities I estimate the lithium/iodine ratio would be around 9.8/1.

Being a Redox battery there is a significant element associated with the electrolyte - say 50% the remainder being the lithium and iodine components. So each car battery would require 7kg of iodine and 70kg of lithium.

Very interesting - I might buy my 1 kg to eat early !
Be safe when the reactor in Japan finally melts down -

Thanks Mr b,
I read tonight on Fox News,the US Navy have developed a technology for creating fuel from seawater,a process that could keep ships at sea longer.

Anybody know how much iodine is required for a car battery? With over 1 billion cars world wide, even if 1 in 100 was battery powered in the future, that is over 10 million batteries! But I reckon more like 1 in 10 if it catches on.

MB
have a look at solid state Li ion batteries, a company called Ilika (LSE:IKA) have produced the first in the world and are in commercial discussions with the likes of Toyota
"Since mid-October 2013, Ilika has had a single solid-state lithium ion battery cell on test. The cell has been rapidly charged and discharged 2,200 times, which is equivalent to demonstrating a lifetime of around six years in a typical consumer electronics application. Demonstrations of longer lifetimes are in progress.
The performance data indicated above is now being shared with Ilika's OEM partners in the US, Japan and Europe reinforcing, and in some cases accelerating, commercialisation discussions."

Glad that caught your eye Mr Big. The more you read into it and see how quickly they are perfecting this cost effective Li-I2 battery it might not be as long term as we think! Its a solution the world needs asap to help combat the worlds carbon dioxide headache. I see China and Japan are pushing this technology hard.

[mister big] 09/4/2014 21:21

This deserves more research since potential for increasing iodine demand , implications massive albeit very long term .
The article suggests that electric cars could attend the same range as petrol cars . Interesting ! My m3 safe for the moment !!!!!

RIKEN team develops high-performance lithium-iodine battery system with higher energy density than conventional Li-ion
8 July 2013

The working concept of I3–/I– redox reaction in the aqueous Li-I2 battery. Zhao et al. Click to enlarge.
A team from Japan's RIKEN, led by Hye Ryung Byon, has developed a lithium-iodine (Li-I2) battery system with a significantly higher energy density than conventional lithium-ion batteries. RIKEN is Japan's largest research organization, with institutes and centers in locations throughout Japan.
In a paper published in Nature Communications, they report that aqueous lithium-iodine batteries based on the triiodide/iodide redox reaction show high battery performance. The high solubility of triiodide/iodide redox couples results in an energy density of ~ 0.33 kWh ;kg−1. The reversible redox reaction without the formation of resistive solid products promotes rechargeability, demonstrating 100 cycles with negligible capacity fading.
They suggest that a low cost, non-flammable and heavy-metal-free aqueous cathode can contribute to the feasibility of scale-up of lithium-iodine batteries for practical energy storage.
According to the Battery Roadmap 2010 announced by the New Energy and Industrial Technology Development Organization in Japan, the main target for rechargeable batteries is an improvement of the energy density up to 0.5 kWh kg-1cell (1.0 kWh l-1cell) by 2030 to enable electric vehicles to extend the driving range to a comparable level with gasoline-powered internal combustion engine vehicles (ca. 500 km) [311 miles]. However, achieving more than three times the energy density raised from the currently employed battery systems (99.5%), and cyclic performance (>99.5% capacity retention for 100 cycles) which is, to the best of our knowledge, the best result among previous reports using new chemistries and system configurations.

Quindell is in my view overpriced , in a market with huge regulated risks !
I'm interested in lithium iodide , and will look up !
From memory sqm produce both , so would be well placed I that one !

[bobsworth] 09/4/2014 20:49

Just the ticket!

Knowing, lithium iodide batteries have a very bright future which is fast approaching commercially (EV's and large-scale industrial grid storage), it is interesting that it takes 1.4 kg of recyclable iodine to generate 1 KWh of electricity!

That's a lot of new iodine needed!

With world supplies of Iodine already earmarked, Iofina's new source of good quality iodine could be just the ticket to fuel the new lithium iodide battery market.

Knowing the market looks to the future it might not be long before the market wakes up to this and sees Iofina's massive potential.

[florence10] 09/4/2014 20:25

Mr Big,sorry for off topic but have you an opinion on Quindell?
I gather it's a biz you are familiar with.

[mister big] 09/4/2014 20:16

In sense bears were right that the company had issues and news has shown cf leaving and the company pausing to review strategy .
The shares were rated with impossible growth expectations - they fell as they rose.
The price was pumped by bulls , derailed by bears - seems fair to me .

[superg1] 09/4/2014 20:07

Count

Thanks for that, unfortunately (if you see it that way) he went on a whim with all the misinformation that was being spouted. OM were getting out in a hurry (7 mill shares) and I know some here talked of bear insiders and all of that.

It can be no coincidence that PM got rid of the last tranche on the last trading day of the tax year.

No one can be certain where a supply is coming from.

I do pay attention to what the bears dig out on certain shares, but some methods used are to say the least 'highly suspect'. I actually welcome an active 'team' digging through the jungle of the AIM trying to weed out any dodgy looking accounts and businesses. They are out there, and dare I mention Meldex, that I know nothing about them but have seen it mentioned many times on threads.

There are a few that I think just don't look right, so I will be interested to see how they play out.

[mister big] 09/4/2014 20:03

I might add , he's quite often right on the short side,
But glad he has left the building !

[rhwillcol] 09/4/2014 19:21

Well, if you can stoop to just a "little" gloating, then you can certainly Count me in, Chris :) Especially as, on the back of EK and TW, some on here lost quite a lot more than that, and/or the anxiety which they deliberately induced. But I too am happy that sentiment has been turned around :)

[bogg1e] 09/4/2014 19:12

Cosseyed, naphar, apologies as what i stated earlier was off the top of my head.

This is from my notes which i first compiled last year so i cant say where the original data came from:

Mobile, truck-mounted mini-plants or "pods" are planned for sites with brine feeds of 7000 bpd or less (edit is that 8000 bpd now?). They are intended primarily for low volume sites, typically 3-4,000 bpd, with proven "hyper" iodine content (1-2000+ ppm). Such sites have been identified, but the differences between them is effecting the overall design process, as is the fact that a lot of equipment has to be installed in a confined space. Once the design has been standardised, "mass production" is possible, with only slight modifications required to achieve more automation (Edit: i believe the designs are now complete). Pods are a very attractive proposition; each costing approximately $200,000, or 10% of the cost of a 30k bpd plant, yet can handle 25% of the latters throughput. Furthermore, their mobility ensures Iofina has the flexibility to respond rapidly to one off opportunities or temporary fluctuations in brine flows at existing plants.

Edit: Im not so sure that a mini is 10% of an 30k bpd plant now, does anyone know for sure? (although its probably in my huge compilation of new notes!) Thanks.
