Your brain is perfectly normal.
You remember what is important in your life and forget about stuff not so crucial. :wink:

Hey Loser-Boy! Why the concern?
 
Interesting discussion from a recent TV doco about off grid storage etc..
More competition for Tesla's Powerwall...
And potentially a cheap gell cell pouch that recharges in a few mins, can be safely discharged 100% , and is made from a fire retardant gell ! :shock: :mrgreen:

NARRATION
Around the world, the race has been on to develop a better battery than the current lithium configuration. And some of the top contenders are right here in Australia, such as Professor Thomas Maschmeyer. He believes he’s just invented the battery that will change everything.

Professor Thomas Maschmeyer
This is our battery, it’s based on zinc bromide. So, we’ve got the two electrodes here and what’s called a coin cell, and then the key part is that we have a gel that we put on top of the electrode.

NARRATION
Zinc-bromine flow batteries exist already. They use a liquid to transport the changed particles, which has its advantages, but they’re too big to fit in a phone or computer. Thomas’ breakthrough idea was to take a zinc-bromine battery, but instead of a liquid, use a gel. So why a gel? Well, it’s neither a liquid nor a solid, but you get the advantages of both. And that includes being able to move ions quickly, so you get rapid charging.

Dr Jonica Newby
So how quickly does it charge?

Professor Thomas Maschmeyer
We can get it down to just a few minutes.

Dr Jonica Newby
Really? So you’re saying I could charge my phone in just a few minutes.

Professor Thomas Maschmeyer
In just a few minutes. And not just your phone, but also your car.

NARRATION
Already the batter is running at 90% efficiency, which is higher than in your mobile phone. It has a longer lifetime and zinc is cheaper than lithium.

Dr Jonica Newby
So if this becomes commercialised, it’s cheaper, you can charge it faster, it lasts longer…

Professor Thomas Maschmeyer
And the gel is made out of a fire-retardant material.

Dr Jonica Newby
It’s fire-retardant as well?

Professor Thomas Maschmeyer
That’s correct.

Dr Jonica Newby
That’s pretty impressive.

Professor Thomas Maschmeyer
Well, thank you very much.

NARRATION
But perhaps its biggest potential lies in the fact that being a gel, it’s bendy. It won’t crack. And that’s what excites this industry. The potential is for flat pack zinc-bromine batteries to be included in the very fabric of buildings. Lendlease is just one of the big companies that’s been inspired by Professor Maschmeyer’s vision.

Steve McCann
It’s very exciting, his work. Our vision is to create the best places. To do that, you have to continue to innovate. And we’re thinking about things like working with Professor Maschmeyer to use prefabricated wall segments, for example, as, effectively, battery storage or power storage facilities. So imagine that in a large scale and the impact that will have on the emissions from the built space, which is a very significant impact on the environment.

ES Search found 25 matches: +"Lithium Sulfur"...

Mentioned again as [C]omment to article "How To Invest In The Booming Global Electric Motorcycle Market"
http://seekingalpha.com/article/3874206-invest-booming-global-electric-motorcycle-market

Lithium Sulfur batteries have now been commercialised by Oxis Energy in the UK and Sion Power in the US. Up to five (5) times the energy density of regular lithium ion batteries.

Tesla CEO Elon Musk should dedicate a portion of their battery Gigafactory to producing them under license. In this way, if they have real life problems, it will be limited to a smaller amount of vehicles. Then, over time, they can make less regular batteries and more and more of these ones as they prove themselves...

Even if it's the same energy density now, the price is significantly cheaper because of how cheap sulphur is compared to the current materials used. I believe it uses less less lithium as well.

Regarding Oxis lithium sulfur batteries:
"An energy density of 400 Wh/kg is forecast for 2016."
See: http://bit.ly/1W7qQBs
(As of 2014-10-19 - the cells in Model S currently offer a specific energy of 233 Wh/kg due to the NCA chemistry and high-density electrodes. This is roughly 50% greater than the current industry standard, exemplified by the LEAF at 155 Wh/kg. - See: http://bit.ly/1zvtAM3)...

I believe the battery has been tested inside a high altitude UAV already. Between now and 2019 they are doing a lot of tweaking to further improve the energy density. Airbus and other big players are also involved.

Your getting close to lead in the size/weight categories. That makes the range a huge issue.

Hehe... Learned long ago that "slower is better" in batt range per charge terms. Less aero drag/wind resistance, yes? Living in an Urban World full of stop and goes, to avoid needing/using batteries as much as possible. So, instead using gravity (down hills), coasting to any stops... pedaling (kicking) from stops then *gently* adding power to shave peak outputs... Lessee... Watt else... Hehe
 
At least 10x longer cycle life than Lifepo4 @3C
So in theory LTO is cheapest battery on the world overall cost per mile.

My Ebike Lifepo4 lasted ~600cycles @ 2.7C
50% left.

I plan to loose my own weight ~20kg for LTO
16kg to go :lol:

Probably good for stationary storage? But 2x more expensive than LiFePO4 means what, 10 times lead acid?

Yeah I would agree.
http://www.ev-power.eu/LTO-technology/Lithium-Titanate-Oxid-Battery-Cell-LTO-2-4V-10AH.html
Not talking about you in anyway but sometimes I think some folks here don't consider cycles in 18650s vs lipo etc which can really add up...
What I do like to do is look at total kwhr/s in total cycle usage because if folks don't ever do this once then there is little reason to compare your batteries to single discharge Alkaline AA batteries etc..

So assuming both these LTO and Lipo cells have the same degrade capacity level for their total cycle life time we could do this as comparison..
That URL above 20,000 cycles at C1 discharge..Nominal voltage 2.4v with 10Ah capacity.
So that's 2.4 x 10 = 24whrs per cell.. times that by 20,000 and its
24 x 20,000 = 480,000 whrs of power it will give over the LTO cell lifetime..
If we compare that to say a single cell of a 10Ah multistar http://www.hobbyking.com/hobbyking/store/__56845__Multistar_High_Capacity_6S_10000mAh_Multi_Rotor_Lipo_Pack.html
Its 3.85 x 10 = 38.5whrs per cell, cycles say 500?
38.5 x 500 = 19,250 whrs of power over its lifetime..
So with 480,000 whrs in LTO vs 19,250 whrs in lipo in this area alone putting aside weight and size etc you can see some real advantages if the total cycles promise is true..
If you doubled the amount of LTO cells so you could have a higher discharge rate as it says on that URL above for 50,000 cycles total then you get a total life time worth of 1,200,000whrs of power out of that Lithium Titanate cell, vs 19,250 LTO makes lipo look like crud.
Sure you could argue that if lipo was treated at 0.5C rate discharge it might magically perform the same way but HK etc never promise or even wish to push such hopes in the first place, they would rather tell you their cells are full of graphene https://endless-sphere.com/forums/viewtopic.php?f=3&t=76035&start=25#p1150043

I agree, LTO cells offer much higher cycle count. Doubling the cell count is similar to decreasing used capacity of 18650s. I'm not talking HK junk, but quality cells. If not held 100% SOC and limited to 20-70% SOC (doubling the amount of cells), these could easily give several thousand cycles. Tesla proved it is possible: 5% decrease in capacity after 100k miles. Of course it is quite different to industrial usage, but results are good.

I am sure LTO cells will find their way, if some good marketing is applied. Same issue is still relevant to LiFePO4 cells: they offer much better cycle and calendar life than lead acid batteries, but these are still being used heavily. Because initial costs are much lower and it is not that easy to convince the new tech will hold at least 15 to 25 years.
I say years will go by until these get used, if they are actually any good. As I'm sure there are some small things they are not telling us, like *capacity degrades by 50% withing one year if kept charged above 80% SOC

a “multicomponent-approach to enhance stability and capacitance in polymer-hybrid supercapacitors.”

Seen here "New “Super Battery” Energy Storage Breakthrough Aims At $54 per kWh"
http://cleantechnica.com/2016/02/26/new-energy-storage-solution-could-hit-magic-54-mark/

BioSolar has a research agreement with the University of California, Santa Barbara, and earlier this week the company and the school reinforced a previous international patent application by jointly filing applications in the US, Canada, and Japan for something called a “multicomponent-approach to enhance stability and capacitance in polymer-hybrid supercapacitors.”
Click to expand...

Biosolar has solved the cost and capacity problem in one blow, by developing an inexpensive polymer for the cathode:

Our novel high capacity cathode is engineered from a polymer, similar to that of low-cost plastics used in the household. Through a smart chemical design, we are able to make the polymer hold an enormous amount of electrons.

…The estimated raw materials cost of our cathode is similar to that of inexpensive plastics, with a very high possible energy density of 1,000 Wh/kg.

BioSolar’s research also indicates that the new polymer enables batteries to charge and discharge rapidly while far outlasting the lifecycle of conventional lithium-ion energy storage.

According to the company, conventional batteries drop down to 80 percent of their storage capacity after 1,000 charge/discharge cycles. When the new polymer is used in a supercapacitor, BioSolar’s labwork has demonstrated a lifespan of 50,000 cycles without degradation (a supercapacitor is a type of energy storage device that discharges quickly).

It looks like BioSolar has some more work to do before it is ready to publish some definitive conclusions about its energy storage solution for EV batteries, utility scale storage, and other applications that require slower, steadier discharge. However, the company is confident that it is heading down the right track.

I searched ES and didn't see this one, but I bet somebody posted about it somewhere...

It's called the Johnson thermoelectric energy converter (JTEC). Not a battery (OK, off topic a bit) but a generator that converts heat into electricity.
They claim efficiency of nearly 60%, making it about twice as efficient as an internal combustion engine. No moving parts either.

https://en.wikipedia.org/wiki/Johnson_thermoelectric_energy_converter

http://johnsonems.com/our-technology/

The Johnson Thermo-Electrochemical Convertor (JTEC) is an all solid-state device that operates on the Ericsson cycle. Equivalent to Carnot, the Ericsson Cycle offers the maximum theoretical efficiency available from a converter operating between two temperatures. The JTEC system utilizes the electro-chemical potential of fluid pressure applied across a proton conductive membrane (PCM). The membrane and a pair of electrodes form a Membrane Electrode Assembly (MEA) similar to those used in fuel cells. However, in the JTEC the hydrogen circulates continually inside the device, which is different from a fuel cell in which hydrogen is consumed and must be continually replenished.
