Re: Thread for new battery breakthrough PR releases

So has anyone got any kind of roadmap in the back of their mind on where batteries are going?
A round up of what they believe might actually come in new battery technology?

This thread is almost 11years old now and you can go back 10 years and read posts promising ridiculous stuff like 800Wh/KG 20,000cycles and 800c-rates with mass production in 3 years time.. which would mean these amazing new batteries have been mass produced for the last 7 years but no ones seen or heard from them. :?

I was just reading about Elon Musk having his own design/dream for a VTOL electric plane, says that such a system becomes possible once battery energy density reaches over 400 Wh/kg, while his Tesla vehicles are believed to be currently powered by battery cells with ~250 Wh/kg.

So googling around for 400Wh/kg in news comes up with interesting stuff, but its rare to get a mass production release date.
This Sion Power’s Licerion Lithium Battery did come up with a 400Wh/kg promise, funded by BASF and mass production date of late 2018!
https://cleantechnica.com/2018/04/02/is ... iting-for/
But its problem is that you only get 150cycles, so its only good for very rich/expensive application needs like military UAV.

https://c1cleantechnicacom-wpengine.net ... hium-1.png

And this is something I actually like to see in these very high spec battery promises, that is low production even if it's so expensive its only for military UAVs or to fly Bill Gates around in an electric air-craft. I am SURE there is a market, for ridiculously expensive high-performance batteries, thats why when I see these amazing specs I don't believe them because I am sure someone is willing to pay for it even if its 0.1% of the market.
I absolutely hate the high spec claims but never ever any production even if its for military/satellite market, because it makes it hard to believe it was ever real at all.

So even though Sion Power’s Licerion is kind of useless for ebikes/cars/flying-car mass-market in its current form at the very least its coming.
Does anyone know of anything else that has some pretty impressive battery specs thats actually got a production release date?

Hehe... Forgot about Sodium-ion... Wiki:
https://en.wikipedia.org/wiki/Sodium-ion_battery

Includes:
Battery-grade salts of sodium are cheap and abundant, much more so than those of lithium. This makes them a cost-effective alternative especially for applications where weight and energy density are of minor importance such as grid energy storage for renewable energy sources such as wind- and solar power.

i believe that iz the point of this thread, beyond saving space/easy reference.
new tech of all stripe routinely getz deliberately suppressed.
by lumping all the announcements in one place makes it blatently self evident as you noted.

This is promising. The scib battery has been around for awhile. Great at everything but capacity but sounds like they might have fixed that.

If this wasn't from one of the big players, I'd immediately call BS. But..Toshiba is a "real deal" company. They are claiming 5,000 cycles and still delivers 90% of the new battery range. I'd be happy going from 1,000 cycles to 2,000 cycles, so,..this is pretty huge.

I also like how the test cells have the tabs on opposite ends, especially now that I've seen research on cooling a cell like this by cooling the tabs instead of the foil packet external sides. Having the entire end for just one of the tabs increases the size of the tab. Good for cooling, and good for accessing high current.

....Japan pushing Solid State Li EV battery commercialisation.
TOKYO -- Leading Japanese manufacturers have teamed up with the government in a program to develop solid-state batteries, which are expected to power the electric vehicles of the future.

Kicking off in May, the program teams the Consortium for Lithium Ion Battery Technology and Evaluation Center, or Libtec, with companies like Toyota Motor and Panasonic to develop the highly efficient battery.

The program is aimed at returning Japanese manufacturers to the forefront of automotive battery technology, as international rivals have eroded their once dominant position in the field.
....To support development, Japan's Ministry of Economy, Trade and Industry will provide 1.6 billion yen ($14 million) in funding to Libtec, a research body whose members include Asahi Kasei and Toray Industries.

Toyota Motor, Nissan Motor, Honda Motor, Panasonic and battery maker GS Yuasa will also participate in development.

Been a few posts over the years about SolidEnergy battery, these guys did have a "release date of early 2017" but failed but they are finally here now.
http://www.solidenergysystems.com/

Because we have seen so many of these over the years the claims dont raise an eyebrow because they never come. I think we are currently at the point where a 400-500Wh/kg or 1200Wh/L battery could slap us in the face and we wouldn't notice because these claims have been around the corner for 10 years with nothing to see, since forver.

Well these guys are selling their battery, very expensive but still all good.

http://www.solidenergysystems.com/technology/
400Wh/kg and 1200Wh/L is what they claim.
http://assets.solidenergysystems.com/wp ... ePaper.pdf

As I posted at the top of this thread, I wanted to find something thats "actually buyable" even if its not affordable for everyone right now, this looks like it.
I am surprised Elon isn't all over this.
I think SolidEnergy should have a conference with dancing girls on stage to help drill it through, maybe hire the Formula 1 grid girls that were sacked due to the imbalance of views or overwhelmingly out of control deluge of feminists rant videos on Youtube/Facebook vs conservationist-right-wing points-of-view that are all now banned.
https://www.thesun.co.uk/sport/motorspo ... rix-races/

Just made a grid girl 500Wh/kg celebreation meme. I think I make these just to see how fast I can knock it out.

Didn't find any online store with those solid energy batteries. So no indications those cells are actually being sold.
The long and hard way to market is what makes any articles about battery companies newest thing almost like white noise. Your brain auto shut down because you know there ain't no way we are going to be able to buy those products today or any day soon.

When I first read up on this corner of the forum I was hyped at all the new technology "just around the corner". Now when I read I realize its a tease and that most of the stuff will be dropped or will take 10+ years. Honestly I should be reading the Cryogenic forums to see when I can be put into cryofreeze so I dont have to wait for these damn batteries to come to market.

Sometimes when I read articles in here I feel like im watching an episode of Nova and how scientists are working on ways for interstellar travel.

Their website says they are producing batteries in low volume under contract to some high-end clients.

They have a contact button, if there was someone who was a genuine interest/customer who can afford to buy these somewhat handmade USA batteries I would bet they would come through and we can then see.
But the website on there somewhere clearly state they are currently only in low production for high-end applications/clients.

Can you find a price quote? News: Toyota, General Motors, Daimler haven't contracted them... So, there must be an issue with the batteries. Someone can try them in a quadcopter already? Perhaps they are not powerful enough for RC and drones. It's totally usable for a bike the graph states 0.1C charge and 0.5C discharge for a rapid wear rate. It's good only if it's cheap. They limited the range at 120 cycles, looks like they don't want to give more information than 120 cycles. It has to at least compete for a place on the RC market to be a competetive chemistry. If you can have 3 cells in parralel, it gives you a discharge of about 10A, which is definitely possible with their 29g cells, we can arrange 40A batteries:)

Why have the quadcopter forums not received one of them?

SolidEnergy FAQ:

How can I request a sample?

Please kindly send us an email in the Contact page with a brief description of your application, technical requirements, volume, timeframe and your story. Please understand that while we would love to send sample cells to you, we have a limited production capability, and must prioritize our demand. Please accept our apology if we don’t respond in time.

If you know how to write an energetic and enthusiastic letter to SolidEnergy, to sample their cells, hype it up on the web, create public awareness for the brand whatever, you can perhaps get a cell to review at home, and make the first home user video about SolidEnergy batteries...

It's actually usable for a 2400 watt ebike.

.5C is 6W (=.5*4v*3Ah). although they are recommended for 1C continuous discharge, which is 12W. So, for 290grams, you get 120Watts, and for 6 kilos of them, you get 2400watts, and 2400 Watt-Hours too!!!

They're saying $100/kWh of cells within the year, $100/kWh for the whole pack within the following year. Here's hoping.

I think its about right. They have the team and the equipment. The trick is to work on both energy density and energy vs cost. If they have been working on that for about 10 years and grown to the size they are I think the numbers are believable.

Why developed new batteries?
There isn't real "battery buyers", only dreamers.
100$/KWh is a fake. Impossible.
And even with lithium, we never see something with more of 300Wh/kg.... and very dangerous.

In 1898, delegates from across the globe gathered in New York City for the world’s first international urban planning conference. One topic dominated the discussion. It was not housing, land use, economic development, or infrastructure. The delegates were driven to desperation by horse manure.

The horse was no newcomer on the urban scene. But by the late 1800s, the problem of horse pollution had reached unprecedented heights. The growth in the horse population was outstripping even the rapid rise in the number of human city dwellers. American cities were drowning in horse manure as well as other unpleasant byproducts of the era’s predominant mode of transportation: urine, flies, congestion, carcasses, and traffic accidents. Widespread cruelty to horses was a form of environmental degradation as well.

The situation seemed dire. In 1894, the Times of London estimated that by 1950 every street in the city would be buried nine feet deep in horse manure. One New York prognosticator of the 1890s concluded that by 1930 the horse droppings would rise to Manhattan’s third-story windows. A public health and sanitation crisis of almost unimaginable dimensions loomed.

Well, here we go again.......
The full article is here: https://newatlas.com/nawa-technologies- ... tor/54972/
Ultra-capacitor hybrid radically boosts power and efficiency of lithium batteries.
Snip........For starters, while power density (the amount of power output per unit of weight) is off the charts, energy density doesn't compete with lithium. An ultra-capacitor will only hold about 25 percent of the energy per unit of weight that a lithium battery can manage, so a car battery with the same sized ultra-capacitor would have only a quarter the range.

Secondly, capacitors suck at long-term energy storage. Leave your car charged up in your garage, and you could expect to leak around 10-20 percent of your energy out each day.

The Nawa team believes that the full potential of the ultra-capacitor, at least in the EV space, becomes unlocked when it's combined with a lithium battery.

A hybrid lithium/carbon battery system could offer the best of both worlds – long-range continuous driving and long-term power storage thanks to the lithium unit, plus ultra-fast partial charging and extreme power output thanks to the ultra-capacitor.

This kind of hybrid system has another hidden advantage: regenerative braking would become about 450 percent better at recouping energy. Current re-gen systems are forced to throw away the vast majority of energy generated back through the wheels under braking simply because lithium charges so slowly that there's nowhere to put it all.

"Most of the energy in regenerative braking is lost as heat, maybe 80 percent," says Grape. "Perhaps 20 percent is recouped. The electric motors are very efficient at generating that power, but the battery just can't accept the charge rate. If you combine our technology with the lithium battery, we can accept up to 90 percent of that energy."

In a regular driving situation, that could handily extend your battery range. In an electric race car, this kind of system would be even more effective, storing almost all of your braking energy coming into a corner, and then pumping it back out at a massive rate for huge acceleration out of the turn.

"For example, let's take Formula E racing," says Grape. "If you look at the batteries they have on those cars, we've done a simulation using data from a co-operation partner of ours, and we've analyzed it. When you combine our technology with the lithium battery, we could reduce the size and weight of the battery pack from 300 kg (661 lb) to about 200 kg (441 lb) – and you'd have a longer driving distance as well, because we're much more efficient."..............snip

Some of that doesn't make sense. Especially with regards to the regen braking. Rapid charging can provide in excess of 100kW straight into the battery so there's hardly a lack of charging capacity when needed.

The only time this wouldn't be enough is if you needed to emergency brake... If electric vehicles are currently dumping excess regen braking energy as heat, within the drive train/charging electronics, this is a problem with the electronics, not the batteries ability to accept charge.

I mean the P100D draws about 400kW for the 2.5 seconds it takes to get to 60. With friction losses assisting with the braking, shoving 100kW per second, back into the batteries, should get the car to stop in ~10 seconds. I don't see the problem.
