Press release:
HENRIK FISKER RELAUNCHES FISKER INC. http://www.fiskerinc.com/s/Fisker-Inc-Press-Release.pdf

Bloomberg article:
Henrik Fisker Is Starting a Namesake Car Company Again http://www.bloomberg.com/news/articles/2016-10-04/henrik-fisker-is-starting-a-namesake-car-company-again
“We have really been working in stealth mode,” Fisker said. “For the last two years, I have been looking at battery technologies and wanted to see if there was something that could really give us a new paradigm. We had the strategy of developing the technology as fast as possible without getting tied down to a large organization, which would hold us back. Now we have the technology that nobody else has. And there is nobody even close to what we are doing out there.”

The designer credited with creating the BMW Z8, Aston Martin V8 Vantage, and Aston Martin DB9 saw his Fisker Automotive Inc. go through a structured bankruptcy auction in February 2014, where Wanxiang Group bought certain assets, excluding the Fisker brand. Fisker, Inc. is Henrik Fisker’s new entity and Fisker Nanotech is its battery division, a new private corporation based in northern California. Fisker is the chairman and chief executive officer of Fisker Inc; Jack Kavanaugh is the chairman of Fisker Nanotech.

Details about the new car—and specifically, the new technology—remain scarce. Kavanaugh said he hopes they will achieve unparalleled range and battery life, thanks in part to a new packaging method and to lightweight materials in the battery pack.

“The technology emanates from several professors from UCLA who have been working on energy storage,” Kavanaugh said, noting that the batteries will contain some lithium but not be the conventional lithium-ion batteries found in such things as the Tesla Model S. “We have already developed prototypes that you won’t see anywhere else.”

The team claims that the new Fisker model, which has yet to be named, will deliver more than 400 miles in driving range and possess an industry-leading battery life that will potentially match the life of the vehicle. The plan is to develop it at Fisker Nanotech's prototype-and-manufacturing facilities in California, Kavanaguh said. It will feature more rear legroom and headroom than any of its closest competitors.

Fisker, who lives in Los Angeles, said the ultimate goal of creating the new battery technology is to sell it to an OEM (original equipment manufacturer). The idea is to move the entire auto industry, as it were, from VHS to DVD mode, he said.

“Fisker will be doing all of the testing, and that gives us a huge advantage, but that doesn’t mean we will be sitting on [the technology] alone,” he said. “We will also be looking at selling this technology to other OEMs because if you want to reach true mass-market potential, we need probably, eventually, an OEM. We are having very superficial discussions right now with a couple of them.”

Something very interesting I found out, which is not mentioned in the press release or Bloomberg article is that Fisker Naotech's chairman Jack Kavanaugh is also the a founder, chairman and CEO of Nanotech Energy Inc., a UCLA spin-off researching in graphene supercapacitors: http://www.nanotechenergy.com
Jack Kavanaugh's LinkedIn profile: https://www.linkedin.com/in/jack-kavanaugh-a534337
It's not unlikely that the Fisker Nanotech graphene batteries will be a combination of the Nanotech Energy graphene supercapacitors and lithium-ion batteries.
 
"Sponges hold the key to the batteries of the future"
("A new energy storage device developed by MIT researchers that uses sponge-like structures could outstrip the current carbon-based tech.")
https://www.cnet.com/news/sponges-hold-the-key-to-the-batteries-of-the-future/

MIT researchers have for the first time developed conductive metal-organic frameworks. Don't close the tab just yet, because these MOFs (Ed: Modified Metal Organic Framework) could be at the heart of the next generation of battery technology in power grids and electric cars.

Current supercapacitors rely on carbon, which requires high temperatures and harsh chemicals to produce. The sponge-like structure of MOFs offers far more surface area, which is a key component in producing supercapacitors but the challenge was in making the material conductive.

"Our lab's discovery of highly electrically conductive MOFs opened up a whole new category of applications," said Mircea Dincă, an MIT associate professor of chemistry and one of the co-writers of the paper.

Even without optimisation, the new tech matched or exceeded the current carbon supercapacitors in key performance areas.

The team says supercapacitors are able to store comparatively large amounts of power and could "play an important role in making renewable energy sources practical for widespread deployment," reads the release. The team's findings will be published in the journal Nature Materials.

Startups with novel chemistries tend to falter before they reach full production.

There were a few mistakes in that article about failing battery companies. Auto makers need a few years of proof testing in order to invest... That's why a new battery company should invest in a little lipo plant that makes batteries for drones and RC. If you are going to give a phantom DJI 150% improvement on flight time, you would have a famous and renouned brand name right from the start... INVEST 500 MILLION??? in a battery company? that's totally unreasonable. It's the entire investor "white elephant" ethos of investing half a billion in a new technology, that makes companies like A123.

Those battery companies, they are intellectual property companies too. If they find the best designs for new batteries, they can keep the patents for them, the most productive labs make money. Most of the designs for new batteries can't compete with 90 percent of the other new technologies for price and performance. that's why 90 percent of the startups fail. In china you can make a battery company for less than 5 million and then it is just subject to market performance. why 500 million. best to let small brand become a big one by it's merits.



Julia Louis-Dreyfus Does Commercial For Battery-Operated Mercedes AA Class Car On ‘SNL’
Interest in electric cars has increased a lot since 10 years, and the interest will only grow as batteries improve, Wh/cm3 has doubled between 2000 and 2016, and will probably jump a lot by 2020. Mercedes won't stop electric cars being more and more popular.
Mercedes is competing with BMW which has a lot of evehicle research.

I agree with that idea as well.
Lets say I made a method to mass produce one of the newer battery advances.
I would spend my first 6 months making sure I made good, safe cells without production issues. Maybe as long as a year.
I would take these hand-tested cells, and hand them out to OEMs. Not just current car companies, but e-motorcycle companies, cell phone companies, portable electronics, etc.
Once production quality has been confirmed, I would start a second company for liability reasons, that specializes in RC and hobby packs. RC would be small but have a huge volume of consumers, some Hobby would be more EV oriented with far fewer orders, but most orders would be larger.... and other hobby would be much smaller batteries for places like Sparkfun and such.. basically the RC packs but not in packs.

The company can then self-sustain with that income while waiting for the OEMs to make production orders.

"Bendable Battery May Power Future Wearable Devices, Smartphones":
http://www.livescience.com/56514-be...er&utm_medium=email&utm_campaign=20161019-lst

panasonic-bendable-battery.jpg


A new bendable lithium-ion battery that can flex and twist could power wearable devices and one day be used to develop a flexible smartphone, according to Panasonic, which is developing the new battery.

Although it's still in the early stages of development, the battery already has been tested to withstand twists, bends and other deformations while maintaining its ability to hold a charge, according to Panasonic. In contrast, a regular lithium-ion battery, commonly used in smartphones and other gadgets, can degrade when it is deformed, thus shortening the device's operating time, the company said.

The battery was unveiled earlier this month during the annual Combined Exhibition of Advanced Technologies (CEATEC), a technology fair held from Oct. 4 to Oct. 7 in Japan. [10 Technologies That Will Transform Your Life]

Lithium-ion batteries can be highly volatile if they malfunction, as was the case with the Samsung Galaxy Note 7, which was plagued by battery problems that caused them to overheat and sometimes explode. Faulty batteries can catch fire when they are overcharged, because the lithium ions can collect in one spot and be deposited as metallic lithium. If this happens, the heat from the overcharging can cause oxygen bubbles to form, which are highly reactive with metallic lithium. If they combine, this can lead to an explosion.

Panasonic's bendable battery uses "a newly developed laminated outer body and internal structure" that the company said makes it difficult for the battery to leak or overheat. With this new casing and internal wiring, the battery is both safer and more reliable for wearable tech devices, the company said.

The bendable battery is just 0.02 inches (0.55 millimeters) thick, and was able to withstand being bent so that the curve of the battery has a radius of 25mm, and being twisted up to 25 degrees in tests, according to Panasonic. The company noted that the capacity of these batteries is still small — they can hold a charge between 17.5 mAh (for the smallest size) and 60 mAh (for the largest). For comparison, the iPhone 7 has a 1,960-mAh battery. Though further development is needed before the battery will be ready for use in smartphones, the invention could be suitable for low-power devices such as smart cards or smart clothing, Panasonic said.

"When used in card devices such as smart cards and card keys that work on batteries, as well as body-worn devices and smart clothing, this battery can retain its characteristics even if the device is frequently bent or twisted," the company said in a statement.

Though samples of the battery were on display at the conference and sample shipments are scheduled for the end of the month, Panasonic said mass production will require further product development.

I'm kinda interested in flexible/bendable (watt exactly IS the difference? Must check.) battery cells to paper the skin/shell of a "velomobile"-style recumbent trike. (Think eg warm/dry cabin in the cooler and winter months.) ;)

LOL @ journalists


This is the equivalent of claiming to know why some gas car burned, because someone explained to you if you were to take a car, rip open the fuel tank and drop a lit-road flare into it could burn up.

Strangely enough, if you were to rip open a fuel tank and drop a road flare into it, theres also a good chance that it would not ignite the fuel vapor, but go out when it hit the liquid gasoline.

That said.. yes. the article was crazy-talk. lol. Atleast everyone forgot about the chinese lithium hoverboard incidents.

One more. "Tesla Brings New Technology to E-Bike Batteries"
http://www.bike-eu.com/sales-trends...s-new-technology-to-e-bike-batteries-10127994

HSINCHU, Taiwan – It sounds like a fairy tale; e-bike batteries that last as long as the e-bike itself. A lifetime of over ten years is within reach. New cell technology also brings batteries capable of much more pedal-supported mileage. And it already comes in 2018. All this is thanks to Tesla.

That Tesla is behind revolutionized batteries for electric bicycles has all to do with the recent changes at the leading battery cell makers Panasonic, Sony, Samsung and LG. Together these four make out some 80% of the world production of battery cells.

Like penlight batteries

These cells are like penlight batteries commonly used in every household. When connected lots of these cylindrical shaped cells make an e-bike battery when of course integrated technology is added like a Battery Management System (BMS).

Changes at IT industry

The mentioned four cell makers used to supply huge numbers of cylindrical shaped cells to the IT industry. However, this industry changed completely from using cylindrical shaped cells to flat shaped batteries which are now used in laptops, tablets and smartphones. A small part of that lost sales was compensated by batteries for e-bikes and other Light Electric Vehicles. However, that sales was too small for Panasonic, Sony, Samsung and LG to invest in the development of new cell technology.

Tesla placing huge orders

Until Tesla knocked on their doors placing huge orders for cylindrical shaped cells. It is in particular Tesla’s newest Model 3 e-car that pushed battery cell makers to new highs. This affordable e-car (retailing for about 35,000 USD) needed a much extended range at smaller dimensions and weight. This called for new technology. At first the battery cell makers were able to add capacity to the currently commonly used 18650 cells. According to GM Mo-Hua Yang of Taiwan based battery maker HiTech Energy, two years ago such a 18650 had a capacity of 2.2Ah. Now it stands at 3.5Ah. More capacity however called for a new cell.

New 21700 battery cell

At Eurobike of last September that new 21700 battery cell appeared on the horizon. No not as a bright light that catched everybody’s attention. This new phenomena wasn’t even on display. It was only mentioned in a press release by BMZ which is Europe’s largest battery maker. BMZ boss Sven Bauer explained to Bike Europe the revolution this new cell will bring to electric bicycles. In particular as the 21700 cell not only offers a much prolonged lifetime but also batteries with a much bigger capacity for more power and pedal-supported mileage.
New standard in e-bike batteries

BMZ is not the only battery maker convinced of the extraordinary features the 21700 battery cell brings to e-bikes. Taiwan based HiTech Energy even says that it will be the new standard in e-bike batteries. And that this new standard will already be there in 2018. So, what’s 21700?

Bigger size; bigger output

It’s a cell of a new format: instead of a 18650 (18mm diameter and 65mm high) cell size the 21700 cell is 21mm diameter and 70mm high. The bigger size is bringing a bigger output; up to 4.8Ah. With that capacity the battery lifetime is extended from the current some 500 charging cycles up to 1,500 to 2,000 cycles.
Less charging, prolonged lifetime

These up to 2,000 charging cycles forms the basis for a much prolonged lifetime. In particular as recharging kills batteries, states BMZ MD Bauer. “As there is less need to constantly re-charge batteries the 21700 cells offer a much increased battery life.”
New standard in 2018

GM Mo-Hua Yang of Taiwan based battery maker HiTech Energy says the same on e-bike batteries made with 21700 cells. But he adds that there’s also another much needed factor that comes into play. And this is in particular needed with rapidly increasing sales of electric Mountainbikes; batteries that can offer more power and range. Yang says, “Smaller batteries offering 1,500 to 2,000 charging cycles as well as 700Wh will be the new standard in 2018.”

Um, I don't get it.
Current maximum capacity in 18650, AFAIK, is 3.5Ah.
Just by estimating by increased diameter (21²/18.3²) and length (70/65) you get +42% capacity, which is 5.0Ah.
And they say 21700 is so great, because they can fit 4.8Ah. Is there a real increase in actual energy/power density?
This is where I don't get it.

I do see 21700s finding their place in flashlights and other portable devices, but just can't see any benefit in big battery business.

Yes, that might be it. But that will take time, as most businesses already have their designs and production sorted out. Even tiny changes can land very high costs.
Also with 18650 you get a lot of alternatives from many companies. With 21700 you won't, for quite a while.

I think its done a bit like how typical businesses do things like a new Intel CPU design, they start with a CPU clock etc no better then the old gen because they know people will buy it anyway.. then when the initial rush of buyers dies out they can actually raise CPU clocks etc and sit on barely changed microarchitecture for years to come.
Or with Apple and iPads or mac books, they just dribble out the advancements they made years ago to ensure a stable increase in revenues and net profits.
I am still on my original i7 920 2.6Ghz cpu overclocked to 4Ghz.. I can't believe this PC still works so well but until we see 5Ghz Intel cpus stock speeds I dont see any real point of upgrading.
 
I full heartedly welcome the 21700 cells. Lets hope there will be some high capacity n hi discharge Sony, Samsung and LG 21700's cells at acceptable price point within the next 12-18 months.

But if the 18650's prices keep dropping, and I can't really see why it should not they might need to up the game for the 21700 cells. Either changing the chemistry to get even faster discharge or higher capacity - if not most will probably be using 18650 cells for their packs for years to come still. I don't think the capacity alone is enough to make demand crazy.

BMZ's claims for their 21700 (Sony cell ?).....
A larger cell, with more capacity, but it weighs less ????
50% more energy
60% more capacity ?
68% increase in output ?
4 times more discharge current ?

If half those claims are true,...it will kill 18650s for EV use
