When I first saw this I just couldn't help but assume its a new vaporware grabbing headline with a bunch of nerds just getting a little too excited about stuff that will be impossible to mass produce etc...aaronlim said:

But turns out the guy behind all this is the father of the lithium ion battery 30 years ago..
NTU professor Rachid Yazami, the co-inventor of the lithium-graphite anode 30 years ago that is used in today’s lithium-ion batteries, said Prof Chen’s invention is the next big leap in battery technology.
http://en.wikipedia.org/wiki/Rachid_Yazami
Rachid Yazami is a scientist best known for his research on lithium ion batteries and on Fluoride Ion Batteries. He is the inventor of the graphite anode (negative pole) of lithium ion batteries.
So while i hope to see something in 5 years it seems very real to me.

Well, let's get some of their batteries from 1994 and test them. If they don't HAVE any from 1994, that claim is at least suspect.
The argument is pessimistic but correct... Accelerated ageing is a best guess as to the probable effects of time and is often wrong. The only real (but often impractical) proof of a calendar life claim is testing over an equal period of time. Anything else is a "predicted" or "expected" service life.
70% in two minutes has to be around 30C.

Here is another article regarding the 70% charge in two minutes. http://powerelectronics.com/blog/ul...article_6&YM_RID=CPG05000002102275&YM_MID=373 They claim the material that allows this to work is extremely abundant and inexpensive. They also state it has been licensed to a company already in preparation for production. I will be very interested to see additional details regarding cells made using this technology. They always seem to leave out one or more important points that ultimately make the technology not feasible or as great as initially claimed. I guess we will need to wait another 6 months to see if it goes further. This would definitely remove one stumbling block to wide spread EV vehicle implementation. The next one is capacity! In 20 years most of us will be driving or be driven by electric vehicles.

Edit:
According to their website, http://www.solidenergysystems.com/updates.html, they claim to have a verified volumetric energy density of 1337 Wh/L.
If their assertion about 2X current lithium energy density is true then we should be talking about a gravimetric energy density of 600 watt-hours per kg.

Keep in mind, the first lithium cells were metallic lithium based. It's been done by at least 2-3 new startups a year that proudly re-discover that metallic lithium offers extremely high energy density.
They all struggle for a bit and then also realize that designs using metallic Lithium are pretty unlikely to meet bare minimum safety and cycling requirements to be useful for non-disposable battery applications.
These cars have been on the road since 2005 with lithium metal polymer batteries:
http://en.wikipedia.org/wiki/Bollor%C3%A9_Bluecar
Their batteries suck because they have to be heated but don't you ever wonder what happened to Kolibri Energy who also had a lithium metal cell? Oh yeah that's right they were bought out by middle east investors after a mysterious fire.....
-----------------
Remember the controversial 2010 Audi A2 converted by German battery firm DBM Energy?
The car hit the headlines last year when it apparently travelled 375 miles on a single charge. Powered by the latest battery technology, the car’s creators even claimed a 6 minute recharge time.
But before any official tests were carried out on the car or the battery pack to back up the seemingly outlandish claims, the car was mysteriously destroyed in a warehouse fire.
Luckily, the ‘wonder battery’ - a Kolibri alpha-polymer battery pack was not present in the vehicle during the fire, and has been put through its paces at the hands of Dekra, an independent testing organization which works heavily with the automotive industry in Germany.
According to a press release from DBM energy, testers at Dekra ran a converted A2 similar to the one destroyed at the DBM warehouse on a chassis dynamometer and were able to drive the car for a simulated 283 miles on a single charge
But the tests are hardly unexpected. The DBM Kolibri Lithium-metal polmer battery pack used in the tests had a capacity of 63 kilowatt-hours, making it a little over 12% bigger than the Lithium-ion battery pack found in the 2011 Tesla Roadster.
On a full charge, the 2011 Tesla Roadster has an EPA approved range of 245 miles. The 12% bigger battery pack of the DBM converted A2 produced just over 15% increase in range.
Missing Miles?
The observant reader may note that there is a deficit of 92 miles between the claimed range of the original record-breaking DBM Energy A2 and the one tested by Dekra.
You’re right. However, the since-destroyed original vehicle included a 115 kilowatt-hour pack, more than accounting for the deficit in miles.
Accounting for the added weight a 115 kilowatt-hour pack would bring, the initial 375 mile claim looks plausible.

283 is more than the Model S was able to achieve at Dekra

Holding the energy has never been the reason we don't see metallic lithium cells used in much of anything non-disposable.
Safety and cycling have been the classic stumbling blocks of the metallic lithium based designs. Making a pack that holds a ton of energy has never been the concern for the metallic anode based cells, they had excellent energy density even in the early 1980s.

The world’s first ever storage technology, whose extremely high performance figures do not entail danger. Absolutely safe, under extreme climatic and air pressure, on electrical short-circuits, overloading, wrong polarity, strong mechanical stresses such as vibrations, impact, crash as well as on underfiring or contact with water. Successfully tested and certified by the Federal Office for Material Research and Testing.
Berlin, Germany - 1 April 2011 - For over a year KOLIBRI batteries run by DBM Energy reliability in the application of electric commercial vehicles and logistics. In the framework of a Federal Ministry of Economics and Technology Demonstration Project was required with this innovative battery technology in October 2010 set up with an electric vehicle is a long-distance world record with over 600 km range. The endurance of the technology, let KOLIBRI apparent in 5000 charging cycles. Independent studies now confirm the safety and perform better the KOLIBRI technology.

On 17 January 2011 started the BAM Federal Institute for Materials Research and examination, an extensive testing program for the audit of the safety of the novel technology of DBM KOLIBRI Energy. The recently completed studies have shown the single cells that, as a demonstration ride on 26 October 2010 KOLIBRI technology used, the necessary safety standards on air, land and water satisfied.
Basis of safety investigations is the UN for carriage of dangerous Prüfhandbuch Good. The Prüfmethoden for lithium batteries are recognized as a standard. Effort in test series was to investigate whether the KOLIBRI safe technology for extreme climate and air pressure changes, electrical Kurzschlüssen, Überladung or polarity, as well as strong mechanical influence such as vibration, shock and impact is. The cells of the DBM KOLIBRI Energy have all passed the exam.
"The tested KOLIBRI cells are characterized by a high degree of technical safety," Prof. Dr. Schroder erläutert the results of several repeated tests. All in the UN Prüfserie requirements could meet KOLIBRI cells. The cells were not leaky at the appropriate tests have not been warmed above 170 degrees Celsius, not broken or inflamed, and held more than 90 percent of the voltage.
Addition to the UN Prüfkriterien KOLIBRI the cells were examined for Brandgefährlichkeit. In the underfiring turned out to the cells as KOLIBRI explosion proof and not an accelerant. Conclusion of Prof. Dr. Schroder, of the BAM: "Overall, we can and estimate that the cells KOLIBRI the safety requirements that must be made with such technology, fully satisfy."

Fortunately, since then more deposits were searched for and found (wikipedia):

I still want to know whats up with Kolibri

Not really a problem, but I believe the lithium-titanate based cells only put out ~2.2v/cell. Should still have really great energy density though, even in this ridiculously power dense design.
megacycle said:
That's the real problem. These articles say junk like "Electric cars take 4 to 5 hours to charge! Because batteries!" When really, 2. to .25c charge rates are a result of the charging system limits, not the pack. 1c or .5c are realistic for a lot of cells out there.
Not to mention that line about how normal batteries need to be actively cooled so they don't catch on fire. I mean what the hell?! A gas engine seems much more likely to catch on fire than an electric battery, unless perhaps you're using LiPo without a BMS in an insulated box in Arizona.

Many cells you could get away with 5 min/12C charge, like A123, pouch, just having the charging facilities, even for say a 1.5kWh ebike pack, pumping 240A@80V out, is some ask for a home charger.xenodius said:
Hey you can pump more I to them when they're warmxenodius said:

It's either a several minute charge for cars at supercharge stations, or I think the flow cell tanks will come, they will be a practical solution to fill tanks instead.
