The problem is I don't think anyone is even meeting the normal A123's max discharge rate, and I'm pretty sure nobody is even hitting their 4C charge rate. If we were, we'd be fully charging our packs in 15 minutes. But we're all using multiple cells in parallel and charging them at only 2-5 amps usually, so that's like 0.25C.

For some reason I'm visualizing a bms that is twice the size of the battery. But maybe you could have that be part of the charging station. It would take a good one to charge at that rate and not explode the battery before it could shut off. Maybe the car could tell the charger how much it needed to get to an 80% charge, and then just run that much in? After some getting used to, I think a 30 minuite charge would be somthing most people could live with, especially if it could be down where you are eating lunch, or shopping for a few minuites.

thanks toshi for the paper. i almost wanna email the author and ask him to post up the supplements here. this is so remarkably simple and well conceptualized principal that i feel their claims of producing superior energy density to super capacitors is entirely justified.
i learned a lot from reading it which i had only halfway understood, if anybody else is kinda academically interested we could yak about the experiment here.
in simplest terms, they had this idea that 'smoothing' the surface of the nanocrystals which make up the cathode matrix by creating an amorphous 'glassy' surface would allow the lithium ions to skip across it easily in order to reach the 010 orientation in the crystal, where it can easily enter then into the openings in the crystal where it is intercalated to allow the electron to flow the other way through the bulk material of the cathode.
what they did was take 'off stoichiometry' amounts of iron and phosphorus when mixing the lifepo4 to be sintered. when the cathodic material reached a high enuff temp, there is phase separation of the phoshorus rich glassy materials from the crystalline lifepo4. then the surface became amorphous (non crystalline) even though the bulk is crystalline lifepo4, and the phosphorus rich amorphous material still had some iron but not bound into a lip2o7 crystal(as i remember), so the amorphous surface did not interfere with the movement of the lithium ions to the 010 orientation in the crystal where it could penetrate into the bulk. and the sweet part is that this amorphous structure is very conductive too and not a strong insulator, by comparison to the bulk crystalline lifepo4 which is only marginally conductive itself. that means the current can be carried easily out of the bulk and through contact with other crystalline cathodic granules in the matrix.
the xray spectroscopy shows the big lines for the lifepo4 and where the other crystals appear as the sintering temp is raised and the materials separate. the mossbauer spectroscopy is a technique for determining the forces holding the iron in the crystal, which tells them what the iron compound may be, in this case an iron phosphide. you can use a radioactive isotope of iron called iron 57, which has a gamma ray decay often enuff that you can use it experimentally to determine the frequency of the oscillation of the iron in the lattice, and from that the inter atomic forces. different crystalline structures of the iron have different inter atomic bond energies which can be measured using the 'zero phonon' rebound of the lattice when the gamma ray is released. i used iron 57 for the source when i did my thesis using mossbauer spectroscopy to estimate the force constants in crystalline iridium, rhodium, and Be, 30 years ago now.
this was a very elegant idea, and i think is right up there with the stanford paper on silicon nanowires.
to reach the high currents, they had to use an excess of carbon in their little swagelock cell, so they could conduct the current, and they talked about how that was what limited the energy density, but a problem which disappears with the silicon nanowires for the anode. the great thing about silicon nanowires is that they can be doped to increase conductivity. when making semiconductors you are always fighting to keep the silicon from getting doped unless you want it to conduct as in the drain and source. so once chiu can get his work into a manufacturable anode, and this cathode material can be created with the amorphous surface and repeatably, we should have cells with at least 10 times the currently available discharge and charge profiles. maybe 4-5 years at most. not including newer electrolyte formulations which could appear, or other ideas along this direction not yet published.
what we worry about as internal resistance is really a diffusion problem for the electrolyte, carrying the li ion through the separator to the crystalline cathodic material and into the bulk of the crystal, and this treatment just increases the mobility of the li ion when it reaches the surface of the crystal so it gets 'sucked' into the crystalline bulk through the 010 orientation rather than 'hanging up' on the other crystalline facets of lifepo4 on the surface of the nanocrystal, because there are none, it is all amorphous on the surface.

Cool, except that the plug for that fast a charge will get a bit heavy, as will the other end in the car. So charge time won't be 90 seconds unless you want to tote around a 200 pound receptacle.

Hi,
That might be a better bet for Ebikes.
So right now "Toshiba now makes 150,000 SCiBs a month" and we can't buy them.
So the bottom linie is that this fall they will be producing about 15x as many batteries of superior quality and we probably won't be able to buy those either

Cheer up - 150,000 a month probably doesn't cover their laptops or MID's or whatever Toshiba product they are putting them in. They just got burned by a recall of Sony laptop batteries that caught fire (no pun intended - it just happened) and are using their own that they trust. Toshiba products have been bullet proof in my experience - my laptops are still running and go obsolete before they quit. If they will ramp up production we will be able to buy them and may be able to do so shortly as they come up as replacement parts for whatever they are in. I will search the Toshiba sites and see if they show up on a parts list somewhere. It is hard to think of a more expensive way to buy a device than as a replacement part for a consumer electronics product...

Hi,
Their current batteries are being used or slated to be used in Ebikes:

I doubt you can buy them and if you can I bet the price is obnoxiously high.

The batteries are from Altairnano.
Nominal voltage 2.3V. Not as energy dense as LiFePO4.
They have some fact sheets for their 11Ah and 50Ah batteries on the web site.
Great batteries, but I think the company is more interested in stationary power applications these days.

Altair Nanotechnologies Ships Batteries to the U.S. Army
On Wednesday April 22, 2009, 7:30 am EDT
RENO, NV--(MARKET WIRE)--Apr 22, 2009 -- Altair Nanotechnologies Inc. (Altairnano) (NasdaqCM:ALTI - News), a leading provider of energy storage systems for clean, efficient power and energy management, announced today the shipment of 40 advanced battery systems in support of the Army's M119 105mm lightweight gun digitization program.
The battery development initiative, announced by Altairnano in August 2008, is part of a military testing program to demonstrate the use of Altairnano's advanced battery systems for improving performance, reliability, and safety attributes associated with M119 105mm gun batteries. Jim Shields, the Army's program manager indicated, "I am very excited about the capability offered by the Altairnano battery technology and look forward to conducting system level testing and delivering leap-ahead performance to our troops."
"Altairnano's advanced battery systems exhibit the widest operating temperature ranges and highest abuse tolerance of any lithium-ion battery available today," said Terry Copeland, president and CEO, Altairnano. "The projected long-life of the batteries is also an important attribute, which is expected to help the military replace batteries less often than shorter-lived, conventional lithium-ion batteries."
Engineering and software design for the M119 gun digitization program is being managed by the Armaments Research Development and Engineering Center (ARDEC) at Picatinny Arsenal, New Jersey. Testing of the recently shipped battery systems by the U.S. Army's Communications and Electronics Research, Engineering and Development Command (CERDEC) at Ft Monmouth, New Jersey is expected to continue through summer 2009. Once approved for the M119 105mm lightweight gun digitization program, the Altairnano battery systems could be offered for use throughout the military's M119 105mm inventory, which currently numbers around 850 howitzers.
The system designed for the U.S. Army features a 24 Volt/22 Amp Hour battery with an integrated battery management system (BMS). The battery has broad applications beyond the M119 program and could extend to other weapons platforms, advanced military vehicle designs, portable power and back-up power applications.

Is this the magic lithium?"Upto 100C continuous with 250C burst" +
"80% of initial capacity remaining at 5000 cycles of 100% DOD" (Upto 500,000 with shallow discharge)
And it looks like it has the discharge characteristics of some type of lithium-manganese or cobalt. What makes these cells special? Could it be that it's lithium titanate?
Edit: I read the document and apparently it's called "Ltihium Nickel Oxide". Is nickel... abundant?
Apparently, lithium nickel oxide has been hotly pursued for the past few years for Hybrid applications. http://www.futurepundit.com/archives/003286.html
Holy crap, lithium technology sure seems to be the wave of the future (Not that it already isn't, but...).
