Do you remember Stanford scientist Yi Cui silicon nanowire anodes?

Well it looks like LG thinks that they might have a commercial product within 3 years..

Researchers at Stanford University and Hanyang University in Ansan, Korea, are developing the nanotube electrodes in collaboration with LG Chem, a Korean company that makes lithium-ion batteries, including those used in the Chevy Volt. When such a battery is charged, lithium ions move from the cathode to the anode. The new battery electrodes, described online in the journal Nano Letters, are anodes and can store much more energy than conventional graphite electrodes because they absorb much more lithium when the battery is charged.
The silicon nanotubes are made by repeatedly immersing an aluminum template in a silicon solution, and then heating it and etching the structure in acid to remove the aluminum. "It's very simple, and the template is commercially available," says Cho. Along with LG Chem, Cho is working with the template manufacturer to make a template compatible with large-scale manufacturing. He believes batteries incorporating the nanotube electrodes could be on the market in three years.

LG Chem is just a subsidiary of the LG Group, South Korea's third largest conglomerate, with revenues of $104.3 billion in 2008, and 177,000 employees.

Even if this battery is a home run, the effect on LG Group stock will be minuscule, and will probably be swamped by other factors.

A123 Systems is a pure-play lithium battery supplier, on the cusp of the Electric Car Age. The company has only 1,800 employees and is headquartered in Watertown, Massachusetts. They also use nano-scale engineering for their electrodes - perhaps LG Chem has a better manufacturing process, but the li-ion battery game is just getting started.
A123 Systems is a privately held company, so you can't buy or sell their stock anyway.

On August 2008, the Company filed a registration statement for a proposed initial public offering with the Securities and Exchange Commission.
On January 2009, announced that it has submitted an application under the U.S. Department of Energy's Advanced Technology Vehicles Manufacturing Loan Program (ATVMLP) to qualify for US $1.84 billion in direct loans to support the construction of new lithium ion battery manufacturing facilities in the United States, with the first construction location in southeast Michigan.
In April 2009, Chrysler LLC announced a contract with A123 to supply batteries to their Envi (automobile) batteries.

I guess there's just no way that ol' Dr. Cho, a supposed American, working in and funded by an American institution, could possibly supply his technology to an American company? Nope. For sale to the highest bidder. This country is doomed I fear.:(

Looks like the great battery race is shaping out to be exactly like DRAM, NAND Flash, and flatscreen war before it; Koreans vanquished competition by outspending the competition in the chicken game.

You will not get a 10x jump in one shot, this will be incremental.

I doubt it will be in 3 years.. btw, this is only half the battery that can perform 10 times better (the cathode?), you still have to improve the other half or you will not notice any improvements.

Yeah, it's good to bring up incidents to get people all fired up. Should we also bring up all of the other atrocities that happened by one countries' citizens to another? What about all the atrocities that happen every day by one countries' citizens to their own citizens?

Humans can and do amazingly horrible acts both in war and out. Do we change foreign policy drastically because of one act of craziness by a group of crazy individuals? I guess that's the question.

Do you change the way you vote because one religious radical commits a horrendous crime against nature? If so, does that not give them more power (like what happened in Spain - bomb a train, change the elections).

Not that I'm for having American bases all over the world at a cost that’s so high it's crushing our own financial health. I’m against it. However, If countries drastically change their course because of isolated craziness we are all in for a wild ride.

The best we can do is work together, make agreements, work on our relationships between nations and try as hard as we can to keep things stable. Will there be conflicts? Of course. It’s human nature. Can those conflicts be contained so they don't lead to world war? They must be contained.

I think the world learned a good lesson over the past 8 years. We don't want to have foreign policy like that. Harsh, isolating, filled with conflict and suspicion, dogmatic and self righteous. Dropping bombs at a moment's notice.

I guess you're right.
We should have let 9/11 slide. Heck, less than 3000 people died that day, that's less than 24 days of traffic fatalities in America. And buildings, they can always be rebuilt.
And atrocities of Americans on Americans ? 15,586 were murdered in 2000 by other Americans, that's more than 5 times what the Saudi hijackers did on 9/11/01.

We shouldn't have changed our foreign policy over just another day of craziness. Getting emotional just made everything worse... we should learn from the Japanese leaders, who stoically overlook every schoolgirl rape, no matter what their emotional peasants do:

Totally agree. Volume is not an issue so much as weight is for EV and transportation applications. In any case, weight and volume are pretty much the same measure - in that an improvement in energy specific weight in a certain technology also generally improves the energy density.

The reason the Volt does not have a 5th seat is because GM adapted an existing ICE platform to use the T-Pack.. perhaps also because they had lots of engineering experience with the huge T-Pack used in the EV1. That truly was a big pack.

We are seeing a lot of new pure BEVs that use a flat thin rectangular pack just below the floorboards (5 seat cars), true that these are BEV that do not have to deal with routing an ICE exhaust system, but how hard can that be?.. just move the battery a bit to the right, offsetting the weight of the driver a bit in the process.

I really hate that huge tunnel in a compact car.. it means you cant spread your legs open to be fully comfortable... of course women dont have that problem :)

Looking forward to the pure BEVs coming soon to the market.

This one is my favorite so far, so cute!

Note how efficiently the space inside the cabin is managed:

PDT, I read somewhere that there is lots of empty room inside the Volts T-Pack..
