How spectacularly do they burst into flames?

[Red Badger]

Hopefully they solved that little problem............

Don't worry in a year all the mac-bots will claim Apple invented it

One of my gnomes attended a rubber-chicken auto diner / conference with a big kahuna in auto media world who was on the dais.

Discussed was that batteries longevity will double, amongst other things. This is in line with the doubling point...

Interesting

Apparently their is a version of LI-ion's that use phosphate as part of the chemical mixture and they don't do the thermal run-a-way thing. I think race car and homebuilt airplane guys have found them and are trying them as the weight reduction vs. even a small lead-acid battery. The weight savings is a great deal. Something like a 3 lb battery will start a 150hp engine...

Maybe Moore’s Law applies to batteries, as well.................

[Steely Tom]

The best energy density of a conventional lithium-ion battery is somewhere around 2 MJ/L (megajoules per liter). If we believe the information given in this article, that means that Samsung's new batteries are around 3.6 MJ/L, at least when they're brand new.

For comparison, the energy density of gasoline is around 32 MJ/L, which is not quite nine times as much.

Of course, to turn gasoline into electricity requires heavy, bulky, noisy rotating equipment that weighs a lot, is dirty, vibrates, and ejects red-hot poison gas. A battery requires none of that.

"but the fly in the ointment is the graphene—despite a lot of time, effort and money invested, scientists still have not figured out a way to manufacture the stuff in bulk, which means, that the new battery design will not be available to consumers until a way can be found to produce the graphene."

[HandyDandy]

That's because "Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points. The Dirac points are six locations in momentum space, on the edge of the Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K'. The sets give graphene a valley degeneracy of gv = 2. By contrast, for traditional semiconductors the primary point of interest is generally Γ, where momentum is zero. Four electronic properties separate it from other condensed matter systems."

Re: battery doubling - Moores law

Hoping we’re just about there.
Huge battery breakthroughs currently in play.
New battery company M24 is attracting big investment and may make Tesla regret their decision to go with a multi Billion dollar battery plant.

Thanks for the link, I will read later. Are you aware of the Israeli / Alcoa Aluminum Battery and Amy Prieto CSU Battery?

Would this be a doubling of the Tesla battery life (250 miles) or volt battery life (100 miles)

[MarchonDC09122009]

You’re welcome.
Yes, I’ve been following those battery developments, too.

Once cost-effective, durable, safe, lightweight batteries arrive, it will make personal defense laser diode array weaponry all the more practical!

[RayChuang88]

They better hurry it up because several Chinese companies are seriously looking at a new generation of dry-electrode lithium-ion batteries that could effectively triple the battery life per charge on a battery pack about the size of the one used on the iPhone 6. It would be like running an iPhone 6 with a Mophie Juice Pack battery case but without the need for that extra battery.

[Red Badger]

I wonder, have they considered lead as an electrode?...........

Graphene ping.
