US Corps Want $1B From Gov't For Battery Factory
tristanreid writes "The Wall Street Journal reports that a consortium of 14 US technology companies will ask the Federal Government for up to $1 billion for a plant to make advanced battery technology, as a part of the broad fiscal stimulus package that Pres. Elect Obama is planning. The story quotes a report by Ralph Brodd, which suggests that while existing battery technology was developed in the US, the lead in development is now held in Asia. From the WSJ story: 'More than four dozen advanced battery factories are being built in China but none, currently, in the US.'"
Besides, battery technology is not the most effective way to power cars. They are too volatile, have too short a life expectancy, and produce too much nasty chemical waste (both during manufacture and disposal).
False.
1) I don't know what you mean by "volatile", but if you mean "catching fire", that's mainly just a problem for traditional li-ion. The phosphates, titanates, and stabilized spinels don't do that because they don't get lithium metal plating and the like. The worst you can say for the advanced li-ion cells is that the electrolyte is often flammable, and that if you had both a puncture and a spark (puncture alone won't cut it), you could get fire. But you know what? So is gasoline. At least the electrolyte is isolated into a bunch of small containers that would, worst case, fail individually.
2) The life expectancy notion is way off. Let's start by busting the basic premise -- that all batteries inherently have to have short lifespans. Jay Leno's early-20th century Baker Electric still runs on its original nickel-iron batteries. Decade-old RAV4EVs are still running fine on their original NiMH packs despite heavy usage. It's simply a myth that there's something inherently about being a battery that means you must have a short lifespan; it all depends on the chemistry. And getting to the advanced li-ion types being looked at -- the various olivine and spinel cathodes and titanate anodes -- they're incredibly stable. Assuming you keep the temperature in the packs from getting ridiculously hot, you're good for the lifespan of the car. A123 and Valence's LiPs, for example, are good for about 7,000 cycles at 1C before losing 20% capacity. AltairNano's titanates take tens of thousands of cycles to lose that much.
3) What nasty chemicals do you think are involved here? The worst you can say is that the titanates, like traditional li-ion, have a LiCoO2 cathode. But that's only mildly toxic. Phosphates and spinels, you can literally throw straight into the trash in some places. The worst thing in them is that the electrolyte is corrosive. Manufacture is no worse. Phosphates, for example, traditionally have their cathodes made from phosphoric acid, iron powder, and lithium carbonate, with a carbon binding from burning sugar. The anodes are just graphite. The separator is just plastic.

Lithium is not a "nasty substance", and it's not found in raw form, either in production or in the batteries, anyways (they use lithium salts, like lithium carbonate, a common red colorant in fireworks, for that). Try again.
