BASF to develop 350-mile e-car 'super battery' • Register Hardware

Quote:
German firm BASF and US company Sion Power have agreed to co-develop a battery technology with the potential to deliver five times the capacity of a conventional lithium-ion battery of the same size.

The battery is based on lithium-sulphur chemistry, which Sion’s been tinkering with for some time. Now it's time to take the technology and put it to practical use.

I've had my eye on Sion power for a while. If BASF can help them crack the life cycle issues, it could get very interesting.


Press release.

Press release.
As someone pointed out, even without solving the cycle issues, if they make the battery big enough it shouldn't matter too much. There's still the issue of calendar life and cost.

I'm glad some of the DOE money is going to Nano tech. I'd like to see more going to getting to develope large scale manufacturing processes as much as research.

Love this mouthful:

Price Is EV’s ‘Elephant in the Room’ | Autopia | Wired.com

What the automakers couldn’t do, Cogan notes, is develop a battery pack that costs less than $20,000 to $30,000. That’s still the case today, which is why the electric vehicles in the pipeline have price tags approaching $50,000.

The author covered the cost of batteries and touched on the price of electricity to fill those batteries but failed to mention the price of gasoline. Either todays price of $3ish or last year’s $4 price. Surely it will increase beyond that as it historically has always slowly crept up and passed previous records.
Cogan says,“There’s a shroud of denial that regularly excludes the real cost of battery electric vehicles from discussion of their considerable benefits,” ”
So what about the Federal spending that shrouds the real cost of the gasoline used to propel today’s cars? The $1Trillion price of wars in lands we want the oil from (even WW1 was a war for oil) the uncalculatble cost of 10s of thousands of American and foreign lives and then there are the subsities we keep giving to the oil companies even while they record breaking profit every quarter. Why do we have to keep giving them money? Because they threaten to raise gasoline prices on us as opposed to only making a reasonable profit?
Estimates say the true cost of gasoline in the US should be about $15 dollars a gallon and that certainly jives with European prices a $10 a gallon.
Batteries are at least recyclable. Gasoline burns up once and fills our lungs with stuff.
