I was sold on the possibility of purchasing an EV with the thought of 1000 miles per charge. I mean, woo hoo! But then I read down to the part about not being rechargable. Bummer.

Guess I will keep driving the 1968 Pontiac and the 1984 Oldsmobile.

Now if the cost of the replacement battery is on par with the equivalent 1000 miles of gasoline, and the battery is easily changed. Then I am still on board for the EV revolution. But at the curent costs and limitations, as good free market guy, I will pass.

Chuck, I had the same reaction as GTOlover.  It seems like there are so many different chemistries that have been tried, but none are ready for prime time. 

I would assume that one would have to replace the Al battery when it was depleted.  How will this work? 

This sounds like my neighbor who works for a Government Lab.  He said that there was a program to get the battery price way down and the range way up over five years.  Then, as he says, it's game over.  Well, how many Government programs have we had with a goal than was never met.  The one that comes to mind for me is nuclear fusion. Another is the cost of spacecraft launches.   I am sure that other readers could come up with more.  What I have heard you say, after talking to various scientists, is that we are something like 20 - 25 years away from having an alternative.  This does not sound like one.

I understand your skepticism, GTOLover. In the 26 years that I've been writing about electric cars and batteries, there have been many, many battery chemistries: sodium-sulfur; zinc-chloride; nickel-iron; nickel-metal hydride; lithium-ion; lithium-sulfur; lithium-air; aluminum-air, just to name a few. And some of the claims have been way over the top. This new battery is an extremely ambitious undertaking with targeted performance numbers that are virtually off the scales. That's why it should be viewed with caution. I think Lux analyst Kevin See made a logical statement: It's a long-range concept.

Fair enough Charles. I know we need the science to get to the manufacturing. But the over the top claims always seem to have a caveat.

Yes, naperlou, Argonne got $120 million from the DOE in November, 2012 with a "5-5-5" goal. Five times as much energy, five times cheaper in five years. If we assume the specific energy at the time was 150 Wh/kg and the cost was $400/kWh, that means 750 Wh/kg at $80/kWh by 2017. I'll let our readers assess the possibility of that.

I agree with you, GTOlover. It's a long hard road. And history shows us that cliams by battery makers have often been way over the top.

Does air quality matter?

Since this chemistry is dependant on ambient air - does extremely polluted environments affect its functionality - such as a crowded freeway with a lot of exhaust?

Hi Charles,

Thanks for the article.

One thing that tells me this is a long shot is the comment section so far.  The passionate fans of EVs have not charged in to laud this as the next step that will finally make it all work for everybody.

I may well have an EV someday, but today is not that day and tomorrow does not look promising either.

Take care folks.

It's a start, but . . . . .

The average consumer is not going to want to pay to replace his battery every 1000 miles - the service interval is too short and he has come to expect batteries used in this type of application to be rechargeable.

IMO it will not be a market success unless they come up with a way to economically and non-invasively recharge the pack without replacing it or removing it from the vehicle.

I noticed the same thing, Bunter. It's also worth noting that three battery experts contacted by Design News declined to comment.
