Yes, naperlou, a lot of chemistries have been tried over the past 40+ years, with "mixed" results. Battery chemistries often look good before the automakers start testing.

The aluminum-oxygen bond is so tight that the metal  was "precious"  until electrolytic refining came along shortly before 1900 .It's energy intensive which is why  aluminum refineries are  concentrated near hydroelectric power as in our Pacific Northwest(Bonneville dam) and Tennessee Valley  (Alcoa, Tn). That so much energy  has to be put in to separate the atoms  suggests  considerable should be  available by letting them recombine. 

I'm not enough of  a chemist to make such a battery

but intuitively  aluminum-aluminum oxide would be better chemistry for a lightweight  vehicle than lead-lead sulfate.

When they package the battery pack as a plug-in that you swap out in a couple minutes at the 'filling station'  is when the EV  becomes practical,  IMHO. 

I daydream about  tossing  a few  crushed soda-cans into something that resembles Doc Brown's  "Mr Fusion" on the Delorean.

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

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.

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.

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?

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.

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.

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.

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.
