New air battery proposed for electric cars

Nikola Tesla successfully used zinc air batteries in the late 1800s to power electric cars. That technology was far simpler and much safer. I wonder why nobody is pursuing zinc air technology?

The problem is not just one of range though. I mean, how long does it take to re-fuel with good old petroleum,10 minutes tops? To recharge electric vehicles takes hours. This is the biggest fundamental problem with electric vehicles. The 100 or so miles range they have now would be adequate, if re-fuelling and charging times were any where near comparable. Although 500 miles would allow many more people to consider electric vehicles viable.

From http://www.sbir.gov/sbirsearch/detail/120642 An even more promising technology looms..... High energy density battery will be developed by combining metallic sodium anode with an air cathode. The proposed sodium-air battery is expected to dominate the performance of lithium-air battery. This battery technology is based on sodium conducting solid-electrolyte developed at Ceramatec Inc. The sodium conducting solid-electrolyte has conductivity in the range of 10-2 S/cm at ambient temperature and is expected to be chemically stable when in contact with sodium metal. The proposed electrolyte c... [More]

@Blueandi, I just don't see that as an issue. if you charge your car every night, like a smartphone, then you wouldn't really ever run out, assuming the range is increased. Which to me, means range is the ONLY real issue.

Thanks For The Power Source Info ! Now Locating All Those Electric Motors That Would Have Been Used In The Chrysler Town & Country Postal Mini-Vans is the Question ? I Hear They Are Already Using 250 HP Motors in EV Buses in LA, Toronto & Long Island already !

That Company in Utah (Technology Holding, LLC) Has Been Working Many Years On Advanced Battery Technology, etc !

I think originally it wasn't made because it was common belief that the gas engine would be cheaper and easier to make. As time went on, the auto industry became stuck with the gas engine and then dependant of gas. Making it harder and harder to switch til it got to the point that oil companies and auto companies were in bed together. Now, the oil companies won't allow the auto makers to change for loss of their main sorce of profits. It's too bad that Tesla didn't go farther with his invention and create a company that manufatured his idea. Would have change the course of... [More]

Ok. So I need to drive 200 miles, my vehicle holds enough fuel to do, say 110 (not realistic I know;but just as an example), so after 90 miles give or take, I find a petrol station. 10 minutes later I can drive the remainder of my journey. 3 and a half hours roughly at motorway speeds, no problem. In an electric car, that has a range of 110 miles, to drive the same distance would take an extra 5 hours or so, because of the length of time it takes to recharge (imagine waiting at a service station for 5 hours or more just to re-fuel). As I said, a higher RANGE would certainly go some way to al... [More]

If you check out Tesla and cars on the net you might find the story with an iron pipe antenna for the power drive in Canada. Researcher William R. Lyne noted the K Capture of iron to be around 7KV and set out to see what happened. A flame developed which he says is Nitrogen burning. Did Tesla develop a steam turbine car or perhaps all electric in some way. Tesla did say he could burn Nitrogen with his pulsing electrostatic electricity. That statement was on fliers for his Long Island Tower. Burning air as fuel has never been done and perhaps the least of the many free energy devices Tesla ma... [More]

Yeah well, the process of photosynthesis is far from their grasps yet they will invent something in order to keep you in theirs while touting a green design. How lovely. Get back to me in my next life when others have actually accomplished that fact.
