Tesla patents hint at 400 mile hybrid Lithium-ion/Metal-air battery

http://cleantechnica.com/2013/09/19/new-tesla-patent-400-mile-battery-pa...

"A report by Global Equities Research shows that Tesla recently filed patents 20130187591 and 20130181511, which describe a combination lithium-ion and metal-air battery pack."

The first Tesla patent application describing and claiming this was actually filed in the US Patnet Office in August 2010. So not really recent, very interesting indeed.

Exciting news! I've read about the metal-air battery packs but figured they were at least five years away, if not more, from practicality.

Boring. Metal-air oxidizes the metal. Un-oxidizing it is ssllloowwww and difficult, requiring extraction and replacement of the "battery". Not happening.

Check out this new nano-battery technology:

Power on demand. Already for sale. Why not in a Tesla?

I can't find any mention about power or energy densities of their tech in that page. If you have found mention could you post a direct link to that.

My guess it sucks as automotive battery, and that is why not in Tesla.

Timo;
In their Nanobattery Science section: "High Power and Energy Density".
Didn't scour the site for numbers, though.

Timo | 24 settembre 2013

Apparently they don't have any numbers to give. Long shelf life seems to be only real advantage for now. It also looks like those batteries are not rechargeable.

Yes, Oxygen would oxidize the metal in the Anode... if it ever contacted it. The key is to make sure the non-corrosive electrolyte completely covers the anode, effectively preventing any oxidation.

Timo | 27 settembre 2013

Metal-air requires oxidation. That's how it works.
