arstechnica.com — A new version of lithium battery technology can either provide a higher storage density than current batteries, or can charge and discharge as fast as a supercapacitor, emptying its entire charge in under 10 seconds.

LiFePO... did anyone else think life poo is funny? Cause thats all I'm going to think about when it comes to lithium from here on out.

It's one thing for power users to post their own stories, its another to steal other's finds.

That would be one helluva peak demand charge.

I can empty my entire charge in under 10 seconds also.

Buried because of power user.

Its a cheap alternative to a motorbike dumb ass... i suppose that means people who drive are super lazy.. hell lets get pedal cars!

This could REALLY boost the introduction of electric cars.

Blowing your mind department: newly published researchconcerning a "magnetic tunnel junction" device that could lead to a "spin" battery that transfers magnetic field power directly into stored energy without bothering with chemical reactions.The storage density is beyond my silly comprehension.Original publication:<a class="user" href="<a class="user" href="http://www.nature.com/nature/index.html&quot;" rel="nofollow">http://www.nature.com/nature/index.html&quot;</a> rel="nofollow"><a class="user" href="http://www.nature.com/nature/index.html&lt;/a&gt;" rel="nofollow">http://www.nature.com/nature/index.html&lt;/a&gt;</a>under "Advance Online Publication."<a class="user" href="<a class="user" href="http://www.physorg.com/news156011642.html&quot;" rel="nofollow">http://www.physorg.com/news156011642.html&quot;</a> rel="nofollow"><a class="user" href="http://www.physorg.com/news156011642.html&lt;/a&gt;" rel="nofollow">http://www.physorg.com/news156011642.html&lt;/a&gt ...</a>The device created by University of Miami Physicist Stewart E. Barnes, of the College of Arts and Sciences and his collaborators can store energy in magnets rather than through chemical reactions. Like a winding up toy car, the spin battery is "wound up" by applying a large magnetic field -- no chemistry involved. The device is potentially better than anything found so far, said Barnes."We had anticipated the effect, but the device produced a voltage over a hundred times too big and for tens of minutes, rather than for milliseconds as we had expected," Barnes said. "That this was counterintuitive is what lead to our theoretical understanding of what was really going on."<a class="user" href="http://www.physorg.com/news156011642.html" rel="nofollow">http://www.physorg.com/news156011642.html</a>&quot;The new discovery advances our understanding of the way magnets work and its immediate application is to use the MTJs as electronic elements which work in different ways to conventional transistors. Although the actual device has a diameter about that of a human hair and cannot even light up an LED (light-emitting diode--a light source used as electronic component), the energy that might be stored in this way could potentially run a car for miles. The possibilities are endless, Barnes said."
