Howdy all,

Saw the following headline on Yahoo

"Breakthrough Could Mean 40-Hour Laptop Batteries"
http://tech.yahoo.com/news/nf/57832

Could somebody with a better understanding of Li batteries explain how this might affect not only laptop batteries but other batteries that are near and dear to our hearts. I was also interested if anyone knew how the Li batteries scale to larger size. Battery size being a major stumbling block for Electric cars(ful size), could this advancement be applied in that direction sucessfully?

Food for thought.
