Might even power a Galaxy Note II for more than 15 minutes.

"Developing rechargeable lithium-ion batteries with high energy density and long cycle life is of critical importance to address the ever-increasing energy storage needs for portable electronics, electric vehicles and other technologies,"

The higher the energy density the more like an explosive these batteries become.

It is only a matter of time till some one figures out how to make a bomb out of a cell phone or a laptop computer that is indistinguishable from a normal one.

I am not saying these batteries should not be developed I merely state that it is inevitable.

I think I see that it improves the battery life; I don’t think I see that it improves capacity or energy density.
