That can bend and be drilled through while still working.

Click here to read the full story, but in a nutshell, the battery can be charged in about a minute, and uses aluminum anodes with graphite cathodes to create a working prototype. Obviously, capacity isn't mentioned this early in the game, but I imagine that that will be fairly easy to scale up.

The one major hurdle is voltage output. While it puts out about 2 volts after thousands of recharges (which is higher than most other aluminum-ion batteries), that's only about half of what a lithium-ion smartphone battery puts out. They do show in the video that pairing two batteries can power a smartphone, proving that that jump to smartphone level batteries could be closer than we all think.

Also, think of the large-scale applications. This innovation could be the tech necessary for Tesla Motors to make the jump into the rural/long-distance car market by making charge times shrink even smaller than what they are now. Paging Elon Musk...
