Here’s kind of an old news item.  Kind of strange it didn’t show up on any of the standard gadget blogs.  There has been talk of Sony’s new LiIon battery tech that boosts capacity by 30%.  It’s called Nexelion, and heres the press release.  Already known is that a Nexelion-based battery will be made for the PSP.

Interesting. I didn’t know that. Well, imagine nexelion technology batteries in our VAIOs…  :D
