Actually, there have been some very promising breakthroughs in battery technology, especially over the last 10-20 years. The problem is that most of these breakthroughs never seem to see the light of day, outside of the lab, in actual products.

I collect articles (download them as I read them - yeah, I know, I know, it's the OCC in me). I'm on my trusty, old Dell laptop at the moment, so only have a few old "battery" related articles here with me, but these seemed like they could be some promising breakthroughs of recent years (sorry, but they are all Geek.com .... hope the links still work):
