Here's a random link that has some good info. http://www.eaaev.org/eaaevsforsale.html
Also good old wikipedia http://en.wikipedia.org/wiki/Battery...icle#Batteries
If you haven't seen Who Killed the Electric Car http://www.ei2025.org/previous_editorial.asp?e=103
Hopefully those of you who find this interesting will google up some information yourself because I can't possibly post links to everything...
