Interesting. Automobile batteries are not exactly the lightest things around.
It is probably cheaper to deal with nuclear waste than all the waste that is going to be created by all these ‘green’ batteries.
I want a light weight long lasting battery for my power tools not to mention my cell phone that needs to be charged every 3 day with little use...
Say did you this about government motors volt?

” . . . companies could also keep the battery weight the same but increase the amount of energy they store by as much as 50%, Cui suggests.”
Why would they want to do that? 40 miles on a charge is the most anyone would ever want in an electric car :)
