[clug] IBM claims to have made a new battery design that is environment friendly

[Brenton Ross]

One of the important characteristics of rechargeable batteries is the
number of charge-discharge cycles vs loss of capacity.This wasn't
mentioned, so it is either something they have a problem with, or they
haven't had time to do the tests.
I wonder if this announcement was rushed out because of the recent Li-S 
battery announcement.
