Lithium Cell Batteries (1 Viewer)

Im doing the comparisons between dry cell batteries and lithium batteries.
I have some stuff on dry cell batteries, but not what i want for lithium. Does anyone have some last minute information about the impacts on the environment and Society... And I guess on cost and practicality.
I would be extremely greatful for your help

To be honest, I would be sticking with Dry Cells and Button Batteries (silver oxide). The information is so much easier to remember and there is more information about them because they have been around longer.

If you decide to do it, feel free to use this (I think it is right ha ha).
