I have a dead AA Coppertop battery. I think there are things one can do
with the rod in a battery, e.g. carbon arcs, although I don't know how.
I won't ask about experimenting with the chemicals in the battery since
I've already directed that question to sci.chem.
Take it apart first.
The times I've done it, it wasn't a particularly easy task, and I recall
breaking a number of the rods.
There must be easier ways of getting the rods if you really have a need
for them.

Besides, I'm pretty sure that you want to go with a "plain"
(carbon-zinc) battery, rather than an alkaline (which is what
Duracell/Coppertops are) if you want to find a proper carbon rod.
Taking them apart is easy - just apply hacksaw around one end or the
other of the can.
