i found a metal rod inside a duracel battery, whats it made of?

after looking through (literally) some batteries that i had held onto in the hope that theyd contain carbon rods for elecrolysis.

i discoverd now what the signs are that a battery contains a carbon rod, and how to tell if its a wet cell.
now, i opened up a d size duracel wet cell, that contained a metal rod that looks identical to a blunt nail, and i was wondering, what is this made of? because , i kno theres a reason iron rodsa arent used inside these batterries, being because theyd rust, yet this has no rust at all, so im wondering wjhat is it? also, ide thought ide emntion it was attached to the negative terminal.

also, is the silvery metalic flaky dust stuff inside the paper roll inside said battery pure zinc? or is it zinc oxide, because ide very much like to try to use it to make zinc sulfide for glow in the dark plastic, so would it work?

As below for the rods in the alkaline batteries.
If you're looking for carbon rods, you need zinc-carbon batteries.  These are the old sort which have just about been superseded by alkalines and rechargeables etc.

i dont gdet it, that information is extremely inaccurate to what i have discoverd

in batteries i have found two types, ones with carbon rods, and ones without
the ones with carbon rod contain no moisture and whats more, no zinc chloride!!
the zinc chloride batteries which have a zinc paste in the middle do not contain a carbon rod attached to the positive terminal, all batteries i have opened up that have zinc paste do not have carbon rods, whats more, they are wet insi andleak ammonium chloride goo when opened.

thoigh there is something i want to ask, and please PLEASE ANSWER IT .
if i find an untarnished zinc-carbon battery, can i use its zinc case to make pure-ish zinc powder suitable for use to make zinc sulfide?
the reason i ask this is because i can no longer buy zinc powder from my old and only source.
There is also the old sort which has a carbon rod and a gungey black substance (manganese dioxide). The case of these is zinc which I think is pretty pure so you could make zinc sulphide from it.

I found a few links that they may help you :

  1. - Zinc sulfide glow power at home

  2. - Method of making zinc sulfide

  3. - How To Make Glow in the Dark Slime

- Also with that metal rod you can make a "water analyzer" device . For make it you need two carbon rod . It's a simple picture I made for this device :

how do these links help me at all, they just say how to make zinc sulfide?
i already know how its made, im asking if i can use the zinc in BATTERIES as the source of zinc ( after being washed and milled of course)

now, whats the point of the water analyser? all its doing is splitting the water via electrlysis, big deal.

Probably steel, as rusting is an electrochemical process it doesn't necessarily occur in alkaline batteries (until they're well-"flat").
