Hello Youtubers, welcome to my fifth video
on Youtube and today I would like to show
you, where to find free Carbon electrodes,
Zinc and Manganese dioxide.
All those interesting things can be found
in zinc-carbon battery, commonly known as
a �cheap battery�.
Before the main autopsy of the battery, we
should tell something about its anatomy. The
metal case is Zinc, underneath lies layer
of manganese dioxide and in the center of
the battery is carbon electrode.
These are all the main parts we want.
As I promised in the beginnings I will try
to get all these part for free. That means
I will use found discharged batteries. Recovery
of zinc and manganese dioxide will be lower,
but at the end I will introduce an idea, that
might improve it.
Dry cells as cheap as they are come with one
major disadvantage, they discharge even when
they aren�t used. So these batteries bought
a year ago are absolutely useless, although
for purposes of our experiment they are just
fine.
OK the autopsy can now begin.
At first it absolutely necessary to remove
plastic casing.
Then continue with removing metal top, It
can somehow resemble to opening a tin.
Beneath this useless metal case is the carbon
electrode. Remove it is quite simple, It only
takes to use pliers. Before It can be used,
it must be cleaned.
Best way to remove zinc case is to peal it
like an orange.
The layer beneath zinc case is to be removed
and thrown away.
The actual mixture of manganese and zinc compounds
needs to be cleaned, if we intend to use it
in the future.
This is an amount of manganese compounds,
carbon electrodes and oxidized zinc metal
that can be scraped from 5 discharged batteries.
The last idea, maybe for the next video. Let�s
say we want manganese dioxide, that is depleted
during discharging, theoretically I can be
regenerated by heating the mixture to 300�C.
I think It�s all for the moment. Thank you
very much for watching, just remember I have
also other videos. If you like the video give
like, comment, subscribe. So thanks again
and see you later.
