doubt chemistry CR2032 battery

[ranger87]

What is the chemical composition of the CR2032 battery?

Is it an oxidative corrosive chemical composition for metals and PCBs?

over the years and storage battery this chemical composition of CR2032 changes and turns into a corrosive oxidative chemical compound that leaks and corrodes?

Wow!

Two new aliases and two new countries just today - it is hard to keep up....

Have you read this thesis: https://www.gutenberg.org/files/14986/14986-h/14986-h.htm 
All batteries produce electrical current by oxidation/reduction reactions, aka "REDOX" reactions.  The CR2032 is no exception (https://en.wikipedia.org/wiki/Lithium_metal_battery ).

The anode is therefore that surface at which the electric current, according to our present expression, enters: it is the negative extremity of the decomposing body; is where oxygen, chlorine, acids, &c., are evolved; and is against or opposite the positive electrode. The cathode is that surface at which the current leaves the decomposing body, and is its positive extremity; the combustible bodies, metals, alkalies, and bases, are evolved there, and it is in contact with the negative electrode.

Whether a battery leaks is mostly a matter of how it is constructed, albeit some chemistries seem to be more prone to leakage and causing damage than others.

Nice work

I have no idea how you gather that info, some automated method...or must be quite some time?

My guess he is a member of all those boards, or just used a search to find those common questions, using an exact text match mask.

List built up over the years since 2017, plus a little Googling

What I hate most are the blatant lies that insult the intelligence of all of us

I worry that this obsessive behaviour of mine is more obsessive than gamer87

... or maybe it is an over-blown sense of justice or fairness?

I guess gamer87 and I both need therapy 

EDIT - just found a CR2032 question from 1 May 2016

Some people say that cr2032 leaks others say that cr2032 does not leak and I am in doubt if I can keep them on the PCB or remove them all because of leakage and corrosion of the pcb

if you have/keep more details pls update the https://www.stopforumspam.com/
it's a valuable tool, I m admin on a forum and this database is quite handy.

Specifically, the CR2032 battery is a Lithium-manganese dioxide battery (LiMn02). It is composed of a Mn02 cathode and a lithium anode. The construction of a typical CR2032 battery features a stainless steel case to prevent any leakage of the non-corrosive electrolyte.
