Disposing Lithium battery cr2032

A recent event involving a lithium ion battery has prompted The Alamo Heights Fire
Dept. to provide safety information regarding the use, storage and disposal of these
types of batteries. Although there have been no recall of these types of batteries found,
it is important to follow basic safety guidelines.

Do not recharge batteries.
Do not deform batteries.
Do not mix different type of batteries.
Do not solder directly onto batteries.
Do not let water penetrate into packaging boxes during their storage and
transportation.
Do not store the battery in places of the high temperature exceeding 35 degree.
C or under direct sunlight or in front of a stove. Please also avoid the places of
high humidity. Be sure not to expose the battery to condensation, water drop or
not to store it under frozen condition
Keep batteries in their original packaging until use to prevent accidental short
circuit and damage

How Does a CR2032 Battery
Work?
CR2032 batteries are no different
from other kinds of batteries in
terms of their function. Each
battery is a tiny self-contained
electrochemical cell with a positive
and negative end. The CR2032
battery uses a combination of
lithium and manganese dioxide to
power a chemical reaction that
converts chemical energy into the electrical energy that powers portable devices like
watches and remote controls.
Every battery has a chemical it uses for the positive end and another it uses for the
negative end. In the CR2032, the positive electrode is composed of manganese dioxide
while the negative electrode is made of lithium. The lithium anode is placed on top of
the manganese dioxide cathode, and a salt bridge separator is placed between them.
In this reaction, the lithium side oxidizes, and the manganese dioxide side reduces. As
this occurs, electricity flows through the devices that the CR2032 battery powers. More
lithium comes out of solution and builds up on the surface of the negative end while
more manganese dioxide goes into solution.

Rapid-discharge issues
Lithium batteries can provide extremely high currents and can discharge very rapidly when
short-circuited. Although this is useful in applications where high currents are required, a toorapid discharge of a lithium battery can result in overheating of the battery, rupture, and even
explosion. Lithium-thionyl chloride batteries are particularly susceptible to this type of discharge.
Consumer batteries usually incorporate over current or thermal protection or vents in order to
prevent explosion
Air travel
Because of the above risks, shipping and carriage of lithium batteries is restricted in
some situations, particularly transport of lithium batteries by air.
The United States Transportation Security Administration announced restrictions
effective January 1, 2008 on lithium batteries in checked and carry-on luggage. The
rules forbid lithium batteries not installed in a device from checked luggage and restrict
them in carry-on luggage by total lithium content.

Disposing Lithium battery cr2032
Since lithium battery cr2032 cannot be recharged, it has to be disposed of properly.
One good thing about cr2032 battery is that it does not contain any reactive acids or
dangerous metals. When the battery stops working, the lithium element will be changed
to a non reactive metal. It does not produce heat on its own and it has no risk attached.
However, there is still a need to be careful when disposing of the lithium battery cr3032
in large numbers. Many of the batteries still retain a little quantity of charge and so when
positioned close to each other or thrown out together at the same time, it is possible for
them to short circuit and explode, causing fire.
For proper disposal of large numbers of lithium batteries at the same time, they can be
disposed of by scattering them in different directions so that they will not touch one
another. To prevent explosion, batteries should not be disposed close to each other.
Users can contact manufacturers of lithium battery cr2032 or electrical stores to learn
how to properly dispose used batteries. They will be able to provide the needed advice
on how to do it in a safe way.
