Why does the lithium battery produce oxygen after it burns

- Oct 22, 2019-

Not all lithium batteries produce oxygen after combustion

If the positive electrode material of the battery is lithium manganate material, the structure is affected by temperature under high temperature conditions.

The positive electrode may have oxygen generated by a side reaction that generates oxygen at a high temperature.

The reason is related to the chemical bond strength of the material structure.

In the case of a lithium iron phosphate battery, the chemical bond of the material structure is strong, and the structure is more stable and difficult.

Release oxygen, so you need to know the positive electrode material used in the lithium battery to know if it will produce oxygen after combustion.
