What is thermal runaway?

Thermal runaway is the chemical process within the battery that produces heat and chemical gases very quickly before any flame appears.

These gases are not something you would want to be exposed to.  They are vented from the cells as a vapour cloud.


Carbon monoxide
Carbon dioxide
Hydrogen fluoride
Hydrogen chloride
Sulphur dioxide
Hydrocarbons such as ethane, methane, butane, hydrogen cyanide
