What happens if a lithium-ion battery off-gases?
Once a battery off-gasses, if no actions are taken to remove the failure mechanism, the battery will proceed to thermal runaway and burst into fire. Fortunately, if the lithium-ion battery off-gas event is detected, many batteries can be prevented from going into thermal runaway conditions. Advantages of Lithium-Ion Fire Risk Prevention Systems
What happens if a lithium ion battery is heated up?
The main safety concern when installing a lithium-ion battery system is that the battery will start to burn and the development of explosive and toxic gasses. When a battery is heated up, it can start an internal exothermic reaction called thermal runaway. The image above summarizes the causes and consequences of thermal runaway.
