Lithium-ion cells in hybrid and electric vehicles may pose a high risk if they have been thermally stimulated so that a chain reaction is no longer mandatory. The air volume then escaping impacts the housing of a battery so much that it is possible to refer to it as an uncontrolled deformation. There are solutions to mitigate this case. Through the use of bursting diaphragms/rupture disks or pressure compensation elements, the housing is relieved so that temperature differences are compensated and unavoidable fires are delayed in time. Hugo Benzing explains the correlations. ...
