Venting
Gases can build up in a cell over time or suddenly when the cell fails. At some point, and depending on the cell design, the gas pressure will cause the safety valve in the cell to release or the cell case to fail. A cell venting doesn''t necessarily mean it will go into thermal runaway, but a thermal runaway will be predated by the cell venting.
