8. A method for operating a battery cell module, comprising:
-
receiving gases that escape from battery cells in the battery cell module within a gas receiving chamber; producing an opening through which the gases can flow when a predetermined gas pressure in the gas receiving chamber is exceeded, the opening produced in a lip valve which is connected to an outlet orifice of the gas receiving chamber, and sealing the gas receiving chamber with the lip valve with respect to an environment when a subsequent shortfall of the predetermined gas pressure in the gas receiving chamber occurs.
