Battery Cell Heating Layer With Exhaust Venting for Uniform Heating

The patent extracts the harmful gas trapped between the heating component and battery cell surface by providing exhaust structures (exhaust vents or exhaust channels) that allow the gas to escape. This extraction of the harmful element (gas) enables complete adhesion of the heating component to the battery cell surface, eliminating partial dry heating and achieving uniform heating across the entire surface.

The patent converts the harmful effect of gas entrapment into a beneficial exhaust flow pattern. By designing exhaust structures that guide gas escape, the gas that would otherwise cause dry heating is channeled through controlled paths (exhaust channels) or released through strategically positioned vents, transforming the harmful trapped gas into a controlled exhaust process that enables complete surface adhesion and efficient heat transfer.

The patent merges the exhaust function directly into the heating component structure by integrating exhaust vents or exhaust channels into the heating component body. This integration allows the heating component to simultaneously perform heating and gas discharge functions through a single unified structure, avoiding the need for separate exhaust systems and thereby reducing overall structural complexity while maintaining reliable adhesion.
