Why do batteries need a pressure normal?
Applying a pressure normal to the active planes will keep the layers working together. Gas generation is a byproduct of electrochemical and chemical reactions inside the battery, which can occur when the battery is operational or in storage. The gas generation rate is dependent on chemistry, manufacturing quality, and battery management.
