Abstract
A battery module is provided. The battery module includes a plurality of battery cell assemblies configured to electrically communicate with each other. Each battery cell assembly has an electrode stack enclosed by a case. The electrode stack is positioned in the case to form one or more peripheral spaces between the electrode stack and the case. Support members are positioned adjacent to each of the battery cell assemblies to contact a desired portion of the electrode stack. The support members are configured to focus a compressive force on a desired portion of the electrode stack. The compressive force urges gases formed during operation of the electrode stack into the peripheral spaces within the case.
