Abstract
An expansion panel for installation against a battery cell in a battery assembly is disclosed. The expansion panel comprises two plates, wherein at least one plate is arranged to face the battery cell, and a spring layer between the two plates. The expansion panel may be able to provide pressure to the battery cell, while at the same time helping with cell cooling. The expansion panel may also provide a flame barrier, which may offer thermal runaway protection.
