Abstract

A battery cell including an electrode assembly contained within a housing. The electrode assembly shrinks and/or swells depending on a charge/discharge cycle of the cell. A swelling compensation member configured to shrink upon swelling of the electrode assembly, and expand upon on shrinking of the electrode assembly is in continuous contact with the electrode assembly and an innermost surface of the housing. A first portion of the innermost surface of the housing is in contact with the swelling compensation member, and a second portion is free from contact with the swelling compensation member. The battery cell includes a cooling member in thermal contact with the outermost surface of the housing. Part of the outermost surface of the housing in contact with the cooling member corresponds to a part of the innermost surface of the housing which is free from contact with the swelling compensation member.
