Abstract
A battery pack includes a battery housing and electrochemical cells disposed in the battery housing in a stacked configuration. Elastic bladders are disposed between adjacent cells of a cell stack. The elastic bladders are configured to serve as a compression spring that provide a predetermined compression force to each cell while accommodating cell growth during use. The elastic bladders may include surface features such as strategically shaped and/or located protrusions or restrained regions that are configured to permit compliance and can be tuned to address the requirements of a specific application and permit application of varying stiffness characteristics across a surface of a cell.
