Abstract
Various embodiments herein relate to the design of battery stacks, batteries and battery packs that are able to accommodate volumetric expansion in the battery materials. These designs may be especially useful in connection with batteries having negative electrodes made of lithium metal and/or positive electrodes made of an electrochemically active conversion material. These batteries may expand on the order of 10-40% during cycling. The battery designs disclosed herein include compressible regions that span a wide variety of different designs and implementations.
