1s2p battery pack for fast charge application-layered structure with PCM pouches and compressible foam for swelling absorption

A rechargeable battery pack may include at least one rechargeable battery cell and at least one phase change material (PCM) pouch in contact with the at least one rechargeable battery cell within a housing. The battery pack may include electrical conductors electrically connected to the at least one rechargeable battery cell to enable electrical power to be conducted to and from the at least one rechargeable battery cell. A compressible element, such as a foam element, may be positioned between a PCM pouch and an inside wall of the housing, thereby absorbing swelling of the rechargeable battery cell(s) to reduce risk of damage to the battery cells and battery pack. The electrical conductors may be formed on a rigid-flex printed circuit board (PCB).
