Abstract: This disclosure relates to rechargeable battery packs and or rechargeable battery modules consisting of electrochemical cells in general and more specifically to lithium metal anode secondary electrochemical cells and the supporting mechanical structure of such packs or modules which apply and maintain a high and uniform normal compression pressure to the face of the interconnected cells of said battery packs, modules or individual cells, in order to suppress dendrite formation during charge and maintain a low cell impedance during charge and discharge. This is achieved with the use of a compression assembly having a compressible sheet with desired properties.
