Abstract
A spring compression assembly is configured to apply a load to a stack of electrochemical cells. The assembly includes a ceramic leaf spring, a tensioner configured to apply pressure to a first side of the spring and a bottom plate located on a second side of the spring opposite the first side of the spring. The bottom plate is configured to transfer a load from the spring to the stack of electrochemical cells.
