Patent number: 9634295Abstract: A pouch battery cell container, including at least, one battery cell compartment, is interposed between two end plates. The planar electrode surfaces of a pouch battery cell, housed within the battery cell compartment, are subjected to a constant and optimal amount of compressive force during cell expansion and contraction for battery cell optimization. A first end plate and a second end plate are coupled together by a plurality of connecting devices, wherein each connecting device includes an elastic deformation component. As the battery cells housed within the battery container expand and/or contract, the first and second end plates move relative to each other while constrained by the elastic deformation device so as to maintain a constant amount of compressive force on the planar electrode surfaces housed within the battery cell.Type: GrantFiled: January 15, 2010Date of Patent: April 25, 2017Assignee: Pellion Technologies, Inc.Inventor: William P.
