1. An electrochemical cell or battery pressure application device, comprising:
first and second external plates;
a first internal plate adjacent to the first external plate, and comprising a first external dimension and a first internal dimension defining a first aperture corresponding to an exterior dimension of an electrochemical cell or battery;
a second internal plate adjacent to the second external plate, and comprising a second external dimension and a second internal dimension defining a second aperture corresponding to the exterior dimension of the electrochemical cell or battery;
a first compliant layer adjacent to the first internal plate, the first compliant layer comprising a thicker center portion positioned within the first aperture of the first internal plate and a thinner peripheral portion aligning with a peripheral portion of the electrochemical cell or battery, wherein the thicker portion comprises dimensions less than the first internal dimension of the first internal plate and the thinner peripheral portion comprises dimensions more than the first internal dimension of the first internal plate, the thicker portion held within the first aperture of the first internal plate and the thinner peripheral portion adjacent the first internal plate outside of the first aperture; and
a plurality of fastener sets for applying an adjustable pressure to the electrochemical cell or battery positioned between the first and second internal plates.
