Metals, ceramics, composites, and polymers all benefit from the use of isostatic pressing to densify and remove porosities and voids in cells. Isostatic pressing has been shown to increase contact between interfaces of components in solid-state battery cells leading to enhanced conductivity, higher energy density (Wh/l) and reduced volume change during operation. Isostatic pressing is also used in the production of individual components that are necessary to drive the development of future battery technologies.
