Isostatic Pressing is a proven technology for consolidation of powder and densification of solid materials

Metals, ceramics, composites and plastics all benefit from the use of isostatic pressing to densify and remove porosities and voids.

With typical pressures from 800 to 6,000 bar (11,603 to 87,022 psi) and temperatures up to 2,000°C (3,632°F), isostatic pressing has been shown to increase contact between components in solid-state battery cells leading to reduced resistivity and higher power density. Isostatic pressing is also used in the production of individual components that are necessary to drive the development of future battery technologies.

Common application areas include ceramics, carbon-based materials and electrolytes compaction.

Scalable processing of solid-state battery (SSB) components and their integration is a key bottleneck toward the practical deployment of these systems. This paper highlights isostatic pressing (ISP) as a versatile processing platform for large-scale production of the currently most promising solid electrolyte materials.

Solid-state battery technologies have been under development for many years with the inherent possibilities to improve safety, reduce charging times and improve energy density. The paper explains how this solution is replacing Li-lon batteries due to the advent of electrification of the automotive and aerospace sectors.
