“Developments in the use of isostatic pressing for production of solid-state batteries”

Next generation solid-state batteries (SSB) offer increased power and energy density compared to conventional Li-ion batteries (LIBs) with enhanced safety. SSBs use a dense, bi-functional solid material that acts as both the electrolyte and the separator. Although several materials have been identified for application as solid-state electrolyte, suitable production routes need to be developed for realization of all solid-state batteries. Realization of excellent mechanical contacts and zero porosity give rise to the need for densification of battery components and cells [1].

Global industry actors are now investigating the use of extreme pressure to ensure densification of battery components and cells. Isostatic pressing involves the use of a pressure medium to compact components under immense isostatic pressure, a technology that is well known in other industries since the 1960s. While hot isostatic pressing uses a gas pressure medium [2], Cold and Warm Isostatic presses (CIP, WIP) use liquid media. As the name suggests, CIP operates at room temperature, however WIP can operate at higher temperatures which aids densification. This technology is of great interest to densify batteries, to reduce resistivity and improve battery properties [3].

Quintus Technologies is the leading producer of isostatic pressing equipment and are engaged in the development and production of HIP, CIP and WIP equipment for future battery systems. This presentation will focus on WIP equipment developed for battery research and scalable production using wire-wound pressure vessels and state of the art technology for temperature uniformity, which has been based on input from major global battery producers and research institutes.
