Battery presses

Most commonly the warm isostatic processing step is located after pouching and sealing of the cell, enabling the press to be located outside of dry room conditions.

Although the battery industry is focused on pressing complete multilayer cells, it is also possible to press electrodes and solid electrolytes by themselves before stacking.

Given the horizontal press design enabling one-directional material flow, the available range of large vessel volumes and existing automation solutions of our integration partners, the throughput of a high-volume production line will not be bottlenecked by the Warm Isostatic Pressing (WIP) process if sized correctly.

While we are open to different approaches and chemistries, the current focus is on sulfide solid electrolyte cells and the pouch cell format as these appear to have highest industrialization momentum.

Concepts such as “anode-free” designs, lithium metal anodes and dry-coated electrodes are very interesting for us on a production level of testing.

The cost of warm isostatic cell processing in GWh scale production is projected to be in the lower EUR cent area per kWh.
