Furthermore, dry rooms for lithium batteries need a greater humidity control of around minus 50.0°Cdp at the point of return. The battery chemistry of the next generation of lithium batteries may have even tighter requirements. The specification could reach minus 80.0°Cdp at the point of supply into critical areas, such as Electrolyte Fill.
These classes belong to the middle class of cleanliness. But besides the cleanness, the process room in battery manufacturing shall be dry. A dry room is a premises with a controlled low moisture level in the air.
Humidity control is critical in battery dry rooms as various materials and processes used in battery production are susceptible to moisture damage. A low dewpoint air supply will mitigate the risks by creating a stable production environment suitable for the materials and processes. But what is a dry room? And how can the low dewpoint be sustained?
