Lithium Battery Production

Controlled conditions for hypersensitive processes

In the manufacture of lithium-ion cells, the alkaline materials used for cathodes, anodes and electrolytes are exceptionally sensitive to moisture. This means manufacturers need to keep the air in their dry rooms at dew points far lower than in the ambient air. Target levels of -60°C and relative humidity of 0.5% is common.

The Cotes range of flexible dehumidifiers are specially designed and configured to make this possible, with the remarkable levels of reliability essential in lithium-ion battery manufacture and assembly.
