Customer ServiceThe humidity level in battery manufacturing varies depending on the stage of the process. Typically, during cell assembly, currently, the dew point ranges from -35°C to -45°C, corresponding to an absolute humidity of 0.10555 to 0.2841 grams of water per kg of dry air.
Because of the material sensitivity, solid-state battery dry rooms may need humidity controlling to minus 40.0°Cdp at the point of return. Furthermore, dry rooms for lithium batteries need a greater humidity control of around minus 50.0°Cdp at the point of return.
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.
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.
Water vapor acts as a catalyst, thus the rate at which these reactions occur depends upon both the moisture level in the atmosphere and the time that the lithium metal is exposed to that moisture. The more exposure, the poorer the quality, performance, and shelf life of the batteries.
The requirement for increased air dryness driven by the push for lower humidity levels in clean rooms has led to increased energy consumption, which constitutes a significant portion of lithium-ion battery production costs.
