Lithium-ion battery dry rooms for optimal product quality
In order to maximise product quality, critical production points are provided with microclimates where the room humidity must be as close to 0 as possible. If slight deviations in the humidity levels occur during the production process, this not only negatively affects the life cycle of the lithium cells, but also their maximum storage capacity over time. In order to be able to produce optimally, cleanliness classifications ISO7/ISO6 in accordance with ISO14644 must be achieved. The area of LIB rooms can range from small R&D lab environments to large scale mass production facilities. As already mentioned, lithium-ion batteries are very sensitive to humidity (Li + H2O > LiOH + H2). When lithium gets in contact with water, lithium hydroxide is formed, which is a highly flammable hydrogen.
