6 FAQs about [Lithium-ion battery production and assembly moisture]
How does water vapor affect lithium batteries?
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.
How are lithium batteries made?
The most important single factor governing the manufacture of lithium batteries is the fact that they must be produced in a very low humidity environment. In the early years, moisture free (inert gas) glove boxes were used to produce the batteries in small quantities.
Does water affect lithium ion batteries?
With the ongoing development of producing high-quality lithium-ion batteries (LIB), the influence of moisture on the individual components and ultimately the entire cell is an important aspect. It is well known that water can lead to significant aging effects on the components and the cell itself.
What is the moisture behavior of a LIB cell?
Since avoiding water within the LIB components and the cell is inevitable, the moisture behavior of all components needs to be fully understood. Depending on the relative humidity around the material and characteristics of the material itself, sorption equilibria of moisture within each component are established.
Are competencies transferable from the production of lithium-ion battery cells?
In addition, the transferability of competencies from the production of lithium-ion battery cells is discussed. The publication “Battery Module and Pack Assembly Process” provides a comprehensive process overview for the production of battery modules and packs. The effects of different design variants on production are also explained.
Does moisture affect Lib?
The fact that moisture can have an impact directly on components of the LIB or the entire cell is widely known and scope of research for many years. Small amounts of water are inevitable to occur during the production of LIB, due to the hygroscopic behaviors of the LiPF 6 within the electrolyte , and electrode materials , .
