Presentation Title:

The Control and Accurate Detection of Moisture Content in Lithium Battery

Presentation Abstract:

The moisture within lithium battery has the significant influence on capacity life span safety and other capabilities. Therefore, the researchers and manufacturers hope to keep the moisture content as low as possible in the R&D process and production. The smaller the particle is, the stronger the adsorption capability is. As a result, the dehydrated efficiency of pole piece would directly affect the moisture content of the lithium battery. The dehydrated pole piece would adsorb the moisture from the surrounding atmosphere that contains moisture once the pole piece exposes to it, so it is the other channel where the moisture in lithium battery comes from. Vigor has developed the relevant technologies for lithium battery industry. This report is to introduce the technologies and equipment about the accurate detection of moisture content, dehydration of pole piece, the control of moisture in atmosphere etc.
