Why measuring moisture is vital in Li-Ion battery manufacture

Lithium offers considerable advantages over other battery technologies and, as a result, lithium batteries are now widely used in mobile phones, laptops, and electric vehicles.

Moisture Measurement Critical in Lithium Ion Battery Manufacture?

Michell Instruments continues..

Moisture measurement is a crucial element of lithium battery manufacture because lithium can become explosive if it comes into contact with water. Indeed, even the presence of a very low concentration of moisture during lithium battery manufacture can cause corrosion on metal surfaces. 

 Chilled mirror analyzers and transmitters using either thick-film or ceramic metal-oxide sensors are two of the most effective technologies for measuring ultra-low levels of humidity.  

Lithium is a fascinating alkali metal.  It is found widely in the earth’s crust, where it normally occurs at low levels of dispersion in pegmatitic (coarse crystalline igneous materials) minerals, granite and in clay deposits and aqueous sources.  This can make it difficult to mine or extract.  Yet, once this soft silver-colored metal has been processed and converted to different compounds, it offers a range of unique properties.  As lithium stearate, it is used as a thickener in industrial greases; as lithium oxide, it is used in the manufacture of pottery glazes; and, in the form of lithium salts, it is used as an additive in anti-depressant medicines.
