Monitor the Moisture Content Across Your Battery Production 

Maintaining minimal water content is a strict requirement when producing certain types of batteries, like lithium-ion batteries. The Karl Fischer method is commonly used for routine monitoring of raw materials and environmental conditions, but it requires separate laboratory analysis. Sartorius thermogravimetric moisture analyzers allow for rapid evaluation of moisture content at various stages of production:

  • Quality control of raw materials - plastics, separators, graphite, active materials
  • Residual quantity of solvents after drying steps
  • In-process checking of electrode slurry or gap fillers
  • Characterization of materials after recycling or innovation stages

Quality Control of Incoming Goods

Small changes in the composition of a raw material can negatively impact the quality of the final product. Controlling, analyzing, and collecting data from each batch or supplier ensures the success of downstream steps. Sartorius MA 160 Moisture Analyzer allows precise measurement of moisture content in plastics (separators, casing, modules, packs), active materials, glue and gap fillers.

In-Process Determination of Residual Solvent Content

Electrodes for batteries are commonly made by a wet paint style application of the slurry onto either aluminum or copper foils. Drying steps influence the electrode thickness, substrate adhesion, and can lead to cracks. In lithium-ion batteries, water reduces the structural stability and capacity of the battery. Sartorius MA 160 Moisture Analyzer can determine the moisture content of liquids, pastes and solids conveniently, reliably and quickly.
