Scope

This document describes a method for determining the moisture content of nano-electrode materials in nano-energy storage devices using the Karl Fischer coulometric titration method.
This document includes sample preparation, the experimental process for determining the characteristics of nano-electrode materials, and data analysis methods.
Note: The accuracy of this method is up to 0.0001%. The optimal measurement range is 0.01% to 1%.
This document is not suitable for samples that can react with the main components of Karl Fischer reagent to produce water, or samples that can react with elemental iodine or iodide ions.
