This part of IEC 62607, which is a Technical Specification, specifies a test method for the determination of water content in electrode nanomaterials for nano-enabled electrical energy storage devices, using the Karl Fischer coulometric titration method.
This document includes:
- recommendations for sample preparation,
- outlines of the experimental procedures used to measure electrode nanomaterial properties, and
- methods of interpretation of results and discussion of data analysis.
NOTE This method has precision as low as 0,000 1 %. The best applicable measure range is 0,01 % to 1 %.
This document is not applicable for samples that can react with the main components of Karl Fischer reagent and produce water, or samples that can react with iodine or iodide ion.
