PD IEC TS 62607 discusses key control characteristics for nanomanufacturing. PD IEC TS 62607‑4‑8 outlines 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 that helps in comparing characteristics and provides reliable results.
PD IEC TS 62607‑4‑8 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 1: This method has precision as low as 0,0001%. The best applicable measure range is 0, 01 % to 1 %.
Note 2: PD IEC TS 62607‑4‑8 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.
PD IEC TS 62607‑4‑8 on the water content in electrode nanomaterials is useful for:
Water can affect the electrical performance, cycling performance, and safety performance of nano-enabled electrical energy storage devices. Karl Fischer’s titration method is a direct method that is suitable for testing water in the gas, liquid, and solid samples. The method is useful for low water content levels (< 1 %).
PD IEC TS 62607‑4‑8 provides the best practice guidance for coulometric Karl Fischer reagents, analytical balance, sample handling, sampling, procedure, maintenance, the water content of the sample, precision, and test report for the determination of water content in electrode nanomaterials by Karl Fischer method.
This helps in the proper assessment of samples and ensures the results provided, are reliable and are reproducible in any laboratory. PD IEC TS 62607‑4‑8 also helps in improving performance and safety characteristics for electrode nanomaterials.
