IEC TS 62607-4-8:2020 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. IEC TS 62607-4-8:2020 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.

Abstract

Overview

IEC TS 62607-4-8:2020 provides a standardized test method for determining the water content in electrode nanomaterials used in nano-enabled electrical energy storage devices. The document specifies the Karl Fischer coulometric titration method, a direct and highly accurate analytical technique capable of detecting trace amounts of water (as low as 0.0001%) in solid samples, specifically nanomaterials used in high-performance batteries and capacitors. This standard is published by the International Electrotechnical Commission (IEC) and is intended to support quality control for manufacturers and laboratories working with advanced electrical energy storage materials.

Key Topics

Scope and Purpose: This technical specification outlines procedures to accurately measure the water content in electrode nanomaterials-such as lithium cobalt oxide (LCO), lithium nickel cobalt aluminium oxide (NCA), lithium nickel cobalt manganese oxide (NCM), and lithium iron phosphate (LFP)-using the Karl Fischer method.
Sample Handling and Preparation:
- Recommendations for safeguarding samples from moisture uptake during storage and transport.
- Specific instructions for sample container selection and the need for controlled test environments (dew-point below −20°C).
Experimental Procedures:
- Detailed steps for maintenance and calibration of Karl Fischer coulometric titration apparatus.
- Measurement protocols including blank controls, replicate measurements, and data recording.
Data Analysis and Interpretation:
- Methods to calculate water content as a percentage mass fraction.
- Statistical treatment of results including repeatability (relative standard deviation
