IEC TS 62607-4-6:2018

Overview

IEC TS 62607-4-6:2018 is a Technical Specification from the IEC 62607 series that defines a standardized method to determine carbon content in nano-enabled electrode materials using an infrared (IR) absorption spectroscopy method. The procedure applies to mass fractions of carbon from 0.001 % to 100 %, and is intended to support consistent measurement, data interpretation and inter-laboratory comparison for materials used in nano-enabled electrical energy storage (e.g., battery and supercapacitor electrodes).

Key topics and technical requirements

• Measurement principle: Infrared absorption spectroscopy for carbon quantification (high-frequency IR carbon/sulfur analyzer referenced).
• Applicability range: Carbon mass fraction between 0.001 % and 100 %.
• Sample preparation: Recommendations include controlled drying and tableting of nano powders to reduce measurement artifacts and prevent loss of material during thermal treatment.
• Apparatus and materials: Typical equipment includes an analytical balance, powder compressor, high-frequency IR carbon/sulfur analyzer, muffle furnace and crucibles; use of certified reference materials and specified analysis/carrier gases is described.
• Test workflow: Procedures cover start-up, blank verification, calibration/checking, analysis, reporting of results and data verification to ensure traceability and repeatability.
• Data analysis and interpretation: Guidance on result interpretation, consistency checks and discussion of measurement uncertainty; case studies illustrate typical workflows and inter-laboratory comparison results.
• Risk considerations: Addresses particular challenges with nano powders (e.g., material loss or contamination in furnace gas flows) and provides mitigation measures.

Practical applications

• Material selection: Helps R&D and formulation teams decide whether a nano electrode material is usable and select materials with appropriate carbon content for conductivity and performance targets.
• Quality control: Enables QA/QC for nanomaterial suppliers and battery manufacturers to verify carbon loading in electrode powders and composites.
• Research and development: Provides a repeatable method for academic and industrial labs comparing cathode nanomaterial recipes and studying carbon’s impact on electrochemical performance.
• Inter-laboratory comparability: Standardized procedures and case studies facilitate consistent comparisons across laboratories and studies.
