Overview
IEC TS 62607-4-9:2026, published by the International Electrotechnical Commission (IEC), provides a standardized method for assembling coin-cell electric double-layer capacitors (EDLCs) using carbon nanomaterials. This technical specification is crucial for the consistent characterization of the electrochemical properties of carbon nanomaterials used as electrode materials in EDLCs, ensuring reproducibility and accuracy in research, manufacturing, and quality control.
The standard specifies procedures for electrode slurry preparation, coating, rolling, cutting, weighing, and final coin-cell assembly. It targets carbon nanomaterials like nanoporous activated carbon, carbon aerogel, carbon nanotubes, carbon black, graphene, nano graphite sheets, and vapour-grown carbon fiber. Adopting this method enables organizations to evaluate and benchmark the performance of nano-enabled energy storage materials in a systematic manner.
