Overview
IEC TS 62565-5-2:2022 - Nanomanufacturing – Material specifications – Part 5-2: Nano-enabled electrodes of electrochemical capacitors – Blank detail specification provides a standardized blank detail specification for nano-enabled electrodes used in electrochemical capacitors. This Technical Specification lists the relevant key control characteristics (KCC) - chemical, physical, structural and electrochemical - for electrodes of both electric double-layer capacitors (EDLCs) and pseudocapacitors using nano/nanostructured materials (for example: nanoporous activated carbon, graphene, carbon nanotubes, carbon black, carbon aerogel, and nanomaterial coatings). It enables customers and suppliers to specify requirements consistently and to verify properties using referenced measurement methods.
Key topics and requirements
The document focuses on clear, auditable specification and testability of nano-enabled electrode materials. Major technical topics include:
- General procurement information and product description format for bilateral contracts.
- Chemical KCCs: moisture (Karl Fischer), ash content (incineration, TGA), magnetic impurities (ICP‑MS/OES/ASS), etc.
- Physical KCCs: thickness, surface and rolling density, resistivity, surface roughness.
- Structural KCCs: specific surface area, pore volume, morphological descriptors for nanoporous and nanostructured carbons.
- Electrochemical KCCs: specific capacitance (CCC, CCD), voltage maintenance, leakage current, DC resistance, cycling endurance and temperature endurance.
- Measurement methods: Annex A provides documented procedures or references for many tests (e.g., Karl Fischer titration, TGA, ICP methods, BET surface area, contact angle, capacitance and leakage test protocols).
The specification format includes tables for KCC reporting and an overview table of measurement methods to support reproducible verification.
Applications and users
This Technical Specification is valuable for:
- Manufacturers and material suppliers defining product datasheets for nano-enabled electrodes.
- OEMs and system integrators (EVs, high-speed transport, aerospace, grid storage, renewable-energy inverters) sourcing electrochemical capacitors.
- Procurement and quality teams seeking standardized acceptance criteria.
- Test laboratories and R&D groups developing or validating electrode materials and cell performance.
- Regulatory and conformity assessment bodies referencing standardized KCCs for material evaluation.
Use cases include supplier-customer contracts, incoming material inspection, product development comparisons, and qualification testing for capacitor manufacturing.
