Overview
IEC TS 62607-4-1:2015 - Nanomanufacturing – Key control characteristics – Part 4-1 provides a standardized electrochemical characterisation method for cathode nanomaterials used in nano-enabled electrical energy storage (for example, lithium‑ion batteries using lithium iron phosphate, LFP). This Technical Specification (2nd edition, 2015) defines sample preparation, a 2‑electrode cell test method, measurement procedures and data interpretation intended for materials-development and comparative studies (not final product qualification).
Key topics and requirements
- Scope and purpose
- Standard method to determine electrochemical properties of cathode nanomaterials to help users decide usability and select suitable materials.
- Applicable to materials whose performance improvement is enabled by nanotechnology (percentage content is not the determining factor).
- Sample preparation
- Guidance on reagents, cathode foils, anode selection, solvents, separators, pre‑treatment of nanomaterials and construction/disassembly of a screw cell for testing.
- Electrochemical measurements
- Standardized experimental procedures and conditions for:
- Open circuit voltage (OCV) measurement
- Potentiostatic Electrochemical Impedance Spectroscopy (EIS)
- Charge–discharge testing (constant current / constant voltage, CCCV)
- Data analysis
- Interpretation methods for OCV, EIS and CCCV results to compare electrochemical behaviour, impedance, capacity and cycling performance.
- Supporting material
- Informative case study demonstrating sample preparation and results for an LFP electrode.
- Normative reference
Applications and users
IEC TS 62607-4-1 is valuable for:
- Battery researchers and academic groups developing nanostructured cathode materials.
- R&D teams in battery and materials manufacturers evaluating candidate nano-enabled cathodes (e.g., LFP composites).
- Quality control and materials testing laboratories performing comparative electrochemical characterisation.
- Standardization experts and regulators seeking harmonized methods for reporting electrochemical performance in the development stage.
Practical uses include benchmarking new cathode nanomaterials, screening formulations before scale-up, and generating reproducible OCV, EIS and CCCV datasets for cross‑lab comparison.
