IEC TS 62607-4 Updates for Nanomanufacturing

The IEC TS 62607-4 series on Key control characteristics for Nanomanufacturing has been updated.  There’s a new Edition 2.0 for IEC TS 62607-4-1 and a new Edition 1.0 for IEC TS 62607-4-3.  We’ll review these new two IEC releases one at a time.  The series addresses cathode nanomaterials so important in energy storage moving forward.  Uses include “Smart Grid” applications, transportation, and so on.  These materials support effective energy storage that are key for renewable energy usage.

IEC TS 62607-4-1, “Nanomanufacturing – Key control characteristics – Part 4-1: Cathode nanomaterials for nano-enabled electrical energy storage – Electrochemical characterisation, 2-electrode cell method,” was originally released last year.   After the technical specification was released, IEC TC 113 (the specification’s authoring committee) and IEC TC 21/SC 21A (the committee for secondary cells and batteries containing alkaline or other non-acid) had further discussions regarding the publication.

As a result of those meetings, the title of the document has been changed.  And the scope of the specification has also been modified.  It now clarifies that the publication deals with a method for determining electrochemical properties of cathode nanomaterials.  This might include lithium-ion batteries utilizing lithium iron phosphate for example.  And you’ll find that the definition of “cathode nanomaterial” has been updated to be more concise.  So the new Edition 2.0 for IEC TS 62607-4-1 is indeed a technical update, replacing and cancelling the previous Edition 1.0.

IEC TS 62607-4-3, “Nanomanufacturing – Key control characteristics – Part 4-3: Nano-enabled electrical energy storage – Contact and coating resistivity measurements for nanomaterials,” has just been issued.  This part of the IEC 62607 series provides you with standard methods to measure coating and contact resistivity of nano-enabled electrode materials.  It also allows you to evaluate the best combinations of composite material recipes and fabrication technologies for carbon containing these nano-enabled electrodes.  And using this method, you’ll be able to compare the results of different research groups.

This technical specification has been written for use during the study stage, not for evaluating end products.  Since this material can affect the performance of electrodes even in small quantities, the percentage of the amount of nanomaterial of the device in question doesn’t affect the applicability of this document.  So the fraction of nanomaterials in electrodes, electrode coatings, separators or electrolyte is not relevant for using this specification!  Amazing.

When might you use the IEC TS 62607-4-3?  The test method presented can help you decide if a coating composite material is suitable for your purposes.  And you’ll be able to select the best combinations of coating composite material including the fabrication technologies suitable for their application.
