INTRODUCTION
This Technical Specification specifies how to report the various characteristics of electrodes for
industrial use in electrotechnical products, and how to incorporate these into a bilateral detail
specification between vendor and user.
Electrochemical capacitors are widely used in the fields of electric vehicles, high speed trains,
aircraft, photovoltaic, wind power and electronics, due to their ultra-fast charge/discharge
capability, long cycle life, wide working temperature range, high security reliability and low
maintenance cost [1] . In the manufacture process of electrochemical capacitor, the electrode
is a bridge between raw material and device. Therefore, the performance of the electrode is
very critical in the whole electrochemical capacitor industry chain because the properties of
electrodes not only reflect the performance of upstream raw material but also determine the
performance of electrochemical capacitor [2][3][4][5][6][7][8][9].
For the purposes of development and commercialization of raw nanomaterials for electrodes
and the electrochemical capacitor and assembly produced therefrom, the product
characteristics and characterization methods need to be specified in a standardized way. This
blank detail specification will benefit different stakeholders as follows: for material suppliers, it
provides necessary feedback from the manufacturers to guide the design and production of raw
materials; for the end-product manufacturers, it provides a toolbox for evaluating product quality
so as to manage and improve process control, yield of products; for commercialization and
trade, it provides a guidance on referred test methods for electrode classification; in addition,
it will strengthen the links between material manufacture and down-stream user.
In this blank detail specification, the key chemical, physical, structural and electrochemical
characteristics that will significantly influence the performance of electrochemical capacitors
and their measurement methods are listed. These characteristics and characterization methods
are not limited only to nano-enabled electrodes but also can be reference for other electrodes
which are constructed by coating electrode materials on a current collector.

Blank detail specification
1 Scope
This part of IEC 62565, which is a Technical Specification, establishes a blank detail
specification that lists the relevant key control characteristics (KCC) including chemical,
physical, structural, and electrochemical characteristics of nano-enabled electrode for
electrochemical capacitors. Electrodes of both electric double layer capacitors and pseudo
capacitors with nano/ nanostructured materials such as nanoporous activated carbon, graphene,
carbon nanotube, carbon black, carbon aerogel, carbon nanomaterial coating collector, etc.,
are included. For other electrodes, this document can be used for reference.
In addition, this document enables the customer to specify requirements in a standardized
manner and to verify through standardized methods that the nano-enabled electrode of the
electrochemical capacitors meets the required properties.
Numeric values to be specified for the characteristics in this document are intentionally left
blank and are determined by agreement between customer and electrochemical capacitor
supplier. Properties and characteristics deemed by the customer or supplier as not relevant to
a specific application are classified as "not applicable" or "not specified".

4 General introduction regarding measurement methods
For reasons of practicality for industrial use in manufacturing of nano-enabled electrotechnical
products, this document recommends appropriate measurement methods for each material
parameter. The specification of some KCCs of nano-enabled electrodes of electrochemical
capacitors refer to measurement procedures for which
– no standards currently exist, or
– standards are under development but have not yet been published, or
– standards were developed for other use cases but can be adopted with modifications.
In other cases, industrial users of this document shall fall back to methods which are used in
the scientific community. As they are not established as documented measurement procedures,
users of this document shall agree bilaterally on it. For the KCCs in this document, Clause 6
provides a general overview.
To fulfil the requirements of quality assessment management strategies this requires careful
documentation of the measurement procedure. The document describing the method used shall
have an identification number and include the following topics:
a) Measurement principle:
– basic scientific background;
– measurement configuration if there are different experimental setups available which
perform from a physical point of view the same measurement;
– measurement mode if there are measurement modes possible with the experimental
setup which deliver different kinds of information.
b) Measurement system:
– measurement equipment / apparatus;
– materials;
– calibration standards;
– ambient conditions;
– sample preparation method.
c) Measurement procedure:
– calibration of measurement equipment;
– detailed protocol of the measurement procedure;
– measurement accuracy.
d) Data analysis / interpretation of results:
– description of the method to derive the key control characteristics out of the
measurement data including the used key formulas.
e) Results to be reported:
– description of the test sample including a sketch, drawing or photograph;
– identification of the test sample, e.g. batch or serial number;
– quantitative description of the accuracy of the measurement;

– 16 – IEC TS 62565-5-2:2022 © IEC 2022
– measured key control characteristics listed in tables, plotted in figures, maps created by
scanning methods.
As this document is intended to be updated regularly, there will be a standardized method for
each KCC in the future, including supplementing, revising and replacing the reference
standards. Nevertheless, for special applications supplier and customer may deviate from the
recommendations and agree on other than the recommended standards or define a specific
method for their application.
