Pigments and Extenders for E-Mobility – LUM GmbH contributes to standardization

In October, a workshop on Pigments and Extenders for E-Mobility took place at DIN e.V. in
Berlin.

The DIN Standards Committee Pigments and Extenders (NPF) has the task to carry out the
standardization in the field of pigments, dyestuffs (excluding dyestuffs for textiles) and
extenders and to assure the representation of national interests at international and
European levels. The NPF leads the secretariats of ISO/TC 256 "Pigments, dyestuffs and
extenders" and of CEN/TC 298 "Pigments and extenders", which are responsible for the
international respectively European standardization of pigments and extenders. [1]. LUM
has been actively involved in ISO/TC 256 for years.

E-mobility is a central aspect of the global shift towards sustainability, which highlights the
importance of climate protection, circular economy and environmental protection. As raw
materials and additives, pigments and fillers play a crucial role in the development of

emobility solutions and contribute to the creation of sustainable and environmentally
friendly transport options. In the field of e-mobility, the development of new pigments and
fillers and their standardization is a crucial element on a global level, even if implementation
varies in different countries, companies and industries. Academic symposia tend to focus
on specific methodologies, but capturing the broader and more diverse facets, particularly
with regard to standardization, is essential to re-establishing the fundamental principles of
this topic. This workshop aims to provide comprehensive information on various aspects of
e-mobility, including the role of standardization, working strategies and characterization.
He will address the global trends in e-mobility, as well as ideas for the future work of ISO/TC
256 "Pigments, dyestuffs and extenders" on standardization in this area, with general
standardization efforts in the EU/DIN on this topic and with company strategies. Organized
by the Association of the Mineral Paint Industry. V. (VdMi), which represents several German,
internationally active pigment and filler manufacturers, and the German Institute for
Standardization e. V. (DIN), the national standardization organization in Germany, which
runs the ISO/TC 256 secretariat, this workshop will also present characterization work that
makes a valuable contribution to e-mobility [2].

Prof. Dr. Dr. Dietmar Lerche, Managing Director of LUM GmbH, reported on the topic:
Analytical techniques to address optimization and quality assessment along the
development and processing of electrodes: A first step for standardization. The focus of his
remarks was the STEP-Technology® developed by LUM for characterizing particle properties

and particle interactions, as well as the CAT-Technology® for determining the mechanical
properties of electrode layers. While STEP-Technology in combination with optical
detection has been used in fuel cell technology since 2008, its expansion to include X-ray
technology in recent years has made a significant contribution to the simple and rapid
characterization of battery pastes in the original concentration, thus enabling product and
process control, which is not possible with optical analytical methods.
The final highlight of the contribution was the presentation of a first standardization draft
within the framework of the International Electrotechnical Commission (IEC), TC 113:
Nanomanufacturing - Key control characteristics - Carbon black materials for energy
storage devices quantification of Hansen parameters. Carbon black is an important material
for electromobility and the energy transition. Customization for other pigments and fillers
is possible. In this context, reference is also made to ISO 20427:2023 Pigments and extenders
— Dispersion procedure for sedimentation-based particle sizing of suspended pigment or
extender with liquid sedimentation methods.
