Webinar recording: Meeting New Requirements for High Voltage EV Charging Connectors

23 November 2023

Silver is the element in the periodic table with the highest electrical conductivity and therefore the prerequisite for connector contacts with the highest possible power transmission. However, both fine silver (pure silver) and hard silver coatings (silver alloys) do not yet meet all the technical properties required by the industry in terms of quality:

High electrical and thermal conductivity
Temperature-stable hardness until the end of the service life
Extended service life (longevity) of the contacts/connectors
Improved wear resistance and corrosion resistance
High number of mating cycles without loss of performance

The desire for significantly longer durability of silver coatings for such high-performance applications (e.g. high-current connectors in electromobility) is obvious - no wonder, as this is the basic prerequisite for longevity and thus improved cost-effectiveness.

Our expert Robert Ziebart (Umicore Sales Manager & Technical Services) will demonstrate the advantages of our silver-graphite dispersion electrolytes in detail. Following his presentation, he and Kevin Martin (Umicore Business Development Manager) will answer questions on the topic.
