MARPOSS HAS DESIGNED A NEW EQUIPMENT FOR IN SITU ELECTROCHEMICAL DILATOMETRY

THE EQUIPMENT IS VALIDATED BY THE RESEARCHERS OF THE LEME

NEW EQUIPMENT FOR IN SITU ELECTROCHEMICAL DILATOMETRY

Marposs is taking up the challenge to stay a strong reference for the automotive market in the e-mobility era and we are proud to announce that we have designed a new equipment for in situ electrochemical dilatometry.

The contactless measurement system, validated by the researchers of the LEME (Laboratory of Electrochemiestry of Materials for Energetics) of the Department of Chemistry G. Ciamician of the University of Bologna, permits to not influence the dilation of the sample during the tests. In addition, different forces can be applied in a selected range. Graphite is selected as model electrode and electrochemical tests in different electrolytes are carried out under different applied forces.

The results of the electrodilatometric tests on graphite in EC:DMC- and in PC-based electrolyte reveal not only lithium insertion/deinsertion process, but also the presence of simultaneous phenomena.

We demonstrate that with this new equipment it is possible, from thickness variation, to collect information on processes of different nature. Specifically, different applied forces emphasized gas evolution, which is a worth studying phenomenon for increasing battery safety.
