New insight into electrochemical performance of organic cathode materials in Nature Communications published by the Researchers from the National Institute of Chemistry
(Ljubljana, February 15 2018) Today, the research team at the
National Institute of Chemistry presented its latest scientific achievement,
Development of new insight into
electrochemical performance of organic cathode materials was financially
supported by the ARRS and Honda R&D Europe.
To summarize the achievement, please continue reading news article, published

Organic cathode materials can be used in various battery systems like
lithium, sodium, magnesium batteries and can be prepared from low-cost and
sustainable resources, which makes them one of the promising materials for
future batteries. One of the pressing issues of contemporary research on the
cathode materials was the lack of characterization techniques that would allow
real-time monitoring of changes inside cathodes during electrochemical cycling.
With the financing from the Honda R&D Europe and Slovenian Research agency and
joint effort from two departments we developed a new method of probing changes
inside the cathodes through IR spectroscopy.
Method was developed for explanation of poly (anthraquinonyl) sulfide
polymer in Li and Mg batteries. In both systems we observed reduction of
carbonyl bond during discharge of the battery. The results of IR
measurements were confirmed through calculation of theoretical spectra and
synthesis of model compounds. New method presents a powerful tool for
research of new organic cathode materials and study of degradation processes
inside cathodes. Confirmation of the discharge mechanism in Mg battery
system opens new possibilities in research of Mg–organic batteries, where we
are successfully cooperating with Honda R&D Europe in the last five years.
