Zn-air battery testing with the polymer-derived catalysts from University of Tartu
Zn-air batteries (ZAB) and fuel cells (FC) are green solutions for the growing need for energy conversion technologies. Although, an alternative catalyst to Pt is needed for ZABs and FCs. In recent years, the use of polymer-derived materials for the preparation of nonprecious metal oxygen reduction reaction (ORR) catalysts for ZAB and FC applications has gained a lot of interest. This is due to such properties as high electrocatalytic activity, long-term stability and low-cost.
Dr. Kaido Tammeveski’s group at University of Tartu (UniTartu) has done extensive research in this area and prepared several polymer-based catalyst materials that show good ORR performance. They have also collaborated with Prof. Kurosch Rezwan group from University of Bremen (UniBremen) and a joint paper was published in 2019, where the ceramic polymer materials prepared in UniBremen were studied as ORR catalysts for FC application at UniTartu. Prof. Rezwan group has also necessary equipment and knowledge for ZAB testing, which is currently not available in Tartu. Therefore, the present project gives an opportunity for a researcher from UniTartu to test their catalysts in ZAB at UniBremen. As a result, Estonian-German joint papers are published and the ZAB testing technology for UniTartu is obtained.
