We have now identified a pyridoxal-based molecule<br \/>\nthat appears to be stable over 50 redox cycles in aqueous media, but at present only at high pH. The key to<br \/>\nthis success lies in protecting one of the anionic groups in the molecule \u2013 without this protection, the<br \/>\nmolecules were unstable irrespective of pH. We are currently expanding on this finding with newly<br \/>\ndesigned molecules that retain the protective group but include groups that should be stable in lower pH.<br \/>\nThe current hypotheses behind the stability issues will be tested with these new materials.<br \/>\nThe JYU team has developed a relatively robust synthetic route to these water-soluble flow battery<br \/>\nmaterials, and is currently also engaged in scaling up the production from milligram to gram scale. Several<br \/>\nbottlenecks and setbacks in the synthesis have been identified and the problems have been circumvented.<br \/>\nWe have also provided materials for the electrochemical testing of the synthesized materials, in<br \/>\ncollaboration with the UTU team. These experiments have provided important and decisive feedback and<br \/>\nthey will now guide our synthetic efforts as they have provided key data on the stability of the materials<br \/>\nunder different conditions. We have also been engaged in developing and expanding the computational<br \/>\nsets with new molecules in WP1 and the most recent additions to these sets include new molecules based<br \/>\non the current hypotheses for stability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Pihko group at JYU focuses on the chemical synthesis of new materials that could be utilized to store energy in flow batteries.
