In a joint project of the Austrian Institute of Technology GmbH (AIT), AVL List GmbH, PE CEE Nachhaltigkeitsberatung & Software Vertriebs GmbH and ICTM the advancement of Lithium-air batteries was pursued. Starting in January 2014 (end in December 2017) the project partners aimed at evolving a bimodal Li-air battery with optimized cell components, which is applicable in future electric vehicles. To achieve this goal, three main targets have been set: optimized design of the Li-air cathode, development of suitable bifunctional catalyst and optimization of the electrolyte system.
In this context, ICTM was developing a porous oxidation stable cathode material building on the expertise of carbonizing polyDCPD foams (Slugovc, C. et al. Eur. Pat. Appl. 2012, EP 2669260 (A1)) and, as a second task, polymeric electrolytes.
Dr. Bettina Schafzahl and DI Aleksej Samojlov worked on these topics.
