The goal in the project "MagSiMaL" is: to generate a highly cycle stable and rate capable Magnesium-Sulfur-Battery, which involves cathode materials with a high content of covalently bound sulfur; to synthesize new conductive salts and electrolytes, which are stable in a broad electrochemical window and are (beside desired SEI formation) chemically and electrochemically inert. Furthermore, a strong emphasis lies on the clarification of aging mechanisms inside Mg-S-cells and their single components (anode, cathode, electrolyte) by using post-mortem analysis techniques. Finally, the influence of different morphologies as well as surface activation of Mg-anodes on their electrochemical response is to be investigated in this project."
