July 2018The two pictures show the chamber inside of our new Xe plasma FIB SEM (XEIA3, Tescan) and the preparation process for the cross section of a zinc sponge which incorporates an ionomer. At first, a trench was made with the highest milling rate in about 2 hours, followed by polishing with two successive steps of an intermediated and a low milling rate for about 1 hour. The cross section shown is the first cross section made in our new FIB SEM. The sample was investigated within Project Zisabi (in cooperation with Prof. Abe, Kyoto University, Japan; funded by the German Federal Ministry of Education and Research), where we look at the influence of anion-exchange ionomers on structured zinc anodes to stabilize the electrochemical deposition and dissolution processes during cycling.For more information, please contact Boris Mogwitz and Klaus Peppler.
