30th Seminar of the Working Group Electrochemistry in Saxony

On February 7, 2020, the Working Group Electrochemistry in Saxony (AKES) met for its 30th Seminar at the TU Bergakademie Freiberg. For the first time Tilmann Leisegang was the host.

The Working Group Electrochemistry in Saxony (AKES – Arbeitskreis Elektrochemie in Sachsen) met for its 30th Seminar at the TU Bergakademie Freiberg. Tilmann Leisegang, principal investigator for Energy Materials at the Institute of Experimental Physics (IEP) and member of the AKES since January 2020, organized this meeting together with Rudolf Holze, the founder and organizer of AKES.

Representatives of the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) and Technology Center Semiconductors (THM), the Institute for Chemistry (Electrochemistry) of TU Chemnitz, the Kurt-Schwabe-Institute Meinsberg as well as the Institute for Inorganic Chemistry (Salt and Mineral Chemistry) and the IEP (Energy Materials) of the TU Bergakademie Freiberg contributed to the program. Topics such as electrochemical materials science, electrochemical energy converters, and electrochemical analytics were covered.

After a joint welcome coffee in advance, the 30th seminar began with a welcome from Rudolf Holze and Tilmann Leisegang. During the morning session, the determination of lithium diffusion coefficients and wetting properties studied with impedance spectroscopy, the assembly of 3-electrode lithium-ion test batteries, the electrochemical deposition of battery electrodes, the improvement of the liquid electrolyte for aluminium-graphite batteries as well as all-solid-state electrodes for environmental analysis were presented. During the subsequent lunch break with its delicious catering, all participants had the opportunity to further discuss the presented topics. In the afternoon session, biopolymer all-solid-state electrodes for environmental analysis, pulse-voltammetry for the identification of redox processes in polymers, electrodes for the electrochemical detection of pyrene, and new solid ion conductors for beyond-lithium batteries were discussed. The meeting was concluded with conclusive remarks by Rudolf Holze and a joint final coffee and teatime. Afterwards Tilmann Leisegang guided through the laboratories of the IEP.

The Working Group Electrochemistry was founded at a first meeting in Chemnitz on 16.06.1995 by Rudolf Holze as an open platform for electrochemists and surface scientists in universities, research institutions, and in industry. It serves the transfer of knowledge, the exchange of experience and information about events, trends, and new possibilities. 

The AKES and Tilmann Leisegang thanks all participants for their stimulating contributions and discussions, Robert Schmid (IEP), Reiner Krönert (URZ), essbar Freiberg for their organizational support, and the Universitätsrechenzentrum for hosting.
