The development of new batteries with high energy densities, faster kinetics, higher stability and safety requires targeted basic research. To do this, it is necessary to determine which reversible electrochemical processes take place at high cell voltages and currents. When a battery is discharged, stored chemical energy is converted into electrical energy by so-called electrochemical redox reactions (transfer of electrons during the reactions).<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

In the research field of electrochemistry, the scientists examine, among other things, the interfaces between the electrode (electron conductor) and electrolyte (ion conductor), where the battery-specific redox reaction takes place. The focus is on the structure of the interface down to the atomic level in order to understand the electrochemical processes and interactions occurring therein. The aim is to use models to record the processes in real energy storage systems and thus derive improvement approaches for the efficiency and stability of batteries. At the same time, alternatives to conventional lithium are being tested in order to create the basis for the battery type for the next generation and beyond.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
