In commercial batteries, a carbon-containing material (e.g. synthetic graphite) and a lithium metal oxide are usually used for the two differently charged electrodes, while a conductive lithium salt - dissolved in a mixture of organic solvents - serves as the electrolyte.<\/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

The aim of the materials research field is to identify new materials with potentially higher energy densities that are safe and can be produced at lower costs. In addition, these should enable rapid charging and discharging over many cycles. A new development or optimization of both the electrode and the electrolyte materials is necessary.<\/p>\n

In order to achieve high energy and power densities, the members of the group research to minimize or completely eliminate undesired chemical reactions at the interface between electrode and electrolyte. The development of suitable syntheses is in the foreground for the new materials, since the process control has a strong influence on the technical properties of a material, e.g. the charging cycle stability.<\/p>\n

Another focus in this research field is the development of completely new battery concepts (e.g. magnesium battery). These have the potential to achieve significantly higher storage capacities than all previously known concepts.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
