Development of electrolyte systems
Our main research focus is the electrolyte development of lithium- and sodium ion batteries (LIB/SIB). The research is aimed to increase the battery safety while maintaining or increasing power and energy density. Established electrolyte systems in LIB and/or SIB usually contain highly volatile and flammable organic solvents as well as components that cause burns when in contact with water. To increase the energy density, higher cell voltages are desired. However, the electrochemical stability of standard electrolyte systems is not sufficient for cell voltages above 4.5 V.
