The development of rechargeable Lithium-Ion batteries has revolutionized the way how we store energy and allows the use of small portable electronics for work, communication and entertainment. It is recognized as key technology enabling long range electric vehicles.[1] In a close collaboration with the Münster Electrochemical Energy Technology department we are developing novel film forming additives on the basis of small organic molecules that protect anode and cathode materials in Lithium-Ion batteries. By this we aim to allow for longer battery lifetimes, higher charging rates and increased cell voltages. Key to success is the formation of highly efficient passivation layers on the electrodes that allow Li+ transportation but block electrons to prevent electrolyte decomposition.[2]
