Experimental Investigation of the Influence of the Electrolyte Composition on the Ageing Behavior of Separators in Lithium-Ion Cells
In this contribution, the decomposition reaction mechanisms are evaluated under a number of different thermal conditions for various commercial electrolytes from automotive lithium-ion cells. Furthermore, their influences on the ageing behaviour of different separator types are investigated. Details of the experimental procedure, analytical methods (NMR, GC-MS, SEM/EDX) and first results will be presented. Finally, we will give an overview of our mechanistic interpretation.
