AB  - Herein we report on an analytical approach for targeted identification of hazardous 1,3-propane sultone (PS) in spent lithium ion battery material. PS decomposition is investigated with chromatographic techniques coupled to high-resolution accurate mass spectrometry. Speciation of sulfur-containing decomposition products is performed and aging marker molecules are defined. The observed PS decomposition results in characteristic 1-propanesulfonate via electrochemical ring-opening. Based on this, 1-propanesulfonate is defined as an ionic marker molecule for electrochemical PS decomposition. Further, volatile methyl and ethyl esters of 1-propanesulfonate are identified. Their formation is observed mainly caused by elevated temperatures after preceding PS ring-opening during cell formation. Both, ionic and volatile decomposition markers can be applied for targeted identification of hazardous PS-containing lithium ion battery material, despite possible consumption of the initial additive molecule.
