This content is a preprint and has not undergone peer review at the time of posting.


As a chemically and structurally well-defined model for redox processes in the solid electrolyte interphase of battery electrodes, we investigate electron transfer to lithium ions at the interface between a platinum metal anode and a solid polymer electrolyte. Studied electrolytes include LiTFSI (lithium bis(trifluoromethane)sulfonimide) salts in polyethylene oxide and poly(diethylene oxide-alt-oxymethylene), as well as in the as- sociated liquid electrolytes 1,2-dimethoxyethane and tetraglyme.
