Soft X-ray Characterization Technique for Li Batteries under Operating Conditions



Daniel A. Fischer, Cole Petersburg, Robert Daniel, Cherno Jaye, Faisal Alamgir


O K edge and Co L edge near edge X-ray absorption fine structure (NEXAFS) was used to examine the cathode of an intact solid-state lithium ion battery. The novel technique allowed for the simultaneous acquisition of partial electron yield and fluorescence yield data during the first charge cycle of a LiCoO2-based battery below the intercalation voltage. The chemical environments of oxygen and cobalt at the surface are shown to differ chemically from those in the bulk. The present design enables a wide variety of in situ spectroscopies, microscopies, and scattering techniques.
