| Popis: | This paper gives a brief review of the application of synchrotron X-ray techniques to the study of lithium-ion battery materials. The two main techniques are X-ray absorption spectroscopy (XAS) and high-resolution X-ray diffraction (XRD). Examples are given for in situ XAS and XRD studies of lithium-ion battery cathodes during cycling. This includes time-resolved methods. The paper also discusses the application of soft X-ray XAS to do ex situ studies on battery cathodes. By applying two signal detection methods, it is possible to probe the surface and the bulk of cathode materials simultaneously. Another example is the use of time-resolved XRD studies of the decomposition of reactions of charged cathodes at elevated temperatures. Measurements were done both in the dry state and in the presence of electrolyte. Brief reports are also given on two new synchrotron techniques. One is inelastic X-ray scattering, and the other is synchrotron X-ray reflectometry studies of the surface electrode interface (SEI) on highly oriented single crystal lithium battery cathode surfaces. |
