A comprehensive overview of the measurements and analyses available with Malvern Panalytical's multipurpose X-ray diffractometers and software solutions.
This webinar will focus on the development and application of a new X-ray diffraction (XRD) technique for in situ / in operando measurements of lithium ion batteries. Using hard X-radiation (e.g. Mo) the sample battery cells can be set up in transmission geometry. This type of X-ray source offers enough penetration depth to allow measurement of thin pouch or coffee bag type battery cells, which are commonly used in laboratories as prototype cells for mass production and are therefore of great interest to be studied without cell tampering. The method is shown in an example of an aging study on graphite // Li-NMC cells cycled at different cutoff voltages and temperatures.
