Operando study of lithium batteries Lithium battery materials evidence redox processes and structural changes directly related to the electrochemical performances: energy, capacity, reversibility and life time. Many characterization techniques are used in order to explain the general behaviour. Most of them are only operating after equilibrium of the battery, and even after withdrawal of the material under study. This paper shows how the high performances of synchrotron sources allow the materials characterization during the functioning of the battery, in using X-ray diffraction and absorption. In doing so, it is possible to directly correlate the structural and electronic characteristics of an electrode and its electrochemical performances.
