Beam Effects in Synchrotron Radiation Characterization of Battery Materials: X-Ray Diffraction and Absorption Study of LiNiMnCoO and LiFePO Electrodes.

synchrotron radiation-based techniques are a precious tool in battery research, as they enable the detection of metastable intermediates and ensure characterization under realistic cycling conditions. However, they do not come exempt of risks. The interaction between synchrotron radiation and samples, particularly within an active electrochemical cell, can induce relevant effects at the irradiated spot, potentially jeopardizing the experiment's reliability and biasing data interpretation.
