Enabling in operando batteries measurement at D19 beamline
The Li-ion chemistry is thus far the most advanced chemistry employed in battery technology. To date, Li-ion batteries dominate the market of the electronics and portables devices. However, in the field of electric and hybrid vehicles further improvements are required in terms of performance, safety, and cost. High voltage cathode materials such as LiNi0.8Co0.1Mn0.1O2 (hereafter called NMC811) are suffering drastic volume changes and enhanced structural degradation caused by the Li insertion/de-insertion. Understanding the extend of the structural degradation during cycling will be an asset to improve the overall electrochemical performance. In operando measurement are thus crucial but it requires several days at beamline quite often saturating the beamtime demand. Here we identified that the D19 beamline generally used for single crystal diffraction on molecular and structural biology samples could be tuned to welcome batteries users and in operando measurement if some modifications at the beamline are undertaken. It will drastically increase the ILL capacity in term of battery investigation in the next future.
