Dynamic X‐Ray Diffraction

The discharge of a electrode in an ambient temperature organic electrolyte cell has been investigated by dynamic x‐ray diffraction. The new technique involves a continuous in situ measurement of x‐ray diffraction simultaneous with electrochemical polarization. The investigation has provided additional information on electrolithiation of . These include: ( i ) the onset of changes in 101 peak position right from the start of discharge, ( ii ) correspondence of in to state‐of‐charge from coulombic balance; and ( iii ) details of changes in the c axis during discharge, especially during the first 30% of discharge capacity. The results are discussed along with the cell design, operational details, and merits and limitations of the technique.
