Kinetic of poly(vinylidene fluoride) defluorination under X-ray irradiation

X-Ray-Induced Changes to Passivation Layers of Lithium-Ion Battery Electrodes

“…e reduction of the C-F signal intensity at 291 eV is likely due to carbonization of sequestered FEC (or its decomposition products [43]) similar to what has been reported for observations on the polymer polyvinylidene fluoride, a very popular binder material for Li-ion electrode fabrication [33,36], upon exposure to soft X-rays [15,16]. In Figure 2, the integrated intensity of each spectrum is plotted against exposure time, and the curves are normalized to the initial observed intensity for each element.…”

“…e MGR and KF models as well as subsequent refinements to the theoretical understanding, including covalent systems [10], neutral fragments [11], lithography [12], defect-electron spreading [13], decomposition [14][15][16][17], and others have helped to maintain ESD/PSD popularity and utility for many years and have motivated the exploitation of the phenomena for various purposes. Urisu and coworkers demonstrated oxygen desorption from molybdenum oxide via synchrotron radiation (SR) as a viable means of surface cleaning [18], and a considerable focus on preferential photochemical reactions highlights the possibilities for deposition and doping in materials engineering applications [19][20][21][22].…”
