thickness. XRD pattern is composed of peaks solely attributed to orthorhombic α-S8 phase (PDF-2; no. 00-008-0247), which was used for electrodes preparation. It may be expected that carbon fibers introduced to the composite electrode in the form of current collector participate in the discharge process, by offering a conductive area for solid products deposition. SEM photos recorded on the electrode at the end of 1st discharge are shown on Figure 3-5. The electrode was carefully rinsed with TEGDME/DIOX (50/50 vol%) mixture of solvents under protective atmosphere in the glove box, in order to remove the lithium salt (LiTFSI) and eventual traces of soluble polysulfides. After solvent evaporation, the cross section was made with the scissors and the piece of electrode was placed on SEM sample holder inside the air- tight transfer box, as previously shown on Figure 2-3a,b. Such solution allowed to keep the sample without exposure to air. Figure 3-5. SEM photos of ‘S-on-NwC’ electrode after initial discharge: cross-section view (a,b) with zoomed image on a single carbon fiber (d), and on the dense thin layer deposited on its surface (e,f). Air- sensitive sample was totally protected from air atmosphere thanks to transferring in a special box designed for that purpose (‘transfer box’). An image of fresh carbon fiber is also shown for comparison (c). Chapter 3: S8 electrode on NwC 77PDF Image | Accumulateur Lithium Soufre
