Minimization of the parasitic scattering from the current collectors. (a) X-ray transmission for carbon, PEEK, Al and stainless steel current collectors as a function of the scattering angle. The percentage change between low and high angle is given in the graphs. The X-ray transmission is given as a function of the distance of the beam from the current collector (Δx, as shown in the inset) when the beam is at the edge of the current collector: 100 µm, 500 µm and 1 mm away from it (from dark to light shades, respectively). (b) Total scattering data, Q × S(Q); and (c) PDF data for glassy carbon collected with carbon (blue), PEEK (green), Al (purple) and stainless steel (red) current collectors. |
