Figure 3.

1st discharge capacity values plotted against the sulfur loading (a–c) or the cathode coating thickness (d–f) in EMIMCl–AlCl₃ (a, d), acetalumina (b, e) and uralumina (c, f). The black square symbols show the results obtained with the electrodes coated on a thicker (25 μm) Mo foil, whereas the red circles show the results using a thinner (10 μm) Mo foil. In both cases, the electrodes contain 60 % sulfur and CNT as the only carbon source. The blue triangles show the results of electrodes made with a small amount (1–8 %) of other carbon additives mixed with CNT.
