The figures are as follows:

Figure 1: Polymerisation of acrylonitrile via an electro-reduced superoxide anion species [28].

Figure 2: (Left) Cyclic voltammogram for the electrodeposition of PAN onto a graphite battery electrode of 14 mm diameter using acrylonitrile electrolyte (0.05 mol dm-3 [Bu4N][ClO4]) saturated with O2. Deposition was performed at a scan rate of 50 mV s-1 from 0 to -3.5 V vs. Ag for 5 cycles. (Right) Photo of the graphite electrode after the PAN electrodeposition, showing that the PAN is transparent.

Figure 3: SEM image of electrodeposited PAN on a graphite battery electrode. The electrodeposition conditions are as described in Fig. 2.

Figure 4: Raman spectra of: electrodeposited PAN on a graphite battery electrode (top), the uncoated graphite battery electrode (middle) and PAN powder purchased from Sigma-Aldrich (bottom). The electrodeposition conditions for PAN are as described in Fig. 2.

Figure 5: Thermogravimetric analysis of the electrodeposited PAN, commercial PAN power and the components of the graphite battery electrode (graphite, carbon conductive additive and PVDF binder). The temperature was ramped at 2 oC min-1 from 25 to 250 oC. The annotated purple dotted lines give key temperatures and mass loss of the PAN electrodeposited sample at each temperature. PAN was electrodeposited on copper at -3.0 V vs. Ag for 100 s.

Figure 6: Mass of 14 mm diameter PAN electrodeposits on graphite battery electrodes via the application of a constant electrodeposition potential for 100 s via chronoamperometry experiments, plotted as a function of the electrodeposition potential. All other conditions are as in Fig. 2.

Figure 7: Mass of 14 mm diameter PAN electrodeposits on graphite battery electrodes via the application of a constant electrodeposition potential of -3.0 V vs. Ag for various timescales, between 0.5 and 100 s, and plotted as a function of the charge passed. All other conditions are as in Fig. 2. A linear fit with fixed zero intercept is included in the graph, and the corresponding equation is also included.

Figure 8: Thickness of 14 mm diameter PAN electrodeposits on graphite battery electrodes, plotted as a function of the mass of PAN electrodeposits. All other conditions are as in Fig. 2. A linear fit with fixed zero intercept is included in the graph, and the corresponding equation is also included.

Figure 9: Results of the galvanostatic cycling at C/10 of uncoated (top) and PAN coated (bottom) graphite electrodes in lithium half-cells containing LP57 electrolyte (1 M LiPF6 in EC:EMC 3:7) at 25 °C. Conditions of PAN electrodeposition were using chronoamperometry at -3.0 V vs. Ag as in Figs. 7-8. The thickness of the PAN electrodeposit is 32 µm.

Figure 10: Delithiation capacity of uncoated and PAN coated battery electrodes as a function of the cycle number, as measured in lithium half-cells. All conditions as in Fig. 9.

Figure 11: Delithiation capacity of uncoated and PAN coated battery electrodes as a function of the cell temperature. Two galvanostatic cycles were performed at each temperature, and the cell temperature was controlled by hosting the cells inside an oven. All conditions as in Fig. 9.
