Contour maps of the effective electrical conductivity (a)–(c) and the cathode voltage drop (d)–(f) for a range of particle and binder conductivity values at three binder thicknesses. The large arrows on (a) and (d) show how the results change with charging and cycling. (a) Conductivity, 10 nm binder, (b) conductivity, 32 nm binder, (c) conductivity, 100 nm binder, (d) voltage drop, 10 nm binder, (e) voltage drop, 32 nm binder, and (f) voltage drop, 100 nm binder.
