Fig. 11.5 Voltage profiles over the first cycle of pure silicon, a mixture of silicon-graphite, and a carbon-coated silicon-graphite. In all cases, the composite electrode contained 10 wt% PVDF and the silicon particle grain size was in the range of 1-5 pm. Degrees of silicon lithiation for samples presented in the figure were roughly the same and could be estimated by the simulation given in Fig. 11.4.
