Figure 7. Electrochemical performances: (A) Comparison of cyclic performance among PV nano-Si electrodes (PV nano-Si-1h, PV nano-Si-3h, and PV nano-Si-9h) with CMC binder at 0.03C current rate; (B-D) Corresponding discharge-charge voltage profiles of the PV nano-Si electrodes; and (E) Cyclic performance comparison between PV nano-Si-3h and commercial nano-Si electrodes with CMC-PAA binder at 0.03C current rate.
