Figure 11. TEM and HRTEM images taken after 500 cycles for α-Ni(OH)2 hollow spheres (A, B), β-Ni(OH)2 nanoplates (C, D) and β-Ni(OH)2 nanoparticles (E, F). EIS Nyquist plots of α- and β-Ni(OH)2 nanocrystals before (G) and after (H) 500 cycles. Inset in panel h shows the corresponding Nyquist plot at the high-frequency range. Reproduced with permission.
