Cationic and anionic migration upon oxidation causing dislocations in oxidized La2LiIrO6. HRTEM image of La2LiIrO6 after 50 cycles, with the corresponding FFT shown in the inset. The atomic migration and IrO2 nanoparticle formation cause a high concentration of defects in the La2LiIrO2 phase. Edge dislocations are shown by T-shaped symbols with dislocations represented by circles. Reproduced with permission.[26]Copyright 2012, American Chemical Society.
