Figure 6
Scale of oxyanion-dependant changes in domain size for the amorphous cobalt oxide OEC. The LiCoOO form of model 1 was used for fitting the domain dimension for the CoPi. Models 4 and 5 provide the scale of domains corresponding to the CoMPi and CoBi OEC, respectively. In addition, as described in the text, the increase in the domain size for CoMPi and CoBi was correlated to increases in the extent of disordered layer stacking, with limited stacking coherence length, corresponding to mixtures of monolayers, dimers and trimers.
