depicted in Fig. . Since the intergrowth phase was observed next to the parent phase, the 1:1 periodic structure can be interpreted as the opposite of Daumas-Hérold type ordered staging proposed for intercalation processes . To summarise, residual Cu/Li intercalants were present in extremely diverse conditions, including not only regions of the parent-type I4/mmm structure but also its intergrowth with the collapsed type slabs.
