Extended Data Fig. 10 | Gradual loss of ribbon superstructure ordering from
diffraction. Ex situ PXRD patterns for Na0.6[Li0.2Mn0.8]O 2 in the discharged
state (2.0 V) after 1, 10 and 20 charge–discharge cycles (between 2.0 V and 4.5 V
at 10 mA g−1). Peaks arising from the periodicity uniquely along the c-axis
remain sharp upon cycling (indexed as 002 and 004 according to the P 63 /mmc
space group without superstructure), whereas all other peaks, especially the
010 and 110, which are unique to ordering within the ab plane, broaden and
reduce in intensity as the ribbon superstructure is lost on cycling.
