It is remarkable that materials calcined via such dramatically differing pathways can exhibit such similar electrochemical behavior. However, the structural differences between the SL-LMR and LL-LMR primarily relate to the extent of monoclinic character and the superstructure present. Superstructure in LMR materials is often lost as part of the substantial atomic rearrangements that accompany electrochemical activation. It follows that any electrochemical properties that arise directly from the presence of highly ordered Li 2 MnO 3 -like domains would disappear as these domains are lost over cycling. We conclude, as has been discussed before that increased Li 2 MnO 3 -like character results in a transient increase in capacity, particularly in the anionic redox region on first charge.
