Table 2. Lattice and total OR capacities quantified through both electrochemical profile and mRIXS-sPFY area changes.

Changes of “O-K mRIXS-sPFY area” indicates the amount of lattice OR (Fig. 3C). Capacity contributions of lattice OR (LOR) is calculated on the basis of sPFY area change with a conversion ratio of 303 mAh/g per area change (see text). The discharge process is dominated by LOR activities; however, LOR capacity during charge is much lower than the electrochemical capacities, indicating a significant amount of non-LOR (nLOR) during charge. a.u., arbitrary unit.
