Unravelling the Nature of the Intrinsic Complex Structure of Binary-Phase Na-Layered Oxides
In article number 2202137, (Adv. Mater. 29/2022) A K Paidi, Docheon Ahn and co-workers report an in-depth phase analysis of their developed Na1−xTMO2 cathode materials with P2- and O3-type phases for Na-ion rechargeable batteries, providing structural visualization on an atomic scale and unveiling the existence of a mixed-phase intergrowth layer distribution and unequal distribution of P2 and O3 phases. The synergetic effect of the simultaneous existence of P- and O-type phases and their unique structures allows an extraordinary level of capacity retention in a wide range of voltage (1.5–4.5 V).
