Abstract

Electrode Materials In article number 2202137, Kee-Sun Sohn, Tae Joo Shin, Docheon Ahn, Jun Lu, 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).
