Impact of Transition Metal Layer Vacancy on the Structure and Performance of P2 Type Layered Sodium Cathode Material.

ABSTRACT: This study explores the impact of introducing vacancy in the transition metal layer of rationally designed Na_0.6[Ni_0.3Ru_0.3Mn_0.4]O₂ (NRM) cathode material. The incorporation of Ru, Ni, and vacancy enhances the structural stability during extensive cycling, increases the operation voltage, and induces a capacity increase while also activating oxygen redox, respectively, in Na_0.7[Ni_0.2V_Ni0.1Ru_0.3Mn_0.4]O₂ (V-NRM) compound. Various analytical techniques including transmission electron microscopy, X-ray absorption near edge spectroscopy, operando X-ray diffraction, and operando differential electrochemical mass spectrometry are employed to assess changes in the average oxidat
