Understanding the redox process upon electrochemical cycling of the P2-Na_0.78Co_1/2Mn_1/3Ni_1/6O₂ electrode material for sodium-ion batteries.

ABSTRACT: Rechargeable sodium-ion batteries have recently attracted renewed interest as an alternative to Li-ion batteries for electric energy storage applications, because of the low cost and wide availability of sodium resources. Thus, the electrochemical energy storage community has been devoting increased attention to designing new cathode materials for sodium-ion batteries. Here we investigate P2- Na_0.78Co_1/2Mn_1/3Ni_1/6O₂ as a cathode material for sodium ion batteries. The main focus is to understand the mechanism of the electrochemical performance of this material, especially differences observed in redox reactions at high potentials. Between 4.2 V and 4.5 V, the material delivers a reversible capacity which is studied in detail using advan
