Title: On Disrupting the Na +-Ion/Vacancy Ordering in P2-Type Sodium–Manganese–Nickel Oxide Cathodes for Na +-Ion Batteries

Abstract

An investigation of the electrochemical and structural properties of layered P2-Na 0.62Mn 0.75Ni 0.25O 2 is presented. The effect of changing the Mn:Ni ratio (3:1) from what is found in Na 0.67Mn 0.67Ni 0.33O 2 (2:1) and consequently the introduction of a third metal center (Mn 3+) was investigated. X-ray diffraction ( in-situ and powder) revealed the lack of Na+-ion/vacancy ordering at the relevant sodium contents (x = 0.33, 0.5 and 0.67). The Mn 3+ in Na 0.62Mn 0.75Ni 0.25O 2 introduces defects into the Ni-Mn inter-plane charge order that in turn disrupts the ordering within the Na-plane. The material underwent a P2-O2 and P2-P2’ phase transition at high (4.2 V) and low (~ 1.85 V) voltages, respectively. The material was tested at several different voltage ranges in order to understand the effect of the phase transitions on the capacity retention. Interestingly, the inclusion of both phase transitions demonstrated comparable cycling performance to when both phase transitions were excluded. As a result, excellent rate performance was demonstrated between 4.3 – 1.5 V with a specific capacity of 120 mAh/g delivered at 500 mA/g current density.
