It has been reported that P-type materials show better electrochemical performance compared with O3-type compounds, while P2-structures exhibit better performance than P3-types 10. 9, sodium-based layered oxides can be divided into two main types: O3-type and P2-type, which correspond to the arrangement of sodium ions at octahedral (O) and prismatic (P) sites with the appended number illustrating the number of MO 2 layers per unit cell. According to the notation by Delmas et al. They consist of stacked sheets of edge sharing M-O 6 octahedra. The most extensively studied group is layered oxides of NaMX 2-type. These can be categorized into three groups: layered oxides, polyanionic frameworks, and prussian blue analogues 3, 4, 5, 6, 7, 8. Various cathode materials have been proposed for SIBs, mirroring research approaches for LIBs.
Therefore, sodium-ion batteries (SIBs) represent a good alternative in terms of cost-effectiveness and sustainability especially when the energy density is not the most important parameter, for example in stationary applications 2. However, there have been concerns about the Li resources which could be exhausted with the increased demand 1.

Rechargeable lithium-ion batteries (LIBs) have become key components in portable electric devices as well as in the automotive industry as a result of their excellent energy and power capability compared with other battery systems.
The increasing use of electronic devices results in a higher demand for energy storage technologies.
