Na3V2(PO4)3 derived cathode materials for sodium-ion batteries (SIBs): A review

Owing to its high energy density, good cycling stability, and abundance of sodium (Na) resources, Na₃V₂(PO₄)₃ (NVP) has emerged as an attractive cathode material for Na-ion batteries (SIBs). However, integrating NVP into composite structures has improved its electrochemical performance markedly. Moreover, by addressing issues related to low electronic conductivity and volume expansion during cycling process, these composite materials have increased lifespan and overall efficiency of SIBs manifold. The review article discussed NVP and its composites with different organic and inorganic materials such as conducting polymers, emphasized the production techniques of these materials and assessed their applicability. Limitations and future scope of NVP-based composites were also discussed in brief. The review summarised the major outcomes of recent research and provided insights into the current developments and difficulties of the sector. It also offers potent resolutions to overcome the limitations in the development of high-performance cathode materials for SIBs.
