“…Another efficient method to construct hierarchically structured porous NVP microflowers is to employ surfactants (e. g., sodium oleate, oleic acid, hexadecyltrimethylammonium bromide, and sodium dodecyl sulfonate) as the structuredirecting agent, which can regulate the nucleation and growth process of NVP precursor to form the primary nanoflake-like precursors. [43][44][45][46][47] The evolution mechanism from the nanoflakelike precursors to hierarchical microflowers conforms to the Ostwald ripening process. Cao et al, [43] developed a solid-state reaction approach to synthesize the 3D graphene decorated NVP nanoflakes (NVP-NFs) using paraffin wax as the nonpolar solvent and oleic acid as the structure-directing agent.…”

Na 3 V 2 (PO 4 ) 3 (NVP) has been regarded as a potential cathode material for sodium-ion batteries (SIBs) due to its excellent structural stability and rapid Na + conductivity. However, its electrochemical performances are restricted by the large bulk structure and poor electronic conductivity. The construction of porous NVP materials is a powerful method to improve the electrochemical properties. This concept aims to provide an overview of recent progress of porous NVP materials for SIBs. Herein, the synthetic strategies and formation mechanisms of porous NVP materials as well as the relationship between the porous structures and electrochemical performances of NVP materials are reviewed. Furthermore, the challenges and prospects for the preparation of porous NVP materials in this field are outlined.

“…In the work, NVP was synthesized by an easy calcination method that can be scaled for large production. Another material with NVP and in situ carbon layers (NVP/C‐T), which develops into a 3D skeleton structure developed by Ling et al, 7 also performs well in high C rates and shows improved stability with a value of 70.1 mAh g −1 at 2C after 200 cycles with a columbic efficiency of 98.6%. Similar to these, various other studies were carried out such as in situ carbon layers combined with NVP giving a 3D skeleton structure, carbon layer combined with nitrogen (N) doped graphene Aerogel (NVP@C/N‐GA), double carbon embedding on NVP (DC‐NVP).…”

The development of efficient energy storage systems is an important field of research in the modern era where fossil fuels are headed toward depletion. The invention of batteries is regarded as one of the most significant advancements in the field of energy storage. From its inception, a lot of research has been done and is still being carried out to develop novel and advanced materials that provide improved performance in terms of capacity, stability, and cost. In this context, symmetric or bipolar electrodes, which utilize the same material for the anode and the cathode, emerge as a suitable solution for battery technology. In this work, different types of symmetric electrode materials for batteries are subjected to review. The various structures, methods of synthesis, and characteristics are analyzed and presented. The Na 3 V 2 (PO 4 ) 3 (NVP) is the most widely analyzed symmetric material among all the symmetric materials. The Na-based systems are widely studied in symmetric configurations for their resource availability and price economics advantages. Aqueous and solid-state symmetric batteries are the emerging systems in symmetric batteries. This review will provide insights to battery researchers involved in bipolar material design and shed light on new emerging energy storage techniques.

“…Most of the previous reports on symmetric full cells have focused only on the modication of NVP cathodes. [12][13][14][15] Even though the NVP cathode possesses superior characteristics in terms of the structural stability and reaction mechanism, the material's low electronic conductivity limits its electrochemical performance. 10 Previous studies have tried to overcome this drawback by adopting doping strategies and utilizing conductive carbon matrices.…”
