Research Progress on Na3V2(PO4)3 Cathode Material of Sodium Ion Battery

Abstract

Sodium ion batteries (SIBs) are one of the most potential alternative rechargeable batteries because of their low cost, high energy density, high thermal stability, and good structure stability. The cathode materials play a crucial role in the cycling life and safety of SIBs. Among reported cathode candidates, Na 3 V 2 (PO 4) 3 (NVP), a representative electrode material for sodium super ion conductor, has good application prospects due to its good structural stability, high ion conductivity and high platform voltage (∼3.4 V). However, its practical applications are still restricted by comparatively low electronic conductivity. In this review, recent progresses of Na 3 V 2 (PO 4) 3 are well summarized and discussed, including preparation and modification methods, electrochemical properties. Meanwhile, the future research and further development of Na 3 V 2 (PO 4) 3 cathode are also discussed.

Environmental Impact Assessment of Na3V2(PO4)3 Cathode Production for Sodium‐Ion Batteries

“…[ 16 ] The initial promising results obtained with Na 3 V 2 (PO 4 ) 3 have sparked notable scientific efforts aimed at improving its relatively poor electronic conductivity of 1.63 × 10 −6 S cm −1 and limited structural stability that result in low discharge capacities (at high rates) and poor operating lifespans.

Na ion batteries: An India centric review

“…It is the main requirement for long cycle life (>20,000 cycles) and storage efficiencies of >90%. New cathode material, like Na 3 V 2 (PO 4 ) 3 (NVP) and its composite, long cycle life (more than 30000), seems to be achievable [99].…”

Validating the Electronic Structure of Vanadium Phosphate Cathode Materials

“…Nevertheless, these earlier studies on K 3 V 2 (PO 4 ) 3 reported similarly promising electrochemical performance and rate capability in potassium- and sodium-ion-based batteries. − With clarification on the primary phase in the KVP analogue, we present detailed analyses for electrochemical performance of K 3 V 3 (PO 4 ) 4 ·H 2 O and relate this and DFT models to surface and structural variations. To date, understanding of vanadium compounds has benefitted from attention to recycling and the life cycle sustainability of vanadium flow and intercalation energy storage materials. − In addition, a significant body of research has been dedicated to the practical optimization of these materials for battery applications through morphology optimization, atomic doping, and conductive coatings/additives. , In contrast, very few studies have been conducted on the comparative electronic structures of LVP, NVP, and KVP. , …”
