NASICON vs. Na metal: a new counter electrode to evaluate electrodes . . . Herein, an alternative counter electrode is devised using NASICON-type Na 3 V 2 (PO 4) 3 to measure the accurate electrochemical behaviour of working electrode materials and to use for measurements above the melting point of Na metal
Highly stable and nanoporous Na3V2 (PO4)3@C cathode . . . - ScienceDirect The electrochemical response of the NVP cathode shows two potential plateaus at 3 4 V and 1 6 V vs Na Na + and a theoretical capacity of 117 mAhg −1 and 50 mAhg −1 depending on the redox reaction of V3+ V 4+ and V 2+ V 3+, respectively [15]
Sodium vanadium phosphate cathode material for Na-ion battery research A standout feature of NVP is its flat voltage profile with a plateau at 3 4 V vs Na Na⁺, which is relatively higher than that of other cathode materials for sodium-ion batteries, providing enhanced energy density
Crystal structure and electrochemical properties vs. Na We further examined the Na + insertion mechanism of this phase whose signature was similar to the one of “NaVPO 4 F” and “Na 3 V 2 (PO 4) 2 F 3 ” Namely two voltage plateaux are found at 3 6 and 4 0 V vs Na + Na and are characteristics of two bi-phasic transitions
Computational Study of NaVOPO4 Polymorphs as Cathode Materials for Na . . . Phosphate compounds are promising materials for sodium-ion batteries because of their high structural stability Vanadium phosphates have shown high energy densities as cathode materials, but their Na-ion transport and cation-doping properties are not as yet fully understood
