The Na 3 V 2 (PO 4 ) 3 (i.e. NVP) is a Natrium Super-ionic Conductor (NaSICON) type compound which provides a 3D open framework that has strong covalent bonds, making this material a promising cathode material with high-power density. Increasing its ability to deliver Sodium-ion at a faster rate and...
