Obtaining V2(PO4)3 by sodium extraction from single-phase NaxV2(PO4)3 (1 < x < 3) positive electrode materials

We report on single-phase Na x V 2 (PO 4 ) 3 compositions (1.5 ≤  x  ≤ 2.5) of the Na super ionic conductor type, obtained from a straightforward synthesis route. Typically, chemically prepared c-Na 2 V 2 (PO 4 ) 3 , obtained by annealing an equimolar mixture of Na 3 V 2 (PO 4 ) 3 and NaV 2 (PO 4 )...
