Experimental research data for the article: Solution-combustion synthesis of Na3(VO1-x)2(PO4)2F1+2x as a positive electrode material for sodium-ion batteries

The collection comprises experimental research data obtained during studies on a new method to synthesise sodium-vanadium fluorophosphate as a material to be used in sodium-ion batteries. The obtained powder was thoroughly characterised through non-electrochemical (XRD, SEM, TEM, EDS, N2 adsorbtion/desorption, TGA) and electrochemical (CP, CV, EIS) methods.The dataset, to construct all the figures present in the article, consists of files described in attached README.txt file.
