Aqueous sodium ion batteries are future low cost and eco-friendly energy storage systems, but aqueous batteries are very much constrained by the electrolyte degradation. In this aspect, we have evaluated effect of salt concentration and electrolyte additives on aqueous sodium ion full cell performance by using NaTi2(PO4)(3) and Na3V2O2X(PO4)(2)F3-2X as anode and cathode materials respectively. Before making full cell, the effect of adding different concentrations of vinylene carbonate (VC), carboxymethyl cellulose (CMC) and agarose (Ag) to aqueous 10 M NaClO4 electrolyte was correlated by using cathode material in half-cell configuration. In full cell, 10 M NaClO4 electrolytes with 2 v% of VC enhances the cycle stability of NaTi2(PO4)(3)-C//Na3V2O2X(PO4)(2)F3-2X-MWCNT systems compared to other electrolytes.
