Abstract

In this work, we have explored the iron-based mixed polyanion cathode material for sodium-ion thin film batteries. Thin films of mixed polyanion compound Na4Fe3(P04)2P207 has been prepared by pulsed laser deposition (PLD). The bulk powder was synthesized by facile solution combustion synthesis and it crystallized into orthorhombic structure with Pn2/a space group as confirmed by Rietveld refinement. The observed galvanostatic charge/discharge profiles of the thin film cathodes are characterised by features similar to those measured for the bulk powder samples. Thin film Na4Fe3(P04)2P207exhibited reversible Na+ storage capacities in the range of 110-120 mAh g"1 for more than 100 cycles with various thickness of the thin film electrode.
