NASICON-based sodium Fluorophosphate Na3V2(PO4)2F3 (NVPF) cathode materials have been widely analyzed in sodium-ion batteries (SIB) owing to their high energy density and high working voltages. However, the low electronic conductivity of NVPF is a factor hindering their efficient use. To enhance the electronic conductivity of NVPF, a porous Na3V2(PO4)2F3 with Ti3C2-based MXene nanostructures was synthesized using a facile sol-gel method. NVPF acts as a bipolar or symmetric battery material from the presence of two redox couples at a low voltage of 1.4V and another at a high voltage of 3.6~4.1V. The benefits of a symmetric cell are many, including ease of fabrication, low volume expansion leading to higher safety, reduced cost of production, and easy recycling costs. In this work, the MXene-incorporated NVPF are analyzed in a symmetric cell, and the effect of incorporation of various MXene wt. percentages on the structural, thermal, and electrochemical performance of Na3V2(PO4)2F3 in a sodium symmetric cell was thoroughly investigated. Structural analysis of the materials developed indicates that the MXene addition has not altered the crystal structure of the NVPF. The modification improved the electrochemical performance of NVPF in the sodium symmetric cell as indicated by its high specific discharge capacity of 92mAhg-1 at a high C rate of 1C for the MXene 5wt% incorporated composite structures. The GITT analysis confirmed the improved diffusion kinetics of the MXene-incorporated samples, as evident from the calculated Na+ diffusion coefficients. The DNa+ calculated was found to be 9.57x10-9 cm2s-1 for the 5wt% MXene incorporated sample and 4.14x10-9 cm2s-1 for pristine sample.
