Abstract

The rising needs to develop high-performance energy storage systems fuelled us to rationally design a system of frameworks Na5M(PO4)2F2 (M=Cr, v), which can find use as Superionic cathode materials for Sodium Ion Batteries.
The findings of the work provide a theoretical basis with respect to their thermodynamics as well as Na ion migration kinetics. In addition to DFT studies, we have also performed Ab-Initio Molecular Dynamics simulations to obtain a more realistic understanding of the systems at finite temperatures.
We believe that this work is novel and has contemporary relevance.
