1. General Introduction

This directory contains raw data and scripts used to reproduce the analysis performed in the study titled: Compositional Flexibility in Irreducible Antifluorite Electrolytes for Next Generation Battery Anodes. The data and analysis are related to the investigation of lithium-ion conduction in antifluorite-type materials, with implications for next-generation battery anodes. The dataset is publicly available for further research purposes and to support the reproducibility of the publication.


2. Description of Files in this Directory

Bottleneck_size_calculations/:

3. Methodological Information

Data Collection and Processing Methods

Molecular Dynamics (MD) Simulations:

MD simulations were conducted using VASP (version 5.4), with the results stored in vasprun.xml and processed using Python scripts to analyze bottleneck sizes, lithium jumps, and relative site energies.


Experimental Data:

Linear Sweep Voltammetry (LSV) and X-Ray Diffraction (XRD) data were collected using commercially available instruments, and the results were processed using Python scripts and Microsoft Excel for temperature-dependent fitting.


Software Used

VASP (version 5.4): Used for MD simulations.

Python (version 3.10): Required to run the analysis scripts.

Microsoft Excel: Used for fitting Arrhenius plots.
