Regulating Sodium Storage Sites in Carbon Materials via Fluorine doping for Sodium Ion Batteries

Key Points

• The aim is to improve sodium storage sites in carbon materials through fluorine doping to enhance sodium-ion battery performance.
• Fluorine doping of carbon materials
• Characterization of sodium diffusion kinetics
• Assessment of volume changes during sodiation/desodiation
• Fluorine doping significantly enhances Na+ diffusion rates
• Reduced volume changes observed during charge and discharge cycles
• Improved overall performance of sodium ion batteries
