A PVDF/g-C₃N₄-Based Composite Polymer Electrolytes for Sodium-Ion Battery.

ABSTRACT: As one of the most promising candidates for all-solid-state sodium-ion batteries and sodium-metal batteries, polyvinylidene difluoride (PVDF) and amorphous hexafluoropropylene (HFP) copolymerized polymer solid electrolytes still suffer from a relatively low room temperature ionic conductivity. To modify the properties of PVDF-HEP copolymer electrolytes, we introduce the graphitic C₃N₄ (g-C₃N₄) nanosheets as a novel nanofiller to form g-C₃N₄ composite solid polymer electrolytes (CSPEs). The analysis shows that the g-C₃N₄ filler can not only modify the structure in g-C₃N₄CSPEs by reducing the crystallinity, compared to the PVDF-HFP solid polymer electrolytes (SPEs), but also promote
