| Abstract | The invention of solid electrolytes appears to be cutting-edge technology for the battery system as they conquer the majority of the issues associated with liquid electrolytes. However, the most significant constraints for solid electrolytes are poor ionic conductivity and inadequate power density. In the current study, an initiative is being taken to enhance the ionic conductivity of solid electrolytes. In this view, several samples of solid electrolytes are prepared by differing the proportion of PVDF and PEO; also, NaNO3 is utilized as a conductivity booster in various ratios. Due to numerous advantages, the cast solution technique is opted to prepare all the examined electrolytes. Further, the homogeneity of all the substances existing in the electrolytes is observed with XRD. Also, all the ready samples' ionic conductivity and dielectric constant are tested to analyze their performance in lithium-ion batteries. A homogeneous bonding between PVDF and PEO is observed in the electrolyte matrix, but the presence of NaNO3 is not observed thoroughly. The ionic conductivity of all samples looks stable and increases with the concentration of NaNO3 in the compound matrix. Therefore, it is being concluded that using NaNO3 in the PVDF-PEO-based polymer electrolytes has favorably impacted conductivity and stability. The current research is a reasonable attempt to improve the ionic conductivity of PVDF-PEO-based electrolytes with one-of-a-kind proportions. |
