Research on PVDF-based electrolytes for dual-ion batteries

Abstract

The production of new batteries and their application are becoming more and more important as the world's energy demands and environmental stress increase. Due to their long lifespan, high energy density, and affordability, dual-ion batteries have garnered a lot of attention as a novel battery type in recent years. When compared to other conventional electrolytes, PVDF-based polymer electrolytes with high conductivity and superior mechanical qualities greatly enhance battery performance. Therefore, a comprehensive analysis of the techniques for enhancing the characteristics of electrolytes based on PVDF is presented in this study. The statement demonstrates how a smooth surface can improve the stability of electrochemical processes and raise ion conductivity. Moreover, ion transport rate, capacity, energy density, and duration of cycle of dual-ion batteries can all be markedly increased by strengthening structural stability and adding inorganic fillers. These measures can provide useful references for the optimization and improvement of dual-ion batteries and promote their application in electric vehicles and energy storage area.
