Fluoropolymer-Based Nanodielectrics for Energy Storage Application

Growing demand for advanced energy storage systemsAdvanced energy storage system (ESSs) leads to the synthesis of novel materials with the ability to store high-power density and electrical energyEnergy. Film capacitors based on fluoropolymersFluoropolymers like poly(vinylidene fluoride) (PVDF) and its copolymers (PVDF-HFP, and PVDF-TrFe) have enormous applicationsApplications for energy storageEnergy storage portable devices due to high dielectricDielectrics constant and breakdown strengthBreakdown strength with low discharge efficiency. The electroactive structure of fluoropolymersFluoropolymers initiates a micro-capacitance and develops high polarizabilityPolarizability. Thus, this chapter investigates the properties, applicationsApplications, and opportunities of fluoropolymersFluoropolymers with high-energy storage performanceEnergy storage performance. Also, it elucidates the structural dependence due to the inherent polarity (C–H and C–F bond) of polymersPolymer to the dielectricDielectrics constant (charge storage mechanism), ferroelectric polarization, and low leakage current for a high capacitive response. This chapter will mostly stress PVDF, due to its low cost, easy availability, stability, and flexibility for enormous electrical applicationsApplications. The introduction of high k dielectric materialsDielectric materials into polymersPolymer increases their dielectricDielectrics constant, energy storageEnergy storage density, and thermal stability to appreciable value. Therefore, it is essential to investigate the capacitive properties of PVDF-based composites loaded with ceramics and metal oxideMetal Oxide.
