Can ferroelectric polymers be used for electrical energy storage?
Ferroelectric polymers are attractive candidates as dielectric materials for electrical energy storage applications, but suffer from large dielectric loss. Here, the authors report a method for creating ferroelectric polymer networks with reduced dielectric loss and large charge–discharge efficiencies.
What is a high-energy-density ferroelectric polymer nanocomposite?
Herein, we report a high-energy-density ferroelectric polymer nanocomposite prepared by sandwiching an array of ultra-small metal particles grown in-situ between two layers of ferroelectric polymers (poly (vinylidene fluoride-co-hexafluoropropylene), P (VDF-HFP)).
Why do ferroelectric polymers have a poor charge-discharge efficiency?
However, the high energy loss of ferroelectric polymers leads to a poor charge-discharge efficiency (η), which not only limits the improvement of dischargeable energy density (Ue = η × U), but also generates waste heat to endanger the stability of the capacitor.
How do polymer nanocomposites achieve high dielectric energy storage properties?
The authors realize high dielectric energy storage properties at high temperatures in the polymer nanocomposites via the combined approach of adding high-entropy ferroelectric nanofillers and constructing a bilayer structure.
What is a sandwich-structured ferroelectric polymer nanocomposite?
Here, a sandwich-structured ferroelectric polymer nanocomposite with high energy density is fabricated by sandwiching an array of ultra-small metal particles grown in-situ between two layers of ferroelectric polymers.
Why do ferroelectric polymers have lower discharged energy densities?
While ferroelectric polymers with a normal ferroelectric phase exhibit reduced discharged energy densities (Ud) because of their large remanent polarization Pr (Extended Data Fig. 1a,b), the relaxor ferroelectric phase with minimized Pr can allow much larger Ud and higher charge–discharge efficiency (η; Fig. 1a).
