Energy storage performance of Na0.5K0.5NbO3-P(VDF-TrFE) lead-free composite films

Abstract

The lead-free Na0.5K0.5NbO3-Poly(vinylidene fluoride-trifluoroethylene) (KNN-P(VDF-TrFE)) composite films were prepared by sol-spin coating method. The KNN film was annealed at 700 °C for 3 min with the P(VDF-TrFE) film annealed then at 160 °C for 2 h. The ferroelectric and energy storage properties of composite films were also investigated. The energy storage density of the composite films reached 7.58 J/cm3, and the efficiency was 52%. In addition, the KNN-P(VDF-TrFE) composite films showed weak leakage behavior.

(a) Schematic diagram of the composite films. (b) P-E hysteresis loops of KNN-P(VDF-TrFE) composite films with different film layers and concentration of P(VDF-TrFE) at 1 kHz, the annealing process was 160 °C for 2 hours. “K/0.02 P × 1” means “KNN-1 layer of P(VDF-TrFE) composite films, and the solution is 0.02 g/ml”. (c) Leakage current density of composite films at 1000 kV/cm.

Highlights

  • The P(VDF-TrFE) (Poly(vinylidene fluoride-trifluoroethylene)) films were annealed at different temperatures and characterized by Integrated Ferroelectric Measurement System and then get the storage density of 3.30 J/cm3 at the η = 33%.

  • The 2-2 KNN-P(VDF-TrFE) composite films were prepared to get high energy storage density for the first time.

  • The ferroelectric and energy storage performance of KNN-P(VDF-TrFE) composite films were studied and the storage density can reach 7.58 J/cm3 at the η = 52%.
