    Published 2025-01-01
    “…Excitingly, an ultra-high discharged energy density of 25.0 J cm−3 and a large efficiency of 81.2% are achieved in Na0.5Bi4.5Ti4O15-poly(vinylidene fluoride-co-hexafluoropropylene)/Na0.5Bi4.5Ti4O15-polyetherimide bilayer composites under a dramatically enhanced breakdown strength of 8283 kV cm−1. Finite element simulations along with experimental test results demonstrate that greatly improved breakdown strength is ascribed to uniform and horizontal alignments of Na0.5Bi4.5Ti4O15 sheets (~1–2 μm) in the matrix and interface effect of adjacent layers with large dielectric differences, which effectively inhibit electrical tree evolution and conduction loss. …”
