Abstract

Polymer-based composites are widely regarded as the most promising materials for energy storage applications. However, their widespread use is currently limited by relatively low energy storage density and suboptimal performance at high temperatures. In this study, a novel polyetherimide (PEI)-based multilayered composite, featuring BaTiO₃ nanofibers in the intermediate layer and boron nitride nanosheets in the outer layer, was fabricated. Owing to the synergistic enhancement of polarization and breakdown strength resulting from this innovative structural design, the optimal BN/BTNFs/PEI composite demonstrated exceptional energy storage performance with 22 J/cm³, which remained stable even under high-temperature conditions.
