Interface and energy storage breakdown

Can Multi-Interface regulation improve energy storage properties of polymers?

By implementing a multi-interface regulation strategy, the energy storage properties of polymers can be effectively improved across a broad spectrum of temperatures, making it highly important to the exploration of dielectric capacitors. 2. Experimental section 2.1. Materials

What is interface engineering?

Interface engineering offers an innovative solution to address interfacial issues arising from the incorporation of reinforcing fillers, providing an additional strategy for fabricating dielectric films for high-temperate energy storage applications.

What is the discharge energy density at the hierarchical interface?

The division of labour effects at the hierarchical interface yields a discharge energy density of 8.12 J cm −3 at 640 MV m −1 under room temperature and 5.2 J cm −3 at 520 MV m −1 when subjected to a temperature of 150 ℃ for the polymer composites.

Do BNNS-F/Pei composite films have high-temperature energy storage capabilities?

In summary, we present BNNS-F/PEI composite films with high-temperature energy storage capabilities achieved through fluorinated interface engineering. The composite films demonstrate a remarkable Ue of 5.73 J/cm 3, coupled with an ultrahigh η of 91.22 % at 150 °C. This high Ue value is attributed to the enhanced Eb, reaching up to 589 kV/mm.

Why is BNNS a good dielectric film for high-temperature energy storage?

The preparation process ensures that the PEI matrix remains intact and undamaged, while the crystalline structure of BNNS fillers is also preserved. As a dielectric film for high-temperature energy storage, its glass transition temperature (Tg) is considered as a decisive factor.
