In the present work, the synergistic combination of mechanical bending and defect dipole engineering is demonstrated to significantly enhance the energy storage performance of freestanding ferroelectric thin films, achieved through the generation of a narrower and right-shifted polarization-electric field hysteresis loop.
Although several mechanical characters can describe the bending status of the flexible energy storage devices, the simplest property is their bending endurance under a given radius.
Furthermore, as the degree of bending increases, the flexoelectric field also becomes more pronounced, leading to a more significant shift in the Pz - Ez hysteresis loops and ultimately resulting in an enhanced energy storage density.
Bending Mechanics of Energy Storage Devices In a monocomponent system, physical deformation appears around the entire structure after applying an external bending motion on devices. Then, interior stress is produced to resist shape variation.
Under the same applied external electric field, an increase in bending tensile strain leads to a gradual reduction in the out-of-plane polarization component Pz, causing a rightward shift in the Pz - Ez hysteresis loop of BTO and ultimately enhancing the energy storage density.
In the present work, the synergistic combination of mechanical bending and defect dipole engineering is demonstrated to significantly enhance the energy storage performance of freestanding ferroelectric thin films, achieved through the generation of a narrower and right-shifted polarization-electric field hysteresis loop.
In general, realizing the ultimate improvement of the mechanical performance of energy storage devices is challenging in the theoretical and experimental research of flexible electronics.
