Which ferroelectric materials improve the energy storage density?

Taking PZT, which exhibits the most significant improvement among the four ferroelectric materials, as an example, the recoverable energy storage density has a remarkable enhancement with the gradual increase in defect dipole density and the strengthening of in-plane bending strain.

How can flexible ferroelectric thin films improve energy storage properties?

Moreover, the energy storage properties of flexible ferroelectric thin films can be further fine-tuned by adjusting bending angles and defect dipole concentrations, offering a versatile platform for control and performance optimization.

What is the recoverable energy storage density of PZT ferroelectric films?

Through the integration of mechanical bending design and defect dipole engineering, the recoverable energy storage density of freestanding PbZr 0.52 Ti 0.48 O 3 (PZT) ferroelectric films has been significantly enhanced to 349.6 J cm −3 compared to 99.7 J cm −3 in the strain (defect) -free state, achieving an increase of ≈251%.

How can energy storage and conversion be realized in ferroelectrics?

Scientific Reports 15, Article number: 7446 (2025) Cite this article The energy storage and conversion in ferroelectrics can be realized through the microstructures of polar domains and domain walls, which resulting in the transformations from macro/microdomains to nanodomains or forming complex polar topologies.
