Experimental report on energy storage test of thin film materials

Does a ferroelectric thin film have a high energy storage response?

Adv Mater, 2014, 26: 4763–4782 Nguyen CTQ, Nguyen MD, Vu HT, et al. High energy storage responses in all-oxide epitaxial relaxor ferroelectric thin films with the coexistence of relaxor and antiferroelectric-like behaviors. Thin Solid Films, 2017, 636: 188–192 Wu Y, Cao C.

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%.

Are thin films suitable for chromogenic applications?

Thin films have the ability to exist as multiple layers, including but not limited to thin-film solar cells and electrochromic (EC) cells . Multilayer thin films possess favorable characteristics that render them appropriate for a wide range of technological applications, including chromogenic applications.

Do ultra-thin layers improve energy storage performance?

However, the energy density of these dielectric films remains a critical limitation due to the inherent negative correlation between their maximum polarization (Pmax) and breakdown strength (Eb). This study demonstrates enhanced energy storage performance in multilayer films featuring an ultra-thin layer structure.

Does ultra-thin N24 film improve energy storage performance?

Ultimately, in the ultra-thin N24 film, with each layer having a thickness of 6.7 nm, we achieved a remarkable enhancement of energy storage performance, with Wrec reaching 65.8 J/cm −3 and efficiency reaching 72.3%. 2. Experimental 2.1. Synthesis of BiFeO 3 and SrTiO 3 precursors

Why should multilayered thin films be investigated?

Also, multilayered thin films should be investigated since the interfaces in them act as media to generate space charges that serve as traps for injected electrons from the metal electrodes under the application of a high electric field. This is another route to improving the polarization and thus ES performance.
