Can aluminum/polymer hybrid film be used for lithium-ion batteries?

The use of aluminum/polymer hybrid (Al/polymer) film as the package materials of lithium-ion batteries (LIBs) has been extensively investigated in various studies [1,2]. They limited the measurement of the properties only to the composite level, not layered properties.

Are high-temperature dielectric films suitable for energy storage?

Summary of high-temperature dielectric films recently developed for energy storage. Crosslinking is a good strategy to limit the molecular chain motion and is studied in several published works, demonstrating the reduced dielectric relaxation, improved breakdown strength, and efficiency of the film capacitors.

Why are pp-based films used for pouch films?

PP-based films are widely used for pouch films due to their various properties, including mechanical stability, insulation properties, and thermal stability. However, PFA-300% shows higher strength compared to other polyolefin and fluorine-based films due to the orientation of crystalline phases (Fig. 9b) [39–49].

Why are high temperature and Stiff polymer films important?

Under a high electric field, the elastic modulus of polymers and the thickness can decrease due to Maxwell's electrostatic stress, thus producing the so-called electromechanical breakdown . Therefore, high temperature and stiff polymer films are desirable to avoid these thermal-mechanical degradations.

Which film processing techniques are improved to produce thinner polymer films?

Fig. 13 shows that the film processing techniques are improved to produce thinner polymer films in the following order: single layer melt extrusion, co-extrusion of nanolamination, in-situ Multi-Layer-Polymer with e-beam radiation of solution, CVD, and ALD.

Does polymer film processing reduce surface defects in thin films?

The presence of surface defects and roughness during polymer film processing may sometimes lead to local electric polarization and accelerated breakdown. A recent multilayer polymer design suppresses the surface defects in thin films . Computer simulation supports the reduction of defect contribution but lacks rigorous experimental proof.
