High energy storage performance film application

Are polymer capacitive films suitable for high-temperature dielectric energy storage?

While impressive progress has been made in the development of polymer capacitive films for both room-temperature and high-temperature dielectric energy storage, there are still numerous challenges that need to be addressed in the field of dielectric polymer and capacitors.

Why is thin film a good choice for energy storage?

The thin film exhibits excellent stability in energy storage performance, a wide working frequency range (0.5–20 kHz), a broad operating temperature window (20–200 °C), and reduplicative switching cycles (10 7 cycles).

Can polymer-based dielectric films improve high-temperature energy storage performance?

Both the discharged energy density and operation temperature are significantly enhanced, indicating that this efficient and facile method provides an important reference to improve the high-temperature energy storage performance of polymer-based dielectric films.

Are high-temperature polymer dielectric films suitable for harsh-environment applications?

High-temperature polymer dielectric films are in great demand for harsh-environment applications. However, it remains a major challenge to achieve high discharged energy density and high charge–discharge efficiency due to severe conduction loss at elevated temperatures.

Are Pei-based polymer films suitable for high-temperature energy storage applications?

In particular, PEI-based polymer films have been the most favorable materials and exhibit great potential for use in high-temperature energy storage applications.

How can we improve the energy storage of polymer films?

Molecular chains modulation, doping engineering, and multilayered design have been the three main approaches to improving the energy storage of polymer films under extremely high-temperature conditions.
