WHEN MORE GROUPS EQUAL BETTER PERFORMANCE

Polymer energy storage performance

Among various dielectric materials, polymers have remarkable advantages for energy storage, such as superior breakdown strength (Eb) for high-voltage operation, low dissipation factor (tan δ, the ratio of the imaginary part to the real part of the complex dielectric constant of dielectrics) for high charge–discharge efficiency (η), good flexibility for variable device configurations, and self-clearing ability for higher device reliability 6, 7, 8, 9, 10.

FAQS about Polymer energy storage performance

How to improve high temperature dielectric energy storage of polymer films?

How to improve room-temperature energy storage performance of polymer films?

The strategies for enhancing the room-temperature energy storage performance of polymer films can be roughly divided into three categories: tailoring molecular chain structure, doping functional fillers, and constructing multilayer structure.

How do nanoscale polymers affect energy storage performance?

As the size of fillers or thickness of introduced dielectric layers in the polymer matrix reduce to the nanoscale, the volume fraction of the nano-sized interfacial regions remarkably increases, becoming comparable to that of inorganic components, thus essentially influencing the overall energy storage performance.

Do polymer films have a microstructure and performance relationship?

While high-temperature dielectric energy storage has garnered attention, in-situ studies on the microstructures of polymer films are extremely rare, which hinders the establishment of a microstructure-performance relationship.

Are polymer-based composites a promising strategy for energy storage dielectric materials?

Polymer-based composites have become a promising strategy for developing the novel energy storage dielectric materials used in supercapacitors because of their ability to integrate the high Eb and flexibility of polymer matrices, the high energy storage performance of inorganic ceramics, and the various advantages of other fillers.
