The strategy effectively suppresses electron multiplication effects, enhancing the thermal conductivity and mechanical modulus of dielectric polymers, and thus improving electric energy storage capacity. Briefly, the key problem of polymer dielectric energy storage materials is to enhance their dielectric permittivity.
Briefly, it has been demonstrated that combining various organic components (e.g., high breakdown and/or high polarization), and multicomponent dielectric films (e.g., polymer blends, multilayer and gradient polymers) is very effective for improving energy storage properties at high fields.
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.
Supercapacitors and batteries are two examples of electrochemical devices for energy storage that can be made using bespoke biopolymers and their composites. Although biopolymers’ potential uses are restricted, they are nevertheless useful when combined with other materials to create composites.
Polymeric-based dielectric materials hold great potential as energy storage media in electrostatic capacitors. However, the inferior thermal resistance of polymers leads to severely degraded dielectric energy storage capabilities at elevated temperatures, limiting their applications in harsh environments.
The energy efficiency of biopolymer-derived energy storage devices is closely tied to the stability of the materials used and their ability to maintain performance under varying environmental conditions.
