Advancements in Dielectric Capacitors Utilizing Soft Materials: A Comprehensive Investigation into Innovative Energy Storage Systems

Dielectric capacitors play a fundamental part in energy storage systems. Owing to the advancements in materials engineering, polymers have a significant role in the fabrication of efficient dielectric capacitors for improved energy storage. Due to the incorporation of different inorganic fillers, the already-favourable dielectric properties of polymers are further improved, hence obtaining polymer composites with high dielectricconstants, breakdown strengths, low dielectric losses and high energy densities. Besides the incorporation of inorganic fillers, the synthesis of all-organic dielectric materials allows obtaining materials with superior dielectric properties. The enhanced energy storage of the all-organic materials arises from the excellent compatibility between the organic phases. Due to the ability to tailor the dielectric and mechanical properties of polymers, combined with the easy processing and relatively low cost, this class of materials is increasingly used in various fields, including energy storage systems.
