Synthesis of Graphene Composites and Their Applications in Supercapacitors

Dear Colleagues,

Graphene composites have emerged as a promising class of materials for various applications, particularly in the field of energy storage. The unique properties of graphene, such as its large surface area, high electrical conductivity, and mechanical strength, make it an ideal candidate for enhancing the performance of supercapacitors. Supercapacitors, also known as ultracapacitors, are energy storage devices that bridge the gap between conventional capacitors and batteries. They offer high power density, rapid charge–discharge cycles, and long-term stability. By incorporating graphene composites into supercapacitor electrodes, researchers have been able to improve their energy density, power density, charge–discharge efficiency, and overall performance. The graphene composites can serve as conductive porous structures, provide additional surface area for ion adsorption, and improve the electrical conductivity of the electrodes.

The applications of graphene composites, including pure and doped graphene materials, in supercapacitors have shown great promise in various fields, including portable electronics, electric vehicles, renewable energy systems, and wearable devices. They offer potential solutions for addressing energy storage challenges and advancing the development of efficient and sustainable energy storage technologies. In summary, the synthesis of graphene composites and their applications in supercapacitors represents an exciting research area that combines the unique properties of graphene with the high-performance requirements of energy storage devices. This Special Issue will explore the advancements in synthesizing graphene composites and their potential impact in revolutionizing energy storage technologies for various applications. We welcome scholars and experts in this field to contribute.
