Nano-Electrodes for High-Performance Supercapacitors

Dear Colleagues,

Supercapacitors are one of the important energy storage devices that bridge the gap between traditional capacitors and batteries. Supercapacitors offer high power density, fast charging and discharging rates, and long cycle life, making them ideal for applications in electronic devices, electric vehicles, medical equipment, and portable electronics. However, several limitations and challenges restrict the extensive utilization of supercapacitors in industrial applications, such as energy density, voltage limit, size, integration, etc.

Nano-electrodes, fabricated from nanostructured materials, play a crucial role in developing high-performance supercapacitors. Nano-electrodes offer an increased surface area compared to conventional electrodes, providing a high density of active sites for electrochemical reactions. The nanostructure of these electrodes facilitates rapid charge transport with short diffusion pathways and enhanced conductivity. Meanwhile, nanostructured electrodes can optimize ion diffusion and electrolyte accessibility, facilitating fine-tuning capability that allows for tailored electrochemical performance. Additionally, nano-electrodes with adjustable dimensions enable the integration of supercapacitors into flexible wearable electronics, smart textiles, and flexible displays, facilitating the development of innovative applications for various industries.

This Special Issue offers a platform for researchers to share advancements in nano-electrodes for high-performance supercapacitors. We sincerely invite researchers and experts to contribute to this Special Issue with communications, full research articles, and reviews focusing on novel developments of nano-electrodes for supercapacitors, as well as storage mechanism analysis.
