Exploration of Two-Dimensional Mixed Metal Oxide Nanocomposites for the Fabrication of High Energy Density Supercapacitors

Dear Colleagues,

Supercapacitors are emerging as a highly efficient technology among various energy storage solutions since these devices can store electrical charge in an electric double layer at the interface of an electrode and electrolyte. The global supercapacitor market is expected to reach an estimated $1.5 billion by 2028 with a CAGR of 14.5% from 2023 to 2028. Moreover, this is projected to double in the coming years due to increasing demand. In recent years, various specialized electrode materials have been developed to create high-performance supercapacitors with improved energy density, cycling stability, and capacitance, and diverse synthetic methods have been devised to produce different types of supercapacitors, including flexible, wearable, hybrid, and micro-supercapacitors. It is anticipated that these supercapacitor devices will have a significant impact on the electronics industry in the near future.

This open access Special Issue aims to compile original research, mini-reviews, research prospects, and comprehensive state-of-the-art studies on the latest advancements in supercapacitor technologies. The focus will be on novel synthetic approaches, innovative electrode materials, and unique device fabrication techniques for supercapacitor applications. The primary objective of this Special Issue is to present the most recent cutting-edge innovations in supercapacitor technologies and researchers are encouraged to submit their work related to the synthesis strategies and fabrication techniques of supercapacitors.

Topics covered:

1. Metal oxide/sulfide-based nanocomposites;
2. Two-dimensional layered double hydroxide composites;
3. Spinel perovskite nanocomposites;
4. Polymer matrix nanocomposites;
5. Carbon nanotube composites;
