High-Entropy Alloys and Oxides as Supercapacitor Electrodes: A Structural and Electrochemical Perspective for Energy Storage (Adv. Sustainable Syst. 6/2025)

Abstract

Supercapacitor Electrodes

This cover illustrates the integration of high entropy alloys (HEAs) and high entropy oxides (HEOs) into supercapacitor technology. The colorful, multi-metallic structure highlights the synergy between Cr, Fe, Mn, V, and Ni—five transition metals that form a highly capacitive, stable, and efficient electrode material. These high entropy materials demonstrate outstanding charge storage performance, reinforcing the energy and power density of supercapacitor devices.
