Summary

Recently, chalcogenide materials have attracted considerable attention due to their unique physicochemical properties, which enable their use in a wide range of energy and electronicsrelated applications. Understanding their electrochemical behavior has become increasingly important, as performance in realworld operating environments is often governed by complex electrochemical processes.

Given their relevance in technologies such as batteries and supercapacitors, it is essential to clarify the mechanisms that drive their degradation and their response to various environmental conditions. Despite significant progress, major knowledge gaps remain in correlating chemical composition and structure with electrochemical performance. Advanced characterization techniques—such as electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and cyclic voltammetry (CV)—are critical for elucidating these fundamental mechanisms and guiding the design of improved chalcogenidebased materials.

This Special Issue aims to gather original research and review articles focused on the electrochemical behavior and degradation mechanisms of chalcogenide materials. Particular emphasis is placed on understanding the relationships between structure, composition, and performance across different applications. Topics of interest include:
· Modeling and simulation of electrochemical processes;
· Structure–property–electrochemistry correlations in chalcogenide materials;
· Oxidation processes and degradation pathways of chalcogenide materials.
