Unlocking High‐Performance Supercapacitor Behavior and Sustained Chemical Stability of 2D Metallic CrSe<sub>2</sub> by Optimal Electrolyte Selection
Abstract
<jats:title>Abstract</jats:title><jats:p>Supercapacitors are energy storage devices with the ability to rapidly charge and discharge, making them a valuable complement to battery systems. To maximize their fast‐charging capabilities, identifying materials and methods to enhance their energy density is crucial. In this work, we carried out a comprehensive study of an emerging 2D dichalcogenide, CrSe<jats:sub>2</jats:sub>, as a supercapacitor material. We demonstrate that CrSe<jats:sub>2</jats:sub> can be obtained at ambient temperature through deintercalation of a relevant KCrSe<jats:sub>2</jats:sub> precursor using a 0.5 M solution of I<jats:sub>2</jats:sub> in acetonitrile. Although CrSe<jats:sub>2</jats:sub> decomposed in 1 M KOH, it was found to be chemically stable in common electrolytes such as H<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub>, Li<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub>, and Na<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub>. Despite low surface area CrSe<jats:sub>2</jats:sub> reached a specific capacitance of 27 F g<jats:sup>−1</jats:sup> in 1 M H<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub> and, thus consistently outperformed high surface carbon black. Computational studies suggested that the metallic conductivity of CrSe<jats:sub>2</jats:sub> was likely the primary factor contributing to the superior performance of this 2D chalcogenide over high surface carbon analogues.</jats:p>
