· NiSe

Nickel selenide (NiSe) is an intermetallic compound combining nickel with selenium, belonging to the transition metal chalcogenide family. It is primarily investigated as a layered material for electrochemical applications and emerging energy storage systems, where its tunable electronic structure and layered crystal architecture offer advantages in catalytic activity and ion transport. NiSe is notably used in supercapacitors, hydrogen evolution catalysts, and lithium-ion battery electrodes, where it competes with oxides and sulfides by delivering higher conductivity and better electrolyte accessibility in nanostructured forms.
