A binder-free facile synthetic approach for amorphous, hydrous nickel copper phosphate thin film electrode preparation and its application as a highly stable cathode for hybrid asymmetric supercapacitors

Abstract

Currently, amorphous, hydrous compounds are receiving much attention as an electrode in hybrid supercapacitors (SCs) as it offer extraordinary electrochemical efficiency because of disorder in structure and excellent electrochemical interface....

Advancements in 2D MXene-based supercapacitor electrodes: synthesis, mechanisms, electronic structure engineering, flexible wearable energy storage for real-world applications, and future prospects

“…Numerous materials have been investigated for use as electrode materials in supercapacitors, including carbon-based materials, 17,18 transition metal oxides, 19,20 transition metal nitrides, 9,21 transition metal dichalcogenides, 22,23 transition metal phosphates, 24,25 and polymers. 26,27 But even though these materials have their own benets, they face challenges and restrictions that prevent them from reaching their maximum potential.…”
