Abstract
Chelation with the diethyldithiocarbamate ligand yields a novel semiconducting Cu2S: Sb2S3: Ni3S2 metal chalcogen. The current work intends to improve the performance of charge storing contraptions for the first time by using dithiocarbamate ligands. Having a band gap of 2.55 eV and diverse crystallographic features with a median crystallite size of 44.21 nm, this photo-active material exhibits exceptional optical performance. Infrared spectroscopy identified metallic sulfide connections, ranging from 519 to 909 cm−1. The electrochemical characteristics of the Cu2S: Sb2S3: Ni3S2 was evaluated utilizing a KOH background electrolyte (1 M) and a standard three-electrode arrangement. The trichalcogenide has a power density of 7053.64 W kg−1 and a very substantial unit capacity of as high as 487.36 mAh g−1, making it the perfect electrode material for battery applications. The similar serial resistance (Rs) of 0.09 Ω further confirmed the excellent electrochemical result. Chronoamperometric analysis over 1500 min showed stable electrochemical behaviour of the Cu2S: Sb2S3: Ni3S2 composite.
