Controllable fabrication of nickel sulfides with enhanced electrochemical performance

Author affiliations

Abstract

In this work, nickel sulfides are fabricated from thiourea and Ni precursor through a hydrothermal method. Experiment results show that nickel sulfides can be controllably synthesized. Sulfuration time influences the composition and particle size of nickel sulfides. It is found that the particle size and composition of nickel sulfides influence the electrochemical properties. Impressively, the obtained nickel sulfides demonstrate high electrochemical performance with an optimal gravimetric capacity of 249.5 mA h gāˆ’1 at a current density of 2 A gāˆ’1. Proper particle size and composition of nickel sulfides are thought to contribute to their impressive electrochemical performance.
