Superior Electrochemical Properties

Nano-materials with ordered structures exhibit the valuable application in the domain of supercapacitors due to the internal structural advantages. Herein, one-dimensional nickel sulfide nano-arrays were prepared by a one-pot solvothermal method. When applied as the binder-free electrodes of supercapacitors, one-dimensional nickel sulfide nano-arrays can achieve superior electrochemical properties. It is particularly important that solidstate hybrid supercapacitors based on one-dimensional nickel sulfide nano-arrays and commercial activated carbon can achieve the areal energy density of 0.355 mWh cm–2 and stable voltage window of 0–1.6 V. In the meantime, the current hybrid supercapacitors can deliver the outstanding working lifetimes and the higher practical value. Such exciting results demonstrates that one-dimensional nickel sulfide nano-arrays have the wide application prospects in the field of small, lightweight, and mobile electronic products.
