Chemically deposited nano grain composed MoS(2) thin films for supercapacitor application

Low temperature soft chemical synthesis approach is employed towards MoS₂ thin film preparation on cost effective stainless steel substrate. 3-D semispherical nano-grain composed surface texture of MoS₂ film is observed through FE-SEM technique. Electrochemical supercapacitor performance of MoS₂ film is tested from cyclic voltammetry (CV) and galvanostatic charge discharge (GCD) techniques in 1M aqueous Na₂SO₄ electrolyte. Specific capacitance (C_s) of 180Fg^-1 with CV cycling stability of 82% for 1000 cycles is achieved. Equivalent series resistance (R_s) of 1.78Ωcm^-2 observed through Nyquist plot shows usefulness of MoS₂ thin film for charge conduction in supercapacitor application.
