Chemically deposited nano grain composed MoS2 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 1 M aqueous Na2SO4 electrolyte. Specific capacitance (C-s) of 180 Fg(-1) with CV cycling Stability of 82 % for 1000 cycles is achieved. Equivalent series resistance (R-s) of 1.78 Omega cm(-2) observed through Nyquist plot shows usefulness of MoS2 thin film for charge conduction in supercapacitor application.
