High electrocatalytic activity of an electropolymerized film of poly (3,4-ethylenedioxythiophene) (PEDOT) was reported toward the redox reaction of 2,5-dimercapto-1,3,4-thiadiazole (DMcT) as a promising cathode material for the lithium ion battery. Electrochemical performance of DMcT was improved by adding an appropriate quantity of PEDOT. Cyclic voltammetry showed improved electrochemical performance of DMcT on PEDOT-coated Pt electrode, indicating accelerated redox kinetics. Moreover, charge-discharge tests exhibited higher discharge capacity and slower capacity fading of the PEDOT-doped DMcT composite cathode compared with pure DMcT.
