Polymer electrodes have several advantages like being environment friendly, mechanically flexible and more inexpensive than lithium metal which is used as lithium metal oxide-based cathode. But polymer electrodes generally have had lower charge/discharge capacity. Organothiol(-SH)/disulfide(S-S) compounds have much higher theoretical capacity than lithium metal oxide-based cathode materials. But the practical application of sulfur has been hindered because of the lack of electronic conductivity which causes the loss of capacity and poor charge/discharge durability. Then this study is focused on enhancing electrical properties of the polymer electrode. Disulfide bonds are linked to the side chain of polyaniline and formed conjugated crosslinking between polymer chains in order to improve the electronic conductivity. As a result, as the contents of ADTTAA increased, charge/discharge capacity was increased but the conductivity and cycle life was decreased. |
