PEDOT:PSS as multi-functional composite material for enhanced Li-air-battery air electrodes.

Unlabelled: We propose

Pedot: PSS as a multi-functional composite material for an enhanced Li-air-battery air electrode. The

Pedot: PSS layer was coated on the surface of carbon (graphene) using simple method. A electrode containing

Pedot: PSS-coated graphene (PEDOT electrode) could be prepared without binder (such as PVDF) because of high adhesion of

Pedot: PSS. PEDOT electrode presented considerable discharge and charge capacity at all current densities. These results shows that

Pedot: PSS acts as a redox reaction matrix and conducting binder in the air electrode. Moreover, after cycling, the accumulation of reaction products due to side reaction in the electrode was significantly reduced through the use of

Pedot: PSS. This implies that

Pedot: PSS coating layer can suppress the undesirable side reactions between the carbon and electrolyte (and/or Li2O2), which causes enhanced Li-air cell cyclic performance.
