Polypyrrole (PPy) was made by an emulsion polymerization using iron(III) chloride (FeCl3) as an initiator and dodecyl benzene sulfuric acid (DBSA) as an emulsifier and dopant. Poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) was sulfonated by chlorosulfonic acid (CSA). The cathode was composed of PPy+DBS- complex, conductor powder, and PPO or sulfonated poly (2,6-dimethyl-1,4-phenylene oxide) (SPPO) as a binder or dopant. The charge-discharge performance of PPy+DBS-/SPPO cathode was increased as the extent of about 50% than PPy+DBS-/PPO. This is because SPPO played a role as a binder as well as a dopant. In addition, sulfonation brings out the increase of miscibility between PPy and SPPO, and the increase of contact area between cathode and electrolyte.
