제목 Electrochemical Characteristics of Poly(3-methyl thiophene)/Sulfonated-SEBS Composite Electrode for Polymer Battery
초록 We, in this study, propose the effect of the sulfonated binder in electrochemical system. First, poly(3-methyl thiophene, P3MT) was polymerized by using FeCl3 as both a dopant and an initiator. SEBS as a binder was sulfonated to enhance the electrochemical properties. The cathode was prepared to combine 3PhT: super-P: binder (10: 1: 1 wt.%) on Al mesh. The organic electrolyte and anode were used 1 M LiPF6 + PC/DMC and Li on Ni mesh, respectively. The specific discharge capacity of P3MT-SSEBS electrode is high as 80 mAh/g, while that of P3MT-SEBS or P3MT-PVDF one has lower values as 50 or 20 mAh/g, respectively. The reason for this is that the sulfonated SEBS acts as a binder as well as a dopant. In an advance, the effect of sulfonation promotes the miscibility, contact area and affinity.
