| 제목 | Fabrication of anode with thiophene derivative copolymer for all solid polymer battery |
| 초록 | When we use lithium secondary battery, there are problems about cell life, stability and energy efficiency. To solve them, we developed a new type of lithium secondary battery to clear the interfacial resistance between electrode and electrolyte. In this study, thiophene(Th) derivative copolymers were introduced into the anode. For this, we intended to introduce 3,4-ethylene dioxy thiophene(EDOT) and 3-methyl thiophene(3MeT) for high electric conductivity. And thieno[3,4-b]pyrazine(TP) and 2,3-dimethyl thieno[3,4-b]pyrazine(DMTP) were introduced for cyclic stability. Then a copolymer comprising a combination of Th derivatives solved the low doping stability and low electric conductivity. Four types of copolymer such as poly(EDOT-co-TP), poly(3MeT-co-TP), poly(EDOT-co-DMTP) and poly(3MeT-co-DMTP) as an anode were synthesized for all solid polymer battery, and the characterization was done by FT-IR, impedance analyzer, linear seep voltammetry and cyclic voltammetry. |
