A Polythiophene-based Dual Conductive Binder for Lithium Metal Battery |
| 초록 |
A polythiophene-based conductive polymer having both ionic and electric conductivity was successfully synthesized and characterized. Thermal and electrochemical properties of the polymer were investigated by various techniques such as DSC, EIS and four probe point test. The polymer shows low Tg value with the ionic conductivity of 3.7x10-5 S/cm at 30 oC due to a presence of PEG, and it also has a sufficient electric conductivity of 8.7x10‑7 S/cm at room temperature. The polymer was utilized as a cathode binder for lithium-metal battery, resulting in improved cell performance compared to conventional PVDF binder. We believe that the polythiophene having both ionic and electric conductivity can be a promising polymer binder for all-solid lithium-metal battery system, reducing the high interfacial and cathodic resistances caused by the absence of liquid electrolyte. |
