Novel Polymer Binder Which Have Both Ionic and Electronic Conductivity for Lithium-ion Battery |
| 초록 |
A polymeric binder having both ionic conductivity and electronic conductivity originated from PEG moiety and Thiophene moiety respectively was synthesized successfully. PEG moiety with low Tg value makes it possible to have the ionic conductivity of 3.7 X 10-5S/cm at 30oC and quite sufficient electronic conductivity of 8.7 X 10-8S/cm at room temperature. Moreover, thermal stability of the polymer was investigated by DSC, EIS analysis techniques. The cell test with cathode including the polymer binder showed high discharge capacity and stable cycle performance compared to the one with conventional PVdF binder. We expect the polymer binder having both ionic and electronic conductivity could be a good substituent of PVdF binder for all solid-state lithium-ion battery. |
