In-situ diepoxidesiloxane-based polymer electrolyte for lithium-ion batteries |
| 초록 |
The safety issues of lithium-ion batteries caused by liquid organic electrolytes have been driving individuals to seek safer electrolytes. A series of diepoxide siloxane-based polymer electrolytes have been fabricated and characterized. Herein, an in-situ crosslinking strategy was used to reduce the interface impedance between electrodes and polymer electrolyte. The obtained polymer electrolyte shows high ionic conductivity (1.16×10−4 S cm−1 at room temperature) and electrochemical window up to 4.0 V (vs. Li/Li). Meanwhile, LiCoO2/polymer electrolyte /Li shows a specific discharge capacity of 129 mAh g−1 at 0.1 C. this work indicates that polydiepoxidesiloxane crosslinked by in-situ strategy yields a high-performance polymer electrolyte for future polymer electrolyte lithium-ion batteries. |
