| 英文摘要 | The increasing interest in gel polymer electrolyte for the lithium battery is attributed to its excellent plasticity, enhanced safety and significantly improved electrochemical stability. Herein, on account of the two-phase structure of thermoplastic polyurethane (TPU) consisting of soft and hard segments, the cellulose/TPU with ether bond composite gel polymer electrolyte (CGPE) was fabricated and investigated for applications in lithium batteries. This study demonstrated that the CGPE possessed preeminent comprehensive properties such as sufficient ionic conductivity (4.8 x 10(-4) S cm(-1)) at 80 degrees C, high lithium ion transport number (t(+) = 0.68) and improved electrochemical stability. Moreover, the assembled LiFePO4/Li battery using CGPE exhibitedoutstanding rate capacity and remarkable cycle performance at the elevated temperature of 80 degrees C. Notably, the discharge capacity was still 128.2 mAh g(-1) after 200 cycles, 95% of the capacity retention at a charge/discharge rate of 2C. These findings suggest that CGPE is a very prospective polymer electrolyte for high-performance lithium batteries. (C) 2016 Elsevier Ltd. All rights reserved. |
