Abstract

Lithium-ion batteries (LIBs) benefit from an effective electrolyte system design in both terms of their safety and energy storage capability. Herein, a series of precursor membranes with high porosity were produced using electrospinning technology by mixing PVDF and triblock copolymer (PS-PEO-PS), resulting in a porous structure with good interconnections, which facilitates the absorbency of a large amount of electrolyte and further increases the ionic conductivity of gel polymer electrolytes (GPEs). It has been demonstrated that post-cross-linking of the precursor membranes increases the rigidity of the nanofibers, which allows the polymer film to be dimensionally stable up to 260 °C while maintaining superior electrochemical properties. The obtained cross-linked GPEs (CGPEs) showed high ionic conductivity up to 4.53×10−3 S·cm−1. With the CGPE-25, the assembled Li/LiFePO4 half cells exhibited good rate capability and maintained a capacity of 99.4% and a coulombic efficiency of 99.3% at 0.1 C. These results suggest that the combination of electrospinning technique and post-cross-linking is an effective method to construct polymer electrolytes with high thermal stability and steadily decent electrochemical performance, particularly useful for Lithium-ion battery applications that require high-temperature usage.

用于锂离子电池的交联电纺丝凝胶聚合物电解质
锂离子电池(LIB)的安全性和储能能力都得益于有效的电解质系统设计。本文利用电纺丝技术,通过混合聚偏二氟乙烯(PVDF)和三嵌段共聚物(PS-PEO-PS),制备了一系列具有高孔隙率的前体膜,从而形成了具有良好互联性的多孔结构,有利于吸收大量电解质,并进一步提高凝胶聚合物电解质(GPE)的离子传导性。研究表明,前体膜的后交联增加了纳米纤维的刚性,这使得聚合物膜的尺寸稳定性可高达 260 °C,同时保持优异的电化学性能。获得的交联 GPE(CGPE)显示出高达 4.53×10-3 S-cm-1 的离子电导率。这些结果表明,结合电纺丝技术和后交联技术是构建具有高热稳定性和稳定的电化学性能的聚合物电解质的有效方法,尤其适用于需要高温使用的锂离子电池应用。

期刊介绍: Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985. CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
