摘要

利用静电纺丝技术和傅-克烷基化反应制备了以聚偏氟乙烯(PVDF)为基体，聚苯乙烯-聚环氧乙烷-聚苯乙烯(PS-PEO-PS)三嵌段共聚物为添加剂的交联纳米纤维复合膜(e-CPMs). 将e-CPMs浸泡电解液活化，即可得到交联凝胶聚合物电解质(e-CGPEs). 通过改变PS-PEO-PS的含量(3%、5%、10%、20%)研究了PS-PEO-PS对e-CPMs热稳定性及e-CGPE电化学性能的影响. 结果表明，e-CPMs的高温尺寸稳定性优于PVDF膜和商业化聚丙烯(PP)隔膜. 当PS-PEO-PS的添加量达到5%时，e-CGPE 5%的室温离子电导率可达6.52 mS/cm. 在2 C充放电，e-CGPE 5%放电比容量仍可达83.5 mAh/g. 在0.1 C循环100次后，e-CGPE 5%的放电容量保持率高达99.7%.

Abstract

Gel polymer electrolytes (GPEs) for lithium ion batteries (LIBs) have attracted great attention due to their high ionic conductivity and safety

but it is still a great challenge to develop GPEs which can be used at high temperature in specific applications

such as oil drilling

mining

military and aerospace electronics. Cross-linking is one of the efficient methods for enhancing the thermal stabilities of GPEs. In this work

crosslinked gel polymer electrolytes (e-CGPEs) were made by electrospinning and Friedel-Crafts alkylation reaction. First of all

electrospun polymer membranes (e-PMs) were prepared by electrospinning technique with poly(vinylidene fluoride) (PVDF) as the matrix and polystyrene-

-poly(ethylene oxide)-

-polystyrene (PS-PEO-PS) triblock copolymer as the additive. Then the styrene units in e-PMs were crosslinked by Friedel-Crafts alkylation reaction to give electrospun crosslinked polymer membranes (e-CPMs). e-CPMs were activated by absorbing electrolytes to give crosslinked gel polymer electrolytes (e-CGPEs). The effects of PS-PEO-PS content (3%

10%

20%) on the properties of e-CPMs and e-CGPEs were also discussed. The results show that the content of PS-PEO-PS can affect the crystallinity

electrolyte uptake and crosslinked degree of e-CPMs

which may have influences on the ionic conductivity. Owing to the abundant crosslinked networks

high-temperature dimensional stabilities of e-CPMs are much better than that of electrospun PVDF membrane and commercial polypropylene (PP) membrane. All e-CPMs show almost no dimensional shrinkage at 160 °C

indicating that e-CPMs can be efficient precursors of GPEs used at high temperature. e-CGPEs have better electrochemical performances than the PVDF-based GPE (e-PVDF)

due to their high porosity

electrolyte uptake and ionic conductivity. Among all the e-CGPEs

e-CGPE 5% with proper PS-PEO-PS content and crosslinked degree possesses the highest ionic conductivity of 6.52 mS/cm at room temperature. The half-cell assembled by e-CGPE 5% shows a discharge specific capacity of 83.5 mAh/g at 2 C. e-CGPEs also exhibit excellent cycle and rate performances. e-CGPE 5% has a capacity retention of 99.7% after 100 cycles at 0.1 C. All the results suggest that e-CGPEs have potential application value in high-efficiency lithium ion batteries which could be used at high temperature. And this work also provides a new path for the preparation of crosslinked gel polymer electrolytes with high efficiency and good performance.
