摘要

Abstract

Solid polymer composite electrolytes possess the benefits of superior compatibility with electrodes and good thermal characteristics for more secure energy storage equipment. Herein

a new gel polymer electrolyte (GPE) containing NH

LiTFSI

and PVDF-HFP was prepared using a simple method of solution casting. The effects of encapsulating different ratios of ionic liquid ([PP

) into the micropores of functionalized metal-organic frameworks (NH

-MIL-53(Al)) on the electrochemical properties were compared. XRD

SEM

nitrogen adsorption-desorption isotherms

and electrochemical measurements were conducted. This GPE demonstrates a superior ionic conductivity of 8.08×10

at 60 ℃ and can sustain a discharge specific capacity of 156.6 mA·h·g
