摘要
Composite polymer electrolytes based on poly(ethylene oxide)-polysiloxane/l-butyl-3-methylimida- zolium bis(trifluoromethanesulfonyl)imide/organomontmorillonite (PEO-PDMS/IL/OMMT) were pre- pared and characterized. Addition of both an ionic liquid and OMMT to the polymer base of PEO-PDMS resulted in an increase in ionic conductivity. At room temperature, the ionic conductivity of sample PPB 100-OMMT4 was 2.19 × 10-3 S/cm. The composite polymer electrolyte also exhibited high thermal and electrochemical stability and may potentially be applied in lithium batteries.
