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.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.
