Composite polymer electrolytes based on poly(ethylene oxide)-polysiloxane/l-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide/organomontmorillonite(PEO-PDMS/1L/OMMT) were prepared 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 PPB100-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-methylimidazolium bis (trifluoromethanesulfonyl) imide / organomontmorillonite (PEO-PDMS / 1L / OMMT) were prepared 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 PPB100-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.
