Abstract
Composite polymer electrolytes were prepared by introducing nano-scale SiO_(2)into PEO_(8)-LiClO_(4)matrix. The ionic conductivity, lithium transference number and the electrochemical stability windows were measured. The phase component was evaluated with DSC techniques. The results showed that the introduction of nano fillers enhanced the ionic conductivity. It reached 4.3×10~(-5 ) S·cm~(-1)at 22 ℃. The conductivity enhancement of the composite polymer electrolytes is analyzed and proposed.
