Ion Conducting Behaviors of Polymeric Composite Electrolytes Containing Mesoporous Silicates

Article Preview

Abstract:

Polymeric composite electrolytes (PCE) based on poly(ethylene oxide) (PEO) and mesoporous silicates as a filler material were fabricated, and investigated for understanding the effects of filler addition into the polymer matrix on the ionic conductivity. For a lithium battery application, it is necessary to increase ion conductivity of PCE by modification of microstructure. The ionic conductivity was enhanced with increasing MCM-41 contents due to the decreased crystallinity of PEO. Furthermore, the regular mesoporous structure could be functioned as an ion transfer channel for high ion mobility.
