Rechargeable lithium batteries with a high-specific energy are promising power sources for modern portable electronic products and electric vehicles. Poly(ethylene oxide) (PEO) had been extensively studied due to high ionic conductivity in the amophous phase, high capacity in salt complexation, mechanical flexibility, and chemical stability. By preparation of composite electrolytes containing nano-size ceramic fillers or organic materials, the electrochemical and mechanical properties could be improved. In this work, the conducting polymer composite electrolytes were made by using PEO, ethylene oxide oligomers and clay materials. The influence of clay materials as additives on the ionic conductivities and the interfacial characteristics was analyzed. It could be found that the ionic conductivity of the composite electrolytes showed improved behaviors due to the decreased crystallinity and better ion transfer by addition of additive materials. |
