ETHYLENE OXIDE-ETHYLENE TEREPHTHALATE SEGMENTED COPOLYMER SOLID ELECTROLYTE8

Received Date: 11 February 1991

A series of ethylene oxide-ethylene terephthalate segmented copolymers (EOET) weresynthesized and complexed with LiClO4 to form some new polymer electrolytes. The EOET-LiClO4 electrolytes exhibit not only high ionic conductivity, but also good mechanical strengthand toughness. The EOET 3400--25--LiClO4 complex possesses the highest conductivity (4. 65×10-5s·cm-1 at room temperature when the ratio [Li+]/[EO] equals 1/16. The structures of these electrolytes were examined with FTIR analysis, X-ray diffraction and DSC thermograms,and the results of high ionic conductivity of the segmented copolymers were discussed.
