Novel gel polymer electrolytes based on alkylene oxide macromonomer

A novel gel polymer electrolyte, based on alkylene oxide macromonomer, was specially designed and synthesized for gel electrolyte purpose. A tri-funct ional macromonomer having a molecular weight of 8000 revealed to be the bes t candidate for preparing the gel electrolyte from the mechanical property aspect. The liquid retention ability of the cross-linked network polymer pr epared from the above macromonomer was explored. It was confirmed that the polymer network based on the macromonomer retained a large amount of liquid electrolyte over 80 wt.% in stable state. (C) 2000 Elsevier Science Ltd. A ll rights reserved.
