Solid Polymer Electrolytes Based on Cross-linkable Oligo （oxyethylene） -Branched Oligo （organophosphazenes）

Solid polymer electrolytes have attracted considerable interest because of their potential application in secondary high energy density lithium batteries. The poly（ethylene oxide）（PEO） has been widely studied as the classical polymer matrix for solid polymer electrolytes. However, the poor room temperature conductivity due to its crystalline is the principal problem to be overcomed. This has prompted many researchers to attempt to modify the properties of PEO.
